1 Introduction

1.1 What is Acronis® True ImageTM?
Acronis True Image 2021 is a complete data protection solution that ensures the security of all of the information on your PC. It can back up your documents, photos, emails, and selected partitions, and even the entire disk drive, including operating system, applications, settings, and all of your data. One of its main features is Antivirus Protection consisting of Active Protection and Antivirus scan which is a combination of data protection and security features.
Backups allow you to recover your computer system should a disaster occur, such as losing data, accidentally deleting critical files or folders, or suffering a complete hard disk crash.
Online Backup allows you to store your files and disks on Acronis Cloud. Your data will be protected even if your computer is lost, stolen, or destroyed, and your data can be entirely recovered onto a new device, if needed.
Key features:  Disk backup to a local storage and to Acronis Cloud (p. 45)  File backup to a local storage and to Acronis Cloud (p. 47)  Antivirus and antimalware Protection (p. 123)  Acronis bootable media  Hard disk cloning (p. 138)  Data archiving (p. 115)  Family data protection (p. 119)  File synchronization (p. 132)  Security and privacy tools (p. 146)
You cannot create backups to Acronis Cloud with Acronis Startup Recovery Manager and Acronis bootable media.

 Full and quick  Scheduled and manual run  Quarantine. Configure the automatic or manual moving of suspicious files to a safe location from which they cannot harm your data.  Web filtering protects you from potentially harmful websites and untrusted web resources by blocking the access to them, based on your list of trusted or untrusted URLs.  Videoconference protection prevents injection attacks on Zoom, Cisco Webex, and Microsoft Teams.  A redesigned Web Restore page that makes the Anywhere Access to cloud data faster, more secure, and convenient.  .tibx archives can now be mounted, moved, renamed, and converted to the .vhd format.  Added quick validation for backups ­ an option to validate only the latest backup version to speed up the standard validation process.  Improved replication of backups to Acronis Cloud to support replicating via unstable internet connections. In case of a connection issue, the replication of backups to Acronis Cloud stops. When the connection is restored, the already replicated data is not replicated again and the replication continues from the point where it stopped.  Integration with Windows Security Center
1.3 Backups created in Acronis True Image 2020 or later
Acronis True Image 2020 introduced a new backup format - TIBX, which is even more reliable and convenient. The TIBX format is used for disk backups created to internal drives, external drives, network storage.
Backup file naming
With .tibx files, the file name has only the backup name and an incremental counter. It does not contain any additional information such as backup method, backup chain number, backup version number, or volume number, which were used with the TIB format.
A backup name may look like:
1. my_archive.tibx 2. my_archive_0001.tibx 3. my_archive_0002.tibx 4. my_archive_0003.tibx
Backup schemes
Backing up in the TIBX format supports all backup schemes. As opposed to the TIB format, which saves every backup version as a separate file, the TIBX format saves full and differential backup versions as separate files, while incremental backup versions are automatically merged into their base backups (full or differential).
Cleaning up TIBX format backups
If you'd like to clean up backup versions you do not need anymore, use automatic and manual cleanup methods.

8

Copyright © Acronis International GmbH, 2003-2020

In case automatic or manual cleanups are configured, some small auxiliary files may stay in the storage after the cleanup. Windows may show the size of these files bigger than the real one. You can see the physical size by checking Windows file properties.
Please do not delete any files manually!
Cleaning up local backups manually has the following scheme:  Full backups can be deleted with the dependent versions only.  Differential backup versions can be deleted independently of any other backup versions.  Incremental backups:
 If it is the last backup chain, then any incremental backup can be deleted to free up the space.
 If it is not the last backup chain, any incremental backup version can be deleted only together with all other incremental versions of the same chain.
Which backups retain TIB format
The following backups continue to use the TIB format:  File-level backups  Nonstop backups  Notarized backups  Backups which use CD/DVD/Blu-ray, FTP, or Acronis Secure Zone as their destination
To compare naming of a .tibx archive with a .tib archive in detail, please refer to Backup file naming (p. 40).
Refer to Cleaning up backups, backup versions, and replicas (p. 83) for more details about automatic cleanup.
For more details about manual cleanup, refer to Cleaning up backup versions manually (p. 84).
Mounting Images
You can mount only backups in .tib format. The .tibx format is not supported.
See Mounting an image

17

Copyright © Acronis International GmbH, 2003-2020

2.2.1 Step 1. Backing up your computer
When should I back up my computer?
Create a new backup version after every significant event in your system.
Examples of these events include:  You bought a new computer.  You reinstalled Windows on your computer.  You configured all system settings (for example, time, date, language) and installed all necessary
programs on your new computer.  Important system update.
To ensure you save a healthy state of a disk, it is a good idea to scan it for viruses before backing it up. Please use antivirus software for this purpose. Note this operation often takes a significant amount of time.

How do I create a backup of my computer?
You have two options to protect your system:  Entire PC backup (recommended)
Acronis True Image backs up all your internal hard drives in disk mode. The backup contains the operating system, installed programs, system settings, and all your personal data including your photos, music, and documents. Refer to Backing up all data on your PC (p. 20) for details.  System disk backup You can choose to back up your system partition or the entire system drive. Refer to Backing up disks and partitions (p. 45) for details.
We do not recommend using nonstop backup as a primary way to protect your system, because the main purpose of this technology is protection of frequently changed files. For the safety of your system, use any other schedule. See examples in Examples of custom schemes (p. 62). Refer to Using Acronis Nonstop Backup (p. 38) for more details about the Nonstop Backup feature.
To back up your computer:
1. Start Acronis True Image 2021. 2. On the sidebar, click Backup.
If this is your first backup, you will see the backup configuration screen. If you already have some backups in the backup list, then click Add backup. 3. Click the Backup source icon, and then select Entire PC. If you want to back up your system disk only, then click Disks and partitions, and then select your system partition (usually C:) and the System Reserved partition (if any). 4. Click the Backup destination icon, and then select a storage place for the backup (see recommendation below). 5. Click Back up now.
Result: A new backup box appears in the backup list. To create a new version of the backup in future, select the backup box from the list, and then click Back up now.
Where do I store my disk backups?  Good: Your ordinary internal hard disk.  Better: Acronis Secure Zone (p. 163). This is a special secure partition on your local hard drive for
storing backups.

18

Copyright © Acronis International GmbH, 2003-2020

 The best: Acronis Cloud (p. 28) or an external hard disk. Refer to Deciding where to store your backups (p. 35) for details.
How many backup versions do I need?
In most cases, you need 2-3 backup versions of your entire PC contents or your system disk, with a maximum of 4-6 (see above for information about when to create backups). You can control the number of backup versions by using automatic cleanup rules. Refer to Custom schemes (p. 60) for details.
Remember, the first backup version (the full backup version) is the most important. It is the biggest one, because it contains all data stored on the disk. Further backup versions (the incremental and differential backup versions) may be organized in different schemes. These versions contain only data changes. That's why they are dependent on the full backup version and why the full backup version is so important.
By default, a disk backup is created by using the incremental scheme. This scheme is optimal, in most cases.
For advanced users: it is a good idea to create 2-3 full backup versions and store them on different storage devices. This method is much more reliable.
2.2.2 Step 2. Creating Acronis bootable media
What is Acronis bootable media?
Acronis bootable media is a CD, DVD, USB flash drive, or other removable media from which you can run Acronis True Image when Windows cannot start. You can make a media bootable by using Acronis Media Builder.
How do I create Acronis bootable media?
1. Insert a CD/DVD or plug in a USB drive (USB flash drive, or an HDD/SSD external drive). 2. Start Acronis True Image 2021. 3. On the sidebar, click Tools, and then click Rescue Media Builder. 4. On the first step, select Simple. 5. Select the device to use to create the bootable media. 6. Click Proceed.
How do I use Acronis bootable media?
Use Acronis bootable media to recover your computer when Windows cannot start.
1. Connect the bootable media to your computer (insert the CD/DVD or plug in the USB drive). 2. Arrange the boot order in BIOS so that your Acronis bootable media is the first device to be
booted. Refer to Arranging boot order in BIOS (p. 100) for details. 3. Boot your computer from the bootable media and select Acronis True Image 2021. Result: Once Acronis True Image is loaded, you can use it to recover your computer.
Refer to Acronis Media Builder (p. 147) for details.

19

Copyright © Acronis International GmbH, 2003-2020

2.3 Backing up all data on your PC
What is an Entire PC backup?
An Entire PC backup is the easiest way to back up the full contents of your computer. We recommend that you choose this option when you are not sure which data that you need to protect. If you want to back up your system partition only, refer to Backing up disks and partitions (p. 45) for details.
When you select Entire PC as a backup type, Acronis True Image backs up all your internal hard drives in disk mode. The backup contains the operating system, installed programs, system settings, and all your personal data including your photos, music, and documents.
The recovery from an Entire PC backup is also simplified. You only need to choose the date to which you want to revert your data. Acronis True Image recovers all data from the backup to the original location. Note that you cannot select specific disks or partitions to recover and you cannot change the default destination. If you need to avoid these limitations, we recommend that you back up your data with an ordinary disk-level backup method. Refer to Backing up disks and partitions (p. 45) for details.
You can also recover specific files and folders from an Entire PC backup. Refer to Backing up files and folders (p. 47) for details.
If an Entire PC backup contains dynamic disks, you recover your data in partition mode. This means that you can select partitions to recover and change recovery destination. Refer to About recovery of dynamic/GPT disks and volumes (p. 98) for details.
How do I create an Entire PC backup?
To back up the entire contents of your computer:
1. Start Acronis True Image 2021. 2. On the sidebar, click Backup. 3. Click the plus sign at the bottom of the backup list. 4. Click the Backup source icon, and then select Entire PC. 5. Click the Backup destination icon, and then select a destination for the backup.

20

Copyright © Acronis International GmbH, 2003-2020

We recommend that you back up your computer to Acronis Cloud or to local or network storage. Refer to Deciding where to store your backups (p. 35) for details.

6. [optional step] Click Options to set the options for the backup, including Schedule (p. 55), Scheme (p. 58), and Password protection (p. 67). For more information see Backup options (p. 55).
7. Click Back up now.
When you back up your data to Acronis Cloud, the first backup may take a considerable amount of time to complete. Further backup processes will likely be much faster, because only changes to files will be transferred over the Internet.
Additionally, watch the English-language video instructions at https://goo.gl/KjW5sM.
2.4 Creating an Acronis Survival Kit
What is an Acronis Survival Kit?
To recover your computer in case of a failure, you need to have two crucial components--a backup of your system disk and an Acronis bootable media. Most often these components are separated, for example, the system backup is stored on an external drive or Acronis Cloud and the bootable media is a small USB flash drive. An Acronis Survival Kit combines both components so that you could have a single device that has everything that you need to recover your computer in case of a failure. It is an external hard disk drive that contains both the Acronis bootable media files and a backup of your system partition, entire computer, or any disk backup. Moreover, the backup of your data can be used as a normal backup: it can contain any data that you need to secure, you can set up Scheduling (p. 55) to update it as a normal backup. And even more, the external hard drive is not exclusively booked by the Acronis Survival Kit, its bootable media takes only 2 Gb of the disk space, and the remaining space can be shared by the system partition or entire computer backup which is the part of the Acronis Survival Kit, and by any other data including other backups, your personal data, photos, whatever. But please keep only one Acronis Survival Kit on one external hard disk.

21

Copyright © Acronis International GmbH, 2003-2020

No matter how many backups are stored in this external hard disk, only one Acronis Survival Kit is required to recover a computer. Its bootable media component works with any system partition or entire computer backup if they both are created for the same computer or computers with the same configuration.
As a device for an Acronis Survival Kit you can use:  an external hard disk drive
It should be larger than 32 GB and have an NTFS, FAT32, or exFAT file system. If the drive has another file system, Acronis True Image 2021 suggests formatting the drive.  a USB flash drive It should be an MBR flash drive with minimum size of 32 GB. If you use a GPT flash drive, Acronis True Image 2021 suggests formatting the drive to MBR. Note, flash drives are supported only for Windows 10 (build 1703 and later).
How do I create an Acronis Survival Kit?
When you configure a backup of your system partition, entire computer, or any disk backup and select an external hard disk drive as a destination, Acronis True Image 2021 will suggest creating an Acronis Survival Kit.

To create an Acronis Survival Kit:
1. Click Back up now or Create Acronis Survival Kit. 2. In the opened window, click Create.
Acronis True Image 2021 creates a small partition on the selected drive and writes the boot files there. To create it, one of the existing volumes will be resized. If the disk is not a GPT one and has a file system different from NTFS, FAT32, or exFAT, Acronis True Image 2021 suggests formatting the disk. Pay attention, that disk formatting deletes all the data stored on the disk. 3. When the boot files are successfully written to the drive, it becomes an Acronis bootable media that you can use to recover your computer. To complete creating an Acronis Survival Kit, you

22

Copyright © Acronis International GmbH, 2003-2020

need to save a backup of your system partition, entire computer, or any disk backup to this drive. To do this, click Back up now. If you skip this step, do not forget to create a backup on this drive later. Refer to Backing up disks and partitions (p. 45) for details. When your Acronis Survival Kit is ready, you can use it to recover your computer. Refer to Recovering your system to the same disk (p. 89) for details.
Every time you configure a backup to an external device with a Survival Kit on it, Acronis True Image 2021 will check its version. If an up-to-date version of the Survival Kit is available, Acronis True Image 2021 will suggest updating the Survival Kit on your external device.
2.5 Backing up your files
To protect files such as documents, photos, music files, and video files, there is no need to back up the entire partition containing the files. You can back up specific files and folders and save them to the following storage types:  Local or network storage
This option is fast and easy. Use it to protect rarely changed files.  Acronis Cloud
This option is reliable. Use it to protect critical files and files that you want to share between devices or people. To use Acronis Cloud, you must have an Acronis account and a subscription to the Acronis Cloud service. Refer to Subscription information for details.

To back up files and folders:
1. Start Acronis True Image 2021. 2. On the sidebar, click Backup. 3. Click the Backup source icon, and then select Files and folders. 4. In the opened window, select the check boxes next to the files and folders that you want to back
up, and then click OK. 5. Click the Backup destination icon, and then select a destination for backup:
 Acronis Cloud--Sign in to your Acronis account, and then click OK.  Your external drive--When an external drive is plugged into your computer, you can select it
from the list.

23

Copyright © Acronis International GmbH, 2003-2020

 NAS--Select an NAS from the list of found NAS devices. If you have only one NAS, Acronis True Image 2021 will suggest using it as a backup destination by default.
 Browse--Select a destination from the folder tree. 6. Click Back up now.
Refer to Backing up files and folders (p. 47) for details.
Additionally, watch the English-language video instructions at https://goo.gl/i4J1AN.
2.6 Cloning your hard drive
Why do I need it?
When you see that the free space on your hard drive is not enough for your data, you might want to buy a new, larger hard drive and transfer all your data to the new drive. The usual copy operation does not make your new hard drive identical to the old one. For example, if you open File Explorer and copy all files and folders to the new hard drive, Windows will not start from the new hard drive. The Clone disk utility allows you to duplicate all your data and make Windows bootable on your new hard drive.

Before you start
We recommend that you install the target (new) drive where you plan to use it and the source drive in another location, for example, in an external USB enclosure. This is especially important for laptops.
Note: It is recommended that your old and new hard drives work in the same controller mode (for example, IDE or AHCI). Otherwise, your computer might not start from the new hard drive.
Using the Clone disk utility
To clone a disk:
1. On the sidebar, click Tools, and then click Clone disk. 2. On the Clone Mode step, we recommend that you choose the Automatic transfer mode. In this
case, the partitions will be proportionally resized to fit your new hard drive. The Manual mode provides more flexibility. Refer to Clone Disk wizard (p. 138) for more details about the manual mode.

24

Copyright © Acronis International GmbH, 2003-2020

If the program finds two disks, one partitioned and another unpartitioned, it will automatically recognize the partitioned disk as the source disk and the unpartitioned disk as the destination disk. In this case, the next steps will be bypassed and you will be taken to the cloning Summary screen.
3. On the Source Disk step, select the disk that you want to clone.

4. On the Destination Disk step, select the destination disk for the cloned data.
If any disk is unpartitioned, the program will automatically recognize it as the destination and bypass this step.
5. On the Finish step, ensure that the configured settings suit your needs, and then click Proceed.
By default, Acronis True Image 2021 shuts down the computer after the clone process finishes. This enables you to change the position of master/subordinate jumpers and remove one of the hard drives.
Additionally, watch the English-language video instructions at https://goo.gl/bjWRLL (https://goo.gl/bjWRLL).
2.7 Recovering your computer
Please be aware that recovery of a system disk is an important operation. Before you start, we recommend that you read the detailed descriptions in the following Help topics:  Trying to determine the crash cause (p. 88)  Preparing for recovery (p. 88)  Recovering your system to the same disk (p. 89) Let's consider two different cases: 1. Windows works incorrectly, but you can start Acronis True Image 2021. 2. Windows cannot start (for example, you turn on your computer and see something unusual on

3.1 Basic concepts
This section provides general information about basic concepts which could be useful for understanding how the program works.
Backup and recovery
Backup refers to the making copies of data so that these additional copies may be used to recover the original after a data loss event.
Backups are useful primarily for two purposes:  To recover an operating system when it is corrupted or cannot start (called disaster recovery).
Refer to Protecting your system (p. 17) for more details about protecting your computer from a disaster.  To recover specific files and folders after they have been accidentally deleted or corrupted.
Acronis True Image 2021 does both by creating disk (or partition) images and file-level backups respectively.
Recovery methods:  Full recovery can be performed to the original location or to a new one.
When the original location is selected, the data in the location is completely overwritten with the data from the backup. In case of a new location, the data is just copied to the new location from the backup.  Incremental recovery is performed only to the original location and only from a cloud backup. Before the recovery starts, the files in the original location are compared with the files in the backup by file attributes, such as file size and date of last modification. Those files that do not match are marked for recovery, the remaining files will be skipped during recovery. In that way, as opposed to the full recovery, Acronis True Image recovers only changed files. This method significantly reduces the recovery time and saves Internet traffic while recovering from Acronis Cloud.
Backup versions
Backup versions are the file or files created during each backup operation. The number of versions created is equal to the number of times the backup is executed. So, a version represents a point in time to which the system or data can be restored.

Backup versions represent full, incremental and differential backups - see Full, incremental and differential backups (p. 33).
The backup versions are similar to file versions. The file versions concept is familiar to those who use a Windows feature called "Previous versions of files". This feature allows you to restore a file as it existed on a particular date and time. A backup version allows you to recover your data in a similar way.
Disk cloning
This operation copies the entire contents of one disk drive to another disk drive. This may be necessary, for example, when you want to clone your operating system, applications, and data to a new larger capacity disk. You can do it two ways:  Use the Clone disk utility.  Back up your old disk drive, and then recover it to the new one.
Backup file format
Acronis True Image usually saves backup data in the proprietary tib format using compression. The data from .tib file backups can be recovered only through Acronis True Image, in Windows or in the recovery environment.
Acronis Nonstop Backup uses a special hidden storage for data and metadata. The backed up data is compressed and split into files of about 1 GB. These files also have a proprietary format and the data they contain can be recovered only with the help of Acronis True Image.
Backup validation
The backup validation feature allows you to confirm that your data can be recovered. The program adds checksum values to the data blocks being backed up. During backup validation, Acronis True Image opens the backup file, recalculates the checksum values and compares those values with the stored ones. If all compared values match, the backup file is not corrupted.
Scheduling
For your backups to be really helpful, they must be as "up-to-date" as possible. Schedule your backups to run automatically and on a regular basis.
Deleting backups
When you want to delete backups and backup versions you no longer need, please do it by using the tools provided by Acronis True Image 2021. Refer to Deleting backups and backup versions (p. 83) for details.
Acronis True Image 2021 stores information on the backups in a metadata information database. Therefore, deleting unneeded backup files in File Explorer will not delete information about these backups from the database. This will result in errors when the program tries to perform operations on the backups that no longer exist.
3.2 The difference between file backups and disk/partition images
When you back up files and folders, only the files and folder tree are compressed and stored.

31

Copyright © Acronis International GmbH, 2003-2020

Disk/partition backups are different from file and folder backups. Acronis True Image 2021 stores an exact snapshot of the disk or partition. This procedure is called "creating a disk image" or "creating a disk backup" and the resulting backup is often called "a disk/partition image" or "a disk/partition backup".
What does a disk/partition backup contain?
A disk/partition backup contains all the data stored on the disk or partition:
1. Zero track of the hard disk with the master boot record (MBR) (applicable to MBR disk backups only).
2. One or more partitions, including: 1. Boot code. 2. File system meta data, including service files, file allocation table (FAT), and partition boot record. 3. File system data, including operating system (system files, registry, drivers), user data and software applications.
3. System Reserved partition, if any. 4. EFI system partition, if any (applicable to GPT disk backups only).
What is excluded from disk backups?
To reduce image size and speed up image creation, by default Acronis True Image 2021 only stores the hard disk sectors that contain data.
Acronis True Image 2021 excludes the following files from a disk backup:  pagefile.sys  hiberfil.sys (a file that keeps RAM contents when the computer goes into hibernation)
You can change this default method by turning on the sector-by-sector mode. In this case, Acronis True Image 2021 copies all hard disk sectors, and not only those that contain data.
Additionally, when you back up your system partition or disk to Acronis Cloud, Acronis True Image excludes the following data:  The Temp folders, usually located in:
 C:\Windows\Temp\  C:\Users\<username>\AppData\Local\Temp  The System Volume Information folder (usually located in C:\System Volume Information\)  The Recycle Bin  Web browser temporary data:  Temporary Internet files  Cookies  History  Cache  .tib and .tibx files  .tmp files  .~ files

32

3.3 Full, incremental and differential backups
Acronis True Image 2021 offers three backup methods: full, incremental, and differential.
Full method
The result of a full method backup operation (also known as full backup version) contains all of the data at the moment of the backup creation.
Example: Every day, you write one page of your document and back it up using the full method. Acronis True Image saves the entire document every time you run backup. 1.tibx, 2.tibx, 3.tibx, 4.tibx--files of full backup versions.

Additional information
A full backup version forms a base for further incremental or differential backups. It can also be used as a standalone backup. A standalone full backup might be an optimal solution if you often roll back the system to its initial state or if you do not like to manage multiple backup versions.
Recovery: In the example above, to recover the entire work from the 4.tibx file, you need to have only one backup version--4.tib.
Incremental method
The result of an incremental method backup operation (also known as incremental backup version) contains only those files which have been changed since the LAST BACKUP.
Example: Every day, you write one page of your document and back it up using the incremental method. Acronis True Image saves the new page every time you run backup.
Note: The first backup version you create always uses full method.  1.tibx--file of full backup version.

33

Copyright © Acronis International GmbH, 2003-2020

 2.tibx, 3.tibx, 4.tibx--files of incremental backup versions.

Additional information
Incremental method is the most useful when you need frequent backup versions and the ability to roll back to a specific point in time. As a rule, incremental backup versions are considerably smaller than full or differential versions. On the other hand, incremental versions require more work for the program to provide recovery.
Recovery: In the example above, to recover the entire work from the 4.tibx file, you need to have all the backup versions--1.tibx, 2.tibx, 3.tibx, and 4.tibx. Therefore, if you lose an incremental backup version or it becomes corrupted, all later incremental versions are unusable.
Differential method
The result of a differential method backup operation (also known as differential backup version) contains only those files which have been changed since the LAST FULL BACKUP.
Example: Every day, you write one page of your document and back it up using the differential method. Acronis True Image saves the entire document except the first page stored in the full backup version.
Note: The first backup version you create always uses full method.  1.tibx--file of full backup version.

34

Copyright © Acronis International GmbH, 2003-2020

 2.tibx, 3.tibx, 4.tibx--files of differential backup versions.

Additional information
Differential method is an intermediate between the first two approaches. It takes less time and space than "Full", but more than "Incremental". To recover data from a differential backup version, Acronis True Image needs only the differential version and the last full version. Therefore, recovery from a differential version is simpler and more reliable than recovery from an incremental one.
Recovery: In the example above, to recover the entire work from the 4.tibx file, you need to have two backup versions--1.tibx and 4.tibx.
To choose a desired backup method, you usually need to configure a custom backup scheme. For more information see Custom schemes (p. 60).
An incremental or differential backup created after a disk is defragmented might be considerably larger than usual. This is because the defragmentation program changes file locations on the disk and the backups reflect these changes. Therefore, it is recommended that you re-create a full backup after disk defragmentation.
Changed Block Tracker (CBT)
The CBT technology accelerates the backup process when creating local incremental or differential disk-level backup versions. Changes to the disk content are continuously tracked at the block level. When a backup starts, the changes can be immediately saved to the backup.
3.4 Deciding where to store your backups
Acronis True Image 2021 supports quite a few of storage devices. For more information, refer to Supported storage media.
The table below shows possible backup destinations for your data.

Though backing up to your local hard drive is the simplest option, we recommend that you store your backups off-site because it enhances the security of your data.

Recommended storage media:
1. Acronis Cloud 2. External drive
If you plan to use an external USB hard drive with your desktop PC, we recommend that you connect the drive to a rear connector by using a short cable. 3. Home file server, NAS, or NDAS Please check whether Acronis True Image 2021 detects the selected backup storage, both in Windows and when booted from the bootable media. To gain access to an NDAS-enabled storage device, in many cases you will need to specify the NDAS device ID (20 characters) and the write key (five characters). The write key allows you to use an NDAS-enabled device in write mode (for example, for saving your backups). Usually the device ID and write key are printed on a sticker attached to the bottom of the NDAS device or on the inside of its enclosure. If there is no sticker, you need to contact your NDAS device vendor to obtain that information. 4. Network share See also: Authentication settings (p. 37). 5. FTP server See also: FTP connection (p. 37). 6. Optical discs (CD, DVD, BD) Blank optical discs such as DVD-R, DVD+R are very cheap, so they will be the lowest cost solution for backing up your data, though the slowest one. Due to the necessity of swapping discs, we strongly recommend to avoid backing up to DVDs if the number of discs is more than three. When there is no alternative to backing up to DVDs, we recommend to copy all DVDs to a folder on a hard disk, and then to recover from that folder.

3.4.1 Preparing a new disk for backup
A new internal or external hard drive may not be recognized by Acronis True Image 2021. If this is the case, use the operating system tools to change the disk status to Online and then to initialize the disk.
To change a disk status to Online:

36

Copyright © Acronis International GmbH, 2003-2020

1. Open Disk Management. To do this, go to Control Panel -> System and Security -> Administrative Tool, start Computer Management, and then click Disk Management.
2. Find the disk marked as Offline. Right-click the disk and then click Online. 3. The disk status will be changed to Online. After that, you will be able to initialize the disk.
To initialize a disk:
1. Open Disk Management. To do this, go to Control Panel -> System and Security -> Administrative Tool, start Computer Management, and then click Disk Management.
2. Find the disk marked as Not Initialized. Right-click the disk and then click Initialize Disk. 3. Select a partition table for the disk - MBR or GPT, and then click OK. 4. [optional step] To create a volume on the disk, right-click the disk, click New Simple Volume, and
then follow the wizard's steps to configure the new volume. To create one more volume, repeat this operation.
3.4.2 FTP connection
Acronis True Image 2021 allows you to store your backups on FTP servers.
To create a new FTP connection, when selecting a backup storage click FTP connection, and in the opened window provide:  Path to the FTP server, for example: my.server.com  Port  User name  Password
To check your settings, click the Test connection button. The computer will try to connect to the specified FTP server. If the test connection has been established, click the Connect button to add the FTP connection.
The created FTP connection will appear in the folder tree. Select the connection and browse for the backup storage that you want to use.
Please, be aware that the mere opening of an FTP server's root folder does not bring you to your home directory.
Acronis True Image 2021 splits a backup into files with a size of 2GB when backing up directly to an FTP server. If you back up to a hard disk with the aim of transferring the backup to an FTP later, split the backup into files of 2GB each by setting the desired file size in the backup options. Otherwise, the recovery will not be possible.
An FTP server must allow passive mode file transfers.
The firewall settings of the source computer should have Ports 20 and 21 opened for the TCP and UDP protocols to function. The Routing and Remote Access Windows service should be disabled.
3.4.3 Authentication settings
If you are connecting to a networked computer, in most cases you will need to provide the necessary credentials for accessing the network share. For example, this is possible when you select a backup storage. The Authentication Settings window appears automatically when you select a networked computer name.
If necessary, specify the user name and password, and then click Test connection. When the test is successfully passed, click Connect.

37

Troubleshooting
When you create a network share that you plan to use as a backup storage, please ensure that at least one of the following conditions is met:  Windows account has a password on the computer where the shared folder is located.  Password-protected sharing is turned off in Windows.
You can find this setting at Control Panel --> Network and Internet --> Network and Sharing Center --> Advanced sharing settings --> Turn off password protected sharing.
Otherwise, you will not be able to connect to the shared folder.
3.5 Using Acronis Nonstop Backup
Acronis Nonstop Backup provides easy protection of your disks and files. It allows you to recover entire disks, individual files and their different versions.
The main purpose of Acronis Nonstop Backup is continuous protection of your data (files, folders, contacts, etc.), though you can use it to protect partitions as well. If you choose to protect an entire partition, you will be able to recover the partition as a whole using the image recovery procedure.
We do not recommend using nonstop backup as a primary way to protect your system. For the safety of your system, use any other schedule. Refer to Examples of custom schemes (p. 62) for examples and details.
Nonstop Backup limitations  You can create only one nonstop backup.  Acronis Cloud cannot be used as a destination for a disk-level nonstop backup.  Windows libraries (Documents, Music, etc.) can be protected with a disk-level nonstop backup
only.  You cannot protect data stored on external hard drives.  Nonstop Backup and Try&Decide cannot work simultaneously.
How it works
Once you start Acronis Nonstop Backup, the program will perform an initial full backup of the data selected for protection. Acronis Nonstop Backup will then continually monitor the protected files (including open ones). Once a modification is detected, the changed data is backed up. The shortest interval between the incremental backup operations is five minutes. This allows you to recover your system to an exact point in time.
Acronis Nonstop Backup checks file changes on the disk, not in the memory. If, for instance, you are working in Word and do not use the "Save" operation for a long time, your current changes in the Word document will not be backed up.
You may think that at these backup rates the storage will fill in no time. Do not worry as Acronis True Image 2021 will back up only so called "deltas". This means that only differences between old and new versions will be backed up and not whole changed files. For example, if you use Microsoft Outlook or Windows Mail, your pst file may be very large. Furthermore, it changes with each received or sent E-mail message. Backing up the entire pst file after each change would be an unacceptable waste of your storage space, so Acronis True Image 2021 backs up only its changed parts in addition to the initially backed up file.

38

Retention rules
Local backups
Acronis Nonstop Backup keeps all backups for the last 24 hours. The older backups will be consolidated in such a way that Nonstop Backup will keep daily backups for the last 30 days and weekly backups until all Nonstop Backup data destination space is used.
The consolidation will be performed every day between midnight and 01:00 AM. The first consolidation will take place after the Nonstop Backup has been working for at least 24 hours. For example, you have turned on the Nonstop Backup at 10:00 AM on July 12. In this case the first consolidation will be performed between 00:00 and 01:00 AM on July 14. Then the program will consolidate the data every day at the same time. If your computer is turned off between 00:00 and 01:00 AM, the consolidation will start when you turn the computer on. If you turn off Nonstop Backup for some time, the consolidation will start after you turn it on again.
Cloud backups
Acronis True Image 2021 keeps only the following backup versions:  All versions for the last hour  The first versions of every hour for the last 24 hours  The first version of every day for the last week  The first version of every week for the last month  The first version of every month
All other versions are automatically deleted. The retention rules are pre-set and cannot be changed.
3.5.1 Acronis Nonstop Backup data storage
Acronis Nonstop Backup data storage can be created on local hard disk drives (both internal and external) or Acronis Cloud.
In many cases an external hard disk will be the best choice for Nonstop Backup data storage. You can use an external disk with any of the following interfaces: USB (including USB 3.0), eSATA, FireWire, and SCSI.
You can also use an NAS as the storage, but with one limitation - it must be accessible with the SMB protocol. It does not matter whether an NAS share you want to use for the storage is mapped as a local disk or not. If the share requires login, you will need to provide the correct user name and password. For more information see Authentication settings (p. 37). Acronis True Image 2021 remembers the credentials and the subsequent connections to the share do not require login.
When an external hard disk or NAS is unavailable, the Nonstop Backup destination can be an internal disk, including a dynamic one. Please note that you cannot use a partition to be protected as a Nonstop Backup storage. If your computer has a single hard disk drive with a single partition, but you want to use Acronis Nonstop Backup anyway, you can create Acronis Secure Zone and use it as the Nonstop Backup data storage.
Before creating Acronis Nonstop Backup data storage, Acronis True Image 2021 checks whether the selected destination has enough free space. It multiplies the volume of data to be protected by 1.2 and compares the calculated value with the available space. If the free space on the destination satisfies this minimum storage size criterion, the destination can be used for storing Nonstop Backup data.

3.5.2 Nonstop Backup - Frequently asked questions
Why does Acronis Nonstop Backup pause on its own? - This is the designed behavior of Acronis Nonstop Backup. When the system load rises to a critical level, Acronis Nonstop Backup receives the overload alarm from Windows and pauses itself. This is done to aid Windows relieve the load caused by other applications. The overload can be caused by running resource-intensive applications (for example, performing a deep system scan with your antivirus software).
In such a case Nonstop Backup automatically pauses and you cannot restart it. After pausing, Acronis Nonstop Backup gives the system one hour to relieve the load and then attempts to restart.
The automatic restart count for Acronis Nonstop Backup is 6. This means that after the first automatic restart Acronis Nonstop Backup will attempt to restart five more times with intervals of exactly one hour between attempts.
After the sixth unsuccessful attempt, Acronis Nonstop Backup will wait for the next calendar day. On the next day the automatic restart count will automatically reset. When not interfered with, Acronis Nonstop Backup performs six restart attempts per day.
The restart attempt count can be reset by doing any of the following:  Restarting Acronis Nonstop Backup service;  Rebooting the computer.
Restarting Acronis Nonstop Backup service will only reset the restart count to 0. If the system is still overloaded, Acronis Nonstop Backup will pause again. An Acronis Support Knowledge Base article at https://kb.acronis.com/content/14708 describes the procedure for restarting the Acronis Nonstop Backup service.
Rebooting the computer will reset the load and the restart count. If the system overloads again, Acronis Nonstop Backup will pause.
Why does Acronis Nonstop Backup sometimes cause a high CPU load? - This is the expected behavior of Acronis Nonstop Backup. This may happen on restart of a paused Acronis Nonstop Backup if a considerable amount of protected data has been modified during the pause.
For example, if you manually pause the Acronis Nonstop Backup that you use for protecting your system partition and then install a new application. When you restart Acronis Nonstop Backup, it loads the CPU for some time. However, the process (afcdpsrv.exe) then goes back to normal.
This happens because Acronis Nonstop Backup needs to check the backed up data against the data that have been modified during the pause to ensure protection continuity. If there was a considerable amount of data modified, the process may load CPU for some time. After the check is done and all the modified data is backed up, Acronis Nonstop Backup goes back to normal.
Can I have Acronis Nonstop Backup storage on an FAT32 partition of a local hard disk? - Yes, FAT32 and NTFS partitions can be used as the storage.
Can I set up Acronis Nonstop Backup storage on a network share or NAS? - Yes, Acronis Nonstop Backup supports network shares, mapped drives, NAS and other network attached devices with one limitation - they must use the SMB protocol.
3.6 Backup file naming
Depending on the version by which a backup was created, its name will differ.

40

Copyright © Acronis International GmbH, 2003-2020

Naming convention for backup files created by Acronis True Image 2020 or higher
A backup file name has only the backup name and an incremental counter. It does not contain any additional information such as backup method, backup chain number, backup version number, or volume number.
A backup name may look like:
1. my_documents.tibx 2. my_documents_0001.tibx 3. my_documents_0002.tibx 4. my_documents_0003.tibx
Full and differential backups are stored in separate files and incremental backups are automatically merged into full backups.
The following backups continue to use the TIB format and naming convention:  File-level backups for all destinations except for Acronis Cloud. File-level backups to Acronis
Cloud are in .tibx format.  Nonstop backups  Notarized backups  Backups which use CD/DVD/Blu-ray, FTP, or Acronis Secure Zone as their destination
Naming convention for backup files created before Acronis True Image 2020
A backup file name has the following attributes:  Backup name  Backup method (full, inc, diff: full, incremental, differential)  Number of backup chain (p. 197) (in the form of b#)  Number of backup (p. 197)version (p. 197)(in the form of s#)  Number of volume (in the form of v#)
For example this attribute changes when you split a backup into several files. Refer to Backup splitting (p. 69) for details.
Thus a backup name may look the following way:
1. my_documents_full_b1_s1_v1.tib 2. my_documents_full_b2_s1_v1.tib 3. my_documents_inc_b2_s2_v1.tib 4. my_documents_inc_b2_s3_v1.tib
If you are creating a new backup, and there is already a file with the same name, the program does not delete the old file, but adds to the new file the "-number" suffix, for example, my_documents_inc_b2_s2_v1-2.tib.

3.7 Integration with Windows
During installation Acronis True Image 2021 provides closer integration with Windows. Such merging allows you to get the most out of your computer.

Tray Notification Center
When Acronis True Image 2021 is open, you can see the status of any operation in it. However, since some operations can take quite a while, such as a backup, there is no need to keep Acronis True Image 2021 to learn its result.
The Tray Notification Center contains latest notifications in one place, lets you see important operation statuses without opening Acronis True Image 2021 at the moment when you need them. The following notifications are shown in Acronis Tray Notification Center: personal offers, information on the results of backup operations, and other important notifications from True Image. The Tray Notification Center is minimized and hidden under Acronis True Image 2021 in the tray.
Shortcut menu commands
To access shortcut menu commands, open File Explorer, right-click selected items, point to Acronis True Image, and then select a command.  To create a new file-level backup, select New file backup.  To create a new disk-level backup, select New disk backup.  To mount a disk-level backup (.tib file), select Mount.  To validate a backup (.tib file), select Validate.
File-level recovery in File Explorer
To recover files and folders: 1. In File Explorer, double-click the backup file (.tib file) that contains the data to recover. 2. Copy or drag the files and folders to any location on your computer, as if they were stored on an
ordinary disk.
3.8 Wizards
When you use the available Acronis True Image 2021 tools and utilities, the program will in many cases employ wizards to guide you through the operations.

42

Copyright © Acronis International GmbH, 2003-2020

settings.



Columns - allows you to choose which table columns to display and in which order.

3. This is the main area where you select items and change settings.

4. This area displays additional information about the item you select in area 3.

3.9 FAQ about backup, recovery and cloning
 I have a 150GB system partition, but the occupied space on that partition is only 80GB. What will Acronis True Image 2021 include in a backup? - By default, Acronis True Image 2021 copies only the hard disk sectors that contain data, so it will include only 80GB in a backup. You can also choose the sector-by-sector mode. Note than such a backup mode is required only in special cases. For more information, see Image creation mode (p. 67). While creating a sector-by-sector backup, the program copies both used and unused hard disk sectors and the backup file will usually be significantly larger.
 Will my system disk backup include drivers, documents, pictures, etc.? - Yes, such a backup will contain the drivers, as well as the contents of the My documents folder and its subfolders, if you

43

Copyright © Acronis International GmbH, 2003-2020

kept the default location of the My documents folder. If you have just a single hard disk in your PC, such a backup will contain all of the operating system, applications and data.  I have an old hard disk drive which is almost full in my notebook. I purchased a new bigger HDD. How can I transfer Windows, programs and data to the new disk? - You can either clone the old hard disk on the new one or back up the old hard disk and then recover the backup to a new one. The optimum method usually depends on your old hard disk partitions layout.  I want to migrate my old system hard disk to an SSD. Can this be done with Acronis True Image 2021? - Yes, Acronis True Image 2021 provides such a function. For procedure details, see Migrating your system from an HDD to an SSD (p. 143)  What is the best way to migrate the system to a new disk: cloning or backup and recovery? The backup and recovery method provides more flexibility. In any case, we strongly recommend to make a backup of your old hard disk even if you decide to use cloning. It could be your data saver if something goes wrong with your original hard disk during cloning. For example, there were cases when users chose the wrong disk as the target and thus wiped their system disk. In addition, you can make more than one backup to create redundancy and increase security.  What should I back up: a partition or the whole disk? - In most cases, it is better to back up the whole disk. However, there may be some cases when a partition backup is advisable. For example, your notebook has a single hard disk with two partitions: system (disk letter C) and the data (disk letter D). The system partition stores your working documents in the My documents folder with subfolders. The data partition stores your videos, pictures, and music files. Such files are already compressed and backing them up using Acronis True Image 2021 would not give you significant reduction of the backup file size. However, we recommend creating at least one whole disk backup if your backup storage has enough space.  Could you tell me how to clone: in Windows or after booting from the Acronis bootable media? Even when you start cloning in Windows, the computer will reboot into the Linux environment the same as when booting from the Acronis bootable media. Because of this, it is better to clone under Acronis bootable media. For example, there may be a case when your hard disk drives are detected in Windows and not detected in Linux. If this is the case, the cloning operation will fail after reboot. When booting from the bootable media, you can make sure that Acronis True Image 2021 detects both the source and target disks before starting the cloning operation.  Can I clone or back up and recover a dual boot machine? Yes, this is possible when both operating systems are Windows. If your systems are installed in separate partitions of the same physical hard disk drive, cloning or recovery usually proceeds without any problems. If the systems are on different physical hard disk drives, there may be some problems with bootability after recovery.  Does Acronis True Image 2021 support RAID? - Acronis True Image 2021 supports hardware RAID arrays of all popular types. Support of software RAID configurations on dynamic disks is also provided. Acronis bootable media supports most of the popular hardware RAID controllers. If the standard Acronis bootable media does not "see" the RAID as a single volume, the media does not have the appropriate drivers. In this case you can try to create WinPE-based media. This media may provide the necessary drivers.

In this section Backing up disks and partitions......................................................................................... 45 Backing up files and folders .............................................................................................. 47 Backing up mobile devices ................................................................................................ 52 Backing up Office 365 data ............................................................................................... 54 Backup options.................................................................................................................. 55 Operations with backups .................................................................................................. 78
4.1 Backing up disks and partitions
As opposed to file backups, disk and partition backups contain all the data stored on the disk or partition. This backup type is usually used to create an exact copy of a system partition of the whole system disk. Such backup allows you to recover your computer when Windows works incorrectly or cannot start.
To back up partitions or disks:
1. Start Acronis True Image 2021. 2. On the sidebar, click Backup. 3. Click Add backup. 4. [Optional] To rename the backup, click the arrow next to the backup name, click Rename, and
then enter a new name. 5. Click the Backup source area, and then select Disks and partitions. 6. In the opened window, select the check boxes next to the partitions and disks that you want to
back up, and then click OK. To view hidden partitions, click Full partition list.

45

To back up dynamic disks you can use only the partition mode.

7. Click the Backup destination area, and then select a destination for backup:  Acronis Cloud--Sign in to your Acronis account, and then click OK. If you do not have an Acronis account, click Create account, type your email address, password, and then click the Create account button. Refer to Acronis account (p. 27) for details.  Your external drive--When an external drive is plugged into your computer, you can select it from the list.  NAS--Select an NAS from the list of found NAS devices. If you have only one NAS, Acronis True Image 2021 will suggest using it as a backup destination by default.  Browse--Select a destination from the folder tree.
If possible, avoid storing your system partition backups on dynamic disks, because the system partition is recovered in the Linux environment. Linux and Windows work with dynamic disks differently. This may result in problems during recovery.
8. [optional step] Click Options to set the options for the backup, including Schedule (p. 55), Scheme (p. 58), and Password protection (p. 67). For more information see Backup options (p. 55).

4.2.1.1 Using Blockchain technology
Acronis True Image 2021 uses the Blockchain technology to provide top-level security for your backed-up files. This technology gives you the guarantee that your files have not been modified by fraudulent software, and when it is time to recover, you recover data from exactly the same file that was backed up.
What is Blockchain?
Blockchain is a database that contains information about transactions and their sequence. In general, a transaction represents an event, such as a financial operation or an operation with different kinds of assets. The transactions are united in blocks, which are written to the database one by one and form a block chain. Every transaction and every block has its own unique identification number. What is very important is that every block stores information about all previous blocks of the chain. Once written to the database, the information about a transaction cannot be changed in any way or by anyone, and the transaction sequence cannot be modified either. Any attempt to change any piece of information in the database can be easily identified by any user of the database, because there would be no information about the false transaction or false block in all subsequent blocks. This technology guarantees that data stored in the database is valid, belongs to a specific person, and has not been modified by anyone. See more information about Blockchain at https://en.wikipedia.org/wiki/Blockchain_(database).
How Acronis True Image 2021 uses the Blockchain technology
To protect your files from unauthorized modification, Acronis True Image 2021 uses the Acronis Notary technology. This is a universal solution for timestamping and fingerprinting any data objects and streams. Since it is impractical to store large amount of data in a Blockchain database, Acronis True Image 2021 sends only file hash codes to the Acronis Notary service.
A hash code is a unique number of fixed size that is produced by a hash function. The code mathematically defines an arbitrary set of data, for example, a backup file. Any change of the backup file leads to a change of its hash code. Therefore, to check if the file was changed, you only need to compare the hash codes generated in the initial and current states of the file. If the codes match, this is a guarantee that the file has not been modified by anyone.
When Acronis Notary receives hash codes of your files, it calculates a new single hash code and sends it to the Ethereum Blockchain-based database. See more information about Ethereum at https://www.ethereum.org/.
Once the hash code is in the database, the files that were used to calculate this hash code are notarized by Acronis Notary. You can easily verify the file authenticity at any time by using the procedure described in Verifying file authenticity (p. 50). Every notarized file has a notarization certificate, which is documentary proof that the file is protected with the Blockchain technology. A certificate contains general information about the file and technical details that allow you to manually verify the file authenticity. Refer to Manual verification of a file's authenticity (p. 51) for details.

4.2.1.2 Verifying file authenticity
By using Blockchain technology, Acronis True Image 2021 can protect your backed-up files from unauthorized modification. This gives you a guarantee that you can recover data from exactly the same file that was backed up.

To verify a file's authenticity on Acronis Cloud:
1. Go to https://www.acronis.com/my/online-backup/webrestore/, and then log in to your Acronis account.
2. Browse to the required file, click on the file name, and then click the Verify or Get certificate on the side bar. See the commands description above.
4.2.1.3 Manual verification of a file's authenticity
The easiest way to verify a file's authenticity is to use the Verify command in Acronis True Image 2021 or in the Acronis Cloud web application. Refer to Verifying file authenticity (p. 50) for details. In addition to this easy method, you can perform the verification procedure yourself, step by step.
To verify a file's authenticity manually:
Step 1. Calculate MD5 hash of the file
1. Start Windows PowerShell. 2. For example, to calculate the md5 hash for the picture.png file located in C:\Users\picture.png,
type:
$($(CertUtil -hashfile "C:\Users\picture.png" MD5)[1] -replace " ","")
Example of an md5 hash: eea16ade1edf2750a46bb6bffb2e45a2 3. Check that the calculated md5 hash is equal to an eTag in the DATA field in your notarization
certificate. Refer to Verifying file authenticity (p. 50) for details about obtaining a file certificate.
Step 2. Check that a ROOT is stored in the blockchain
1. Open a blockchain explorer, for example https://etherscan.io/. 2. Enter the TRANSACTION ID from the certificate into the search field. 3. Check that the Data field in the Event Logs tab is equal to the ROOT value in your certificate.

Step 3. Check that the hash is included in the tree
1. Download the command line utility from the GitHub repository: https://github.com/acronis/notary-verifyhash/releases.
2. Follow the instructions at: https://github.com/acronis/notary-verifyhash.
4.2.1.4 Acronis ASign
What is Acronis ASign?
Acronis ASign is an online-service that allows multiple people to sign a file electronically. The file should be preliminarily uploaded to Acronis Cloud via backup, archiving, or sync. To further protect the signed files, they are notarized and protected via Acronis Notary.
The ASign solution can be used for signing any electronic documents, including different kinds of contracts, agreements, certificates, financial documents, and official letters.

Note that Windows should recognize this device as external.  User logon ­ the operation will be executed each time the current user logs on to the OS.  User logoff ­ the operation will be executed each time the current user logs off the OS.  System startup with delay (in minutes) ­ the operation will be executed at every OS startup with the delay time you specified.  System shutdown or restart ­ the operation will be executed at every computer shutdown or reboot.
 Additional condition  If you want to run an operation only at the first occurrence of the event on the current day, select the Once a day only check box.
Description of the Advanced settings see in Scheduling (p. 55).
4.5.2 Backup schemes
Location: Options > Backup scheme
Backup schemes along with the scheduler help you set up your backup strategy. The schemes allow you to optimize backup storage space usage, improve data storage reliability, and automatically delete the obsolete backup versions.
For online backups, the backup scheme is preset and cannot be changed. After the initial full backup, only incremental versions are created.
The backup scheme defines the following parameters:  Backup methods (p. 33) that will be used to create backup versions (full, differential or
incremental)  Sequence of the backup versions created using different methods

58

Copyright © Acronis International GmbH, 2003-2020

 Version cleanup rules

Acronis True Image 2021 allows you to choose from the following backup schemes:  Single version (p. 59) - select this scheme if you want to use the smallest backup storage.  Version chain (p. 60) - this may be the optimal scheme in many cases.  Incremental - select to create a full version after every five incremental versions. This is the
default scheme.  Differential - select to create only differential backups after an initial full backup.  Custom (p. 60) - select to set up a backup scheme manually.
You can easily change the backup scheme for a pre-existing backup. This will not affect the integrity of the backup chains, so you will be able to recover your data from any previous backup version.
You cannot change the backup scheme when backing up to optical media such as a DVD/BD. In this case, Acronis True Image 2021 by default uses a custom scheme with only full backups. This is because the program cannot consolidate backups stored on optical media.
4.5.2.1 Single version scheme
This backup scheme is the same for both disk backup and file backup types (except scheduler settings).
The program creates a full backup version and overwrites it every time according to the specified schedule or when you run the backup manually. In this process, the old version is deleted only after a new version is created.
For backups created in Acronis True Image 2020 or later, the very first file will remain for auxiliary purposes, without your data in it. Please do not delete it!
Backup scheduler setting for disk backup: monthly.

59

Copyright © Acronis International GmbH, 2003-2020

Backup scheduler setting for file backup: daily.
Result: you have a single up-to-date full backup version.
Required storage space: minimal.
4.5.2.2 Version chain scheme
This backup scheme differs for disk backup and file backup types.
Disk backup version chain
At first the program creates the 1st full backup version. The version will be kept until you delete it manually. After that, according to the specified schedule (or when you run backup manually) the program creates: 1 full and 5 differential backup versions, then again 1 full and 5 differential backup versions and so on. The versions will be stored for 6 months. After the period the program analyzes if the oldest backup versions (except the 1st full version) may be deleted. It depends on the minimum number of versions (eight) and version chains consistency. The program deletes the oldest versions one by one after creating new versions with the same backup method (for example, the oldest differential version will be deleted after creation of the newest differential version). First of all the oldest differential versions will be deleted, then - the oldest full version.
Backup scheduler setting: monthly.
Result: you have monthly backup versions for the last 6 months plus the initial full backup version that may be kept for a longer period.
Required storage space: depends on the number of versions and their sizes.
File backup version chain
According to the specified schedule (or when you run backup manually) the program creates: 1 full and 6 incremental backup versions, then again 1 full and 6 incremental versions and so on. The versions will be stored for 1 month. After the period the program analyzes if the oldest backup versions may be deleted. It depends on the version chain consistency. To keep the consistency, the program deletes the oldest versions by chains "1 full + 6 incremental backup versions" after creating a new analogous version chain.
Backup scheduler setting: daily.
Result: you have backup versions for every day of the last month.
Required storage space: depends on the number of versions and their sizes.
4.5.2.3 Custom schemes
With Acronis True Image 2021 you also can create your own backup schemes. Schemes can be based on the pre-defined backup schemes. You can make changes in a selected pre-defined scheme to suit your needs and then save the changed scheme as a new one.
You cannot overwrite existing pre-defined backup schemes.
In addition, you can create custom schemes from scratch based on full, differential or incremental backup versions.
So first of all select one of the backup methods in the appropriate box.

 Full (p. 33) Select this method if you want to create only full backup versions.
 Differential (p. 33)
Select this method if you want to create backup chains containing only full and differential backup versions.
You can configure the scheme by using one of the following options:  Create only differential versions after the initial full version - select this item to create only
one backup version chain. Automatic cleanup is not available for this option.  Create a full version after every [n] differential versions - select this item to create several
backup version chains. This is a more reliable but more space-consuming backup scheme.  Incremental (p. 33)
Select this method if you want to create backup chains containing only full and incremental backup versions.
You can configure the scheme by using one of the following options:  Create only incremental versions after the initial full version - select this item to create only
one backup version chain. Automatic cleanup is not available for this option.  Create a full version after every [n] incremental versions - select this item to create several
backup version chains. This is a more reliable but more space-consuming backup scheme.
Automatic cleanup rules
To delete obsolete backup versions automatically, you can set one of the following cleanup rules:
 Delete versions older than [defined period] (available for full method only) - Select this option to limit the age of backup versions. All versions that are older than the specified period will be automatically deleted.
 Delete version chains older than [defined period] (available for incremental and differential methods only) - Select this option to limit the age of backup version chains. The oldest version chain will be deleted only when the most recent backup version of this chain is older than the specified period.
 Store no more than [n] recent versions (available for full method only) - Select this option to limit the maximum number of backup versions. When the number of versions exceeds the specified value, the oldest backup version will be automatically deleted.
 Store no more than [n] recent version chains (available for incremental and differential methods only) - Select this option to limit the maximum number of backup version chains. When the number of version chains exceeds the specified value, the oldest backup version chain will be automatically deleted.
 Keep size of the backup no more than [defined size] (not available for local backups created by Acronis True Image 2020 or later) - Select this option to limit maximum size of the backup. After creating a new backup version, the program checks whether the total backup size exceeds the specified value. If it's true, the oldest backup version will be deleted.
The first backup version option
Often the first version of any backup is one of the most valuable versions. This is true because it stores the initial data state (for example, your system partition with recently installed Windows) or some other stable data state (for example, data after a successful virus check).
Do not delete the first version of the backup - Select this check box to keep the initial data state. The program will create two initial full backup versions. The first version will be excluded from the automatic cleanup, and will be stored until you delete it manually.

61

Copyright © Acronis International GmbH, 2003-2020

If you select incremental or differential method, the first backup chain will start from the second full backup version. And only the third version of the backup will be incremental or differential one.
Note that when the check box is selected, the Store no more than [n] recent versions check box will change to Store no more than 1+[n] recent versions.
Managing custom backup schemes
If you change anything in an existing backup scheme, you can save the changed scheme as a new one. In this case you need to specify a new name for that backup scheme.  You can overwrite existing custom schemes.  You cannot overwrite existing pre-defined backup schemes.  In a scheme name, you can use any symbols allowed by OS for naming files. The maximum length
of a backup scheme name is 255 symbols.  You can create not more than 16 custom backup schemes.
After creating a custom backup scheme, you can use it as any other existing backup scheme while configuring a backup.
You can also use a custom backup scheme without saving it. In this case, it will be available only for the backup where it was created and you will be unable to use it for other backups.
If you do not need a custom backup scheme anymore, you can delete it. To delete the scheme, select it in the backup schemes list, click Delete, and then click Delete scheme in the confirmation window.
The pre-defined backup schemes cannot be deleted.
Examples of custom schemes
1. Entire PC backup "Two full versions"
Case: You want to protect all data on your computer with two full versions and you want to update the backup once a month. Let's see how you can do it by using a custom backup scheme. 1. Start configuring an entire PC backup. Refer to Backing up all data on your PC (p. 20) for details. 2. Make sure Entire PC is selected as the backup source. 3. Click Options, open the Schedule tab, click Monthly, and then specify a day of the month (for
example, the 20-th). This will result in a backup version being created on a monthly basis, on the day you specify. Then, specify a start time for the backup operation. 4. Open the Backup scheme tab, and then choose Custom scheme instead of Incremental scheme. 5. In the Backup method box, select Full from the drop-down list. 6. To limit the number of versions, click Store no more than [n] recent versions, and type or select "2", and click OK. In this case, the program will create a new full version every month, on the 20-th day. After creating the third version, the oldest version will be automatically deleted. 7. Check that all settings are correct and click Back up now. If you want your first backup to be run only at the time you specified in the Scheduler, click the down arrow to the right of the Back up now button and select Later in the drop-down list.

62

2. File backup "Daily incremental version + weekly full version"
Case: You have files and/or folders you work with every day. You need to save your daily work results and want to be able to recover data state to any date for the last three weeks. Let's see how you can do this using a custom backup scheme.
1. Start configuring a file backup. Refer to Backing up files and folders for details. 2. Click Options, open the Schedule tab, click Daily, and then specify a start time for the backup
operation. For example, if you finish your everyday work at 8 PM, specify this time or a little later (8.05 PM) as the start time. 3. Open the Backup scheme tab, and then choose Custom scheme instead of Incremental scheme. 4. In the Backup method box, select Incremental from the drop-down list. 5. Click Create a full version after every [n] incremental versions, and type or select "6".
In that case, the program will first create the initial full backup version (no matter how you set up a backup process, the first backup version will always be the full one), and then six incremental versions day by day. Then, it will create one full version and six incremental versions again and so on. So every new full version will be created in exactly a week's time. 6. To limit the storage time for the versions, click Turn on automatic cleanup. 7. Click Delete version chains older than [n] days, type or select "21", and click OK. 8. Check that all settings are correct and click Back up now. If you want your first backup to run only at the time you specified in the Scheduler, click the down arrow to the right of the Back up now button and select Later in the drop-down list.
3. Disk backup "Full version every 2 months + differential version twice a month"
Case: You need to back up your system partition twice a month and create a new full backup version every two months. In addition, you want to use no more than 100 GB of disk space to store the backup versions. Let's see how you can do it using a custom backup scheme.
1. Start configuring a disk backup. Refer to Backing up disks and partitions (p. 45). 2. Select your system partition (usually C:) as the backup source. 3. Click Options, open the Schedule tab, click Monthly, and then specify, for example, the 1st and
15th days of the month. This will result in a backup version in about every two weeks. Then, specify a start time for the backup operation. 4. Open the Backup scheme tab, and then choose Custom scheme instead of Incremental scheme. 5. In the Backup method box, select Differential from the drop-down list. 6. Click Create a full version after every [n] differential versions, and type or select "3".
In that case the program will first create the initial full backup version (no matter how you set up a backup process, the first backup version will always be the full one), and then three differential versions, each one in about two weeks. Then again a full version and three differential versions and so on. So every new full version will be created in two months. 7. To limit storage space for the versions, click Turn on automatic cleanup. 8. Click Keep size of the backup no more than [defined size], type or select "100" "GB", and click OK.
When the total backup size exceeds 100 GB, Acronis True Image 2021 will clean up the existing backup versions to make the remaining versions satisfy the size limit. The program will delete the oldest backup chain consisting of a full backup version and three differential backup versions.
9. Check that all settings are correct and click Back up now. If you want your first backup to be run only at the time you specified in the Scheduler, click the down arrow to the right of the Back up now button and select Later in the drop-down list.

4.5.3 Notifications for backup operation
Location: Options > Notifications
Sometimes a backup or recovery procedure can last an hour or longer. Acronis True Image 2021 can notify you when it is finished via email. The program can also duplicate messages issued during the operation or send you the full operation log after operation completion.
By default, all notifications are disabled.
Free disk space threshold
You may want to be notified when the free space on the backup storage becomes less than the specified threshold value. If after starting a backup Acronis True Image 2021 finds out that the free space in the selected backup location is already less than the specified value, the program will not begin the actual backup process and will immediately inform you by displaying an appropriate message. The message offers you three choices - to ignore it and proceed with the backup, to browse for another location for the backup or to cancel the backup.
If the free space becomes less than the specified value while the backup is being run, the program will display the same message and you will have to make the same decisions.
To set the free disk space threshold:  Select the Show notification message on insufficient free disk space check box  In the Size box, type or select a threshold value and select a unit of measure
Acronis True Image 2021 can monitor free space on the following storage devices:  Local hard drives  USB cards and drives  Network shares (SMB)
The message will not be displayed if the Do not show messages and dialogs while processing (silent mode) check box is selected in the Error handling settings.
This option cannot be enabled for CD/DVD drives.
Email notification
You can specify an email account that will be used to send you email notifications.
To configure the email notifications:
1. Select the Send email notifications about the operation state check box. 2. Configure email settings:
 Enter the email address in the To field. You can enter several addresses, separated by semicolons.
 Enter the outgoing mail server (SMTP) in the Outgoing mail server (SMTP) field.  Set the port of the outgoing mail server. By default, the port is set to 25.  If required, select the SMTP authentication check box, and then enter the user name and
password in the corresponding fields. 3. To check whether your settings are correct, click the Send test message button.
If the test message sending fails, perform the following:

64

Copyright © Acronis International GmbH, 2003-2020

1. Click Show extended settings. 2. Configure additional email settings:
 Enter the sender's email address in the From field. If you are not sure what address to specify, then type any address you like in a standard format, for example aaa@bbb.com.
 Change the message subject in the Subject field, if necessary. To simplify monitoring a backup status, you can add the most important information to the subject of the email messages. You can type the following text labels:  %BACKUP_NAME%--the backup name  %COMPUTER_NAME%--name of the computer where the backup was started  %OPERATION_STATUS%--result of the backup or other operation For example, you can type: Status of backup %BACKUP_NAME%: %OPERATION_STATUS% (%COMPUTER_NAME%)
 Select the Log on to incoming mail server check box.  Enter the incoming mail server (POP3) in the POP3 server field.  Set the port of the incoming mail server. By default, the port is set to 110. 3. Click the Send test message button again.
Additional notification settings:
 To send a notification concerning a process completion, select the Send notification upon operation's successful completion check box.
 To send a notification concerning a process failure, select the Send notification upon operation failure check box.
 To send a notification with operation messages, select the Send notification when user interaction is required check box.
 To send a notification with a full log of operations, select the Add full log to the notification check box.
Note that email notifications you configure work for a particular backup. If you want to receive notifications about all of your backups, you can set up email notifications in the Online Dashboard. Refer to Email notifications (p. 121) for details. Both methods work independently from each other and can be used simultaneously.
4.5.4 Excluding items from backup
Location: Options > Exclusions
If you want to exclude unnecessary files from a backup, specify the appropriate file types on the Exclusions tab of the backup options. You can specify exclusions for disk backups, file backups or online backups.
When you select a specific file for backup, it cannot be excluded by the exclusion settings. The settings are applicable only to files located on a partition, disk, or inside a folder selected for backup.

65

Copyright © Acronis International GmbH, 2003-2020

How to use the default exclusion settings
After you have installed the application, all the exclusion settings are set to the initial values. You can change them for your current backup operation only or for all backups that will be created in future. Select the Save as default check box to apply the modified settings to all further backup operations by default. If you want to reset all the modified settings to the values that they were originally set to when the product was installed, click the Reset to initial settings button.

What you can exclude and how
You have the following options to exclude files from backups:  Do not notarize digitally signed files (available for notarized backups only)--The main purpose of
a notarized backup is protection of your personal files. Therefore, there is no need to back up system files, application files, and other files that have a digital signature. To exclude these files, select the corresponding check box.  Exclude hidden files--Select this check box to exclude hidden files and folders from a file-level backup.  Exclude system files--Select this check box to exclude system files and folders from a file-level backup.
You can exclude files meeting the criteria you specify. To do this, select the Exclude files matching the following criteria check box, click the plus sign, and then enter the exclusion criterion.
We do not recommend excluding hidden and system files from the backups of your system partition.
How to add an exclusion criterion:  You can enter explicit file names for exclusion from the backup:
 file.ext - all such files will be excluded from the backup.  C:\file.ext - the file.ext file on the C: disk will be excluded.

66

Copyright © Acronis International GmbH, 2003-2020

 You can use wildcard characters (* and ?):  *.ext - all files with a .ext extension will be excluded.  ??name.ext - all files with a .ext extension, having six letters in their names (starting with any two symbols (??) and ending with name), will be excluded.
 To exclude a folder from a disk-level backup, click the plus sign, click the ellipsis button, go to the directory tree and select the folder you want to exclude, and then click OK.
To delete a criterion added by mistake, select the criterion, and then click the minus sign.

4.5.4.1 Excluding online data
Before you start a backup, you can reduce the backup size by excluding data that does not need to be backed up. Acronis True Image 2021 now allows you to exclude your local data that is uploaded or synchronized with third-party Cloud services, such as Dropbox or Microsoft OneDrive. This data is already reliably protected and can be easily downloaded to your computer. Therefore you can exclude it to reduce the backup size and to speed up the backup process.
To exclude an online data source from a backup: 1. Before you start the backup process, click Exclude items from backup. 2. Clear the check boxes next to the items that you want to exclude, and then click OK.
4.5.5 Image creation mode
Location: Options > Advanced > Image creation mode
This option is not available for the backups that use Acronis Cloud as a backup destination.
You can use these parameters to create an exact copy of your whole partitions or hard disks, and not only the sectors that contain data. For example, this can be useful when you want to back up a partition or disk containing an operating system that is not supported by Acronis True Image. Please note that this mode increases processing time and usually results in a larger image file.  To create a sector-by-sector image, select the Back up sector-by-sector check box.  To include all unallocated disk space into the backup, select the Back up unallocated space check
box. This check box is available only when the Back up sector-by-sector check box is selected.
4.5.6 Backup protection
Location: Backup dashboard > Options > Advanced > Backup protection
This topic is applicable to local and network backups. For information about protecting cloud backups, refer to Online backup protection (p. 74).
By default, there is no password protection for backups, but you can configure passwords to protect your backup files.
You cannot change the backup protection option for an existing backup.
To protect a backup: 1. Enter the password for the backup into the corresponding field. We recommend that you use a
password longer than seven symbols and containing both letters (in upper and lower cases preferably) and numbers to make it more difficult to guess.

67

Copyright © Acronis International GmbH, 2003-2020

A password cannot be retrieved. Please memorize the password that you specify for a backup protection.
2. To confirm the previously entered password, retype it into the corresponding field. 3. [optional step] To increase the security of your confidential data, you can encrypt the backup
with strong industry-standard AES (Advanced Encryption Standard) cryptographic algorithm. AES is available with three key lengths ­ 128, 192 and 256 bits to balance performance and protection as desired. The 128-bit encryption key is sufficient for most applications. The longer the key, the more secure your data. However, the 192 and 256-bit long keys significantly slow down the backup process. If you want to use AES encryption, choose one of the following keys:  AES 128 - to use 128-bit encryption key  AES 192 - to use 192-bit encryption key  AES 256 - to use 256-bit encryption key If you do not want to encrypt the backup and only want to protect a backup with a password, select None. 4. Having specified the backup settings, click OK.
How to get access to a password-protected backup
Acronis True Image asks for the password every time you try to modify the backup:  Recover data from the backup  Edit settings  Mount  Move
To access the backup, you must specify the correct password. For safety reasons, there is no wat to recover lost passwords.
4.5.7 Pre/Post commands for backup
Location: Options > Advanced > Pre/Post commands
This option is not available for the backups that use Acronis Cloud as a backup destination.
You can specify commands (or even batch files) that will be automatically executed before and after the backup procedure.
For example, you may want to start/stop certain Windows processes, or check your data before starting backup.
To specify commands (batch files):  Select the Use custom commands check box.  Select a command to be executed before the backup process starts in the Pre-command field. To
create a new command or select a new batch file, click the Edit button.  Select a command to be executed after the backup process ends in the Post-command field. To
create a new command or select a new batch file, click the Edit button.
Please do not try to execute interactive commands, i.e. commands that require user input (for example, "pause"). These are not supported.

68

Copyright © Acronis International GmbH, 2003-2020

4.5.7.1 Edit user command for backup
You can specify user commands to be executed before or after the backup procedure:  In the Command field, type-in a command or select it from the list. Click ... to select a batch file.  In the Working directory field, type-in a path for command execution or select it from the list of
previously entered paths.  In the Arguments field enter or select command execution arguments from the list. Disabling the Do not perform operations until the command's execution is complete parameter (enabled for Pre commands by default), will permit the backup process to run concurrently with your command execution.
The Abort the operation if the user command fails (enabled by default) parameter will abort the operation if any errors occur in command execution.
You can test a command you entered by clicking the Test command button.
4.5.8 Backup splitting
Location: Options > Advanced > Backup splitting
Acronis True Image 2021 cannot split already existing backups. Backups can be split only when being created.
This option is not available for the backups that use Acronis Cloud as a backup destination.
Large backups can be split into several files that together make up the original backup. A backup can also be split for burning to removable media.
The default setting - Automatic. With this setting, Acronis True Image 2021 will act as follows.
When backing up to a hard disk:  If the selected disk has enough space and its file system allows the estimated file size, the
program will create a single backup file.  If the storage disk has enough space, but its file system does not allow the estimated file size, the
program will automatically split the image into several files.  If you do not have enough space to store the image on your hard disk, the program will warn you
and wait for your decision as to how you plan to fix the problem. You can try to free some additional space and continue or select another disk.
When backing up to a CD-R/RW, DVD-R/RW, DVD+R/RW, BD-R/RE:  Acronis True Image 2021 will ask you to insert a new disk when the previous one is full. Alternatively, you may select the desired file size from the drop-down list. The backup will then be split into multiple files of the specified size. This is useful when you store a backup to a hard disk in order to burn the backup to CD-R/RW, DVD-R/RW, DVD+R/RW or BD-R/RE later on.
Creating images directly on CD-R/RW, DVD-R/RW, DVD+R/RW, BD-R/RE might take considerably more time than it would on a hard disk.

4.5.9 Backup validation option
Location: Options > Advanced > Validation This option is not available for the backups that use Acronis Cloud as a backup destination.

69

Copyright © Acronis International GmbH, 2003-2020

You can specify the following settings:
 Validate backup each time after it is completed - Select to check the integrity of the backup version immediately after backup. We recommend that you enable this option when you back up your critical data or system disk.  Validate the latest diverse backup only - A quick validation of the last backup slice.  Validate entire backup
 Validate backup on schedule - Select to schedule validation of your backups to ensure that they remain "healthy".  The latest diverse backup version when it is completed  Entire backup when it is completed
The default settings are as follows:  Frequency: once a month.  Day: the date when the backup was started.  Time: the moment of backup start plus 15 minutes.
You can also configure start of the validation manually from the backup context menu.
To do this, right-click the backup and choose:
 Validate all versions  Validate last version
Example: You start a backup operation on July 15, at 12.00. The backup version is created at 12.05. Its validation will run at 12.15 if your computer is in the "screen saver" state at the moment. If not, then the validation will not run. In a month, August 15, at 12.15, the validation will start again. As before, your computer must be in the "screen saver" state. The same will occur on September 15, and so on.
You can change the default settings and specify your own schedule. For more information see Scheduling (p. 55).

4.5.10 Backup reserve copy
Location: Options > Advanced > Backup reserve copy
This option is not available for the backups that use Acronis Cloud as a backup destination and for local backups created by Acronis True Image 2020 or later.
Backup reserve copy is an independent full backup version created immediately after a normal backup. Even when you create an incremental or differential backup version containing only data changes, the reserve copy will contain all the data selected for the normal backup. You can save reserve copies of your backups on the file system, a network drive, or a USB flash drive.
Please, be aware that CD/DVDs are not supported as locations for reserve copies.
To make a reserve copy: 1. Select the Create a reserve copy of my backups check box. 2. Specify a location for the backup copies. 3. Select the reserve copy format. You can create it as an Acronis backup (.tib files) or just copy the
source files to the selected location as is, without any modification. 4. [Optional step] Protect the reserve copy with a password.
All other backup options will be inherited from the source backup.

70

4.5.11 Removable media settings
Location: Options > Advanced > Removable media settings

When backing up to removable media, you can make this media bootable by writing additional components to it. Thus, you will not need a separate bootable disk.
Acronis True Image 2021 does not support creating bootable media if a flash drive is formatted in NTFS or exFAT. The drive must have a FAT16 or FAT32 file system.

The following settings are available:
 Place Acronis True Image 2021 on media
Acronis True Image 2021 - includes support of USB, PC Card (formerly PCMCIA), and SCSI interfaces along with the storage devices connected via them, and therefore is strongly recommended.  Place Acronis System Report on media
Acronis System Report - the component allows you to generate system report that is used for collecting information about your system in case of any program problem. Report generation will be available before you start Acronis True Image 2021 from the bootable media. The generated system report can be saved to a USB flash drive.  Ask for first media while creating backups on removable media
You can choose whether to display the Insert First Media prompt when backing up to removable media. With the default setting, backing up to removable media may not be possible if the user is away, because the program will wait for someone to press OK in the prompt box. Therefore, you should disable the prompt when scheduling a backup to removable media. Then, if the removable media is available (for example, CD-R/RW inserted) the backup can run unattended.
If you have other Acronis products installed on your computer, the bootable versions of these programs' components will be offered as well.

32-bit or 64-bit components

4.5.12 Error handling
When Acronis True Image 2021 encounters an error while performing a backup, it stops the backup process and displays a message, waiting for a response on how to handle the error. You can configure an error handling policy, so Acronis True Image 2021 will not stop the backup process, but will handle the error according to the rules that you set, and will continue working.

71

Copyright © Acronis International GmbH, 2003-2020

Note This topic applies to backups that use local or network backup destinations. For error handing options for backups that use Acronis Cloud as a backup destination, see Error handling for Cloud backups and replicas (p. 72).
To set up the error handling policy: 1. On the Backup dashboard > Options > Advanced > Error handling 2. Set the error handling policy:
 Do not show messages and dialogs while processing (silent mode) - Enable this setting to ignore errors during backup operations. This is useful when you cannot control the backup process.
 Ignore bad sectors - This option is available only for disk and partition backups. It lets you successfully complete a backup even if there are bad sectors on the hard disk. We recommend that you select this check box when your hard drive is failing, for example:  Hard drive is making clicking or grinding noises during operation.  The S.M.A.R.T. system has detected hard drive issues and recommends that you back up the drive as soon as possible. When you leave this check box cleared, the backup may fail because of possible bad sectors on the drive.
 When not enough space in ASZ, delete the oldest backup (enabled by default) - We recommend that you select this check box when planning unattended scheduled backups to the Acronis Secure Zone. Otherwise, when the Acronis Secure Zone is full during a backup operation, Acronis True Image suspends the backup and requires your action. The dialog will open even when the Do not show messages and dialogs while processing (silent mode) setting is enabled.
 Repeat attempt if a backup fails - This option allows you to automatically repeat a backup attempt if the backup fails for some reason. You can specify the number of attempts and the interval between attempts. Note that if the error interrupting the backup persists, the backup will not be created.
Note: Scheduled backup operations will not start until all attempts are completed.
3. Click OK.
4.5.12.1 Error handling for Cloud backups and replicas
You can configure Acronis True Image 2021 to retry failed backups and replications to Cloud.
To configure the number of retry attempts and the interval between them: 1. On the Backup dashboard, click a backup to Cloud, click Options, and go to the Advanced tab. 2. Under Error handling, select the Repeat backup attempts check box, and then choose the
number of attempts (from 1 to 99) and the interval between them. 3. Click OK.
The new setting will be applied for all following backup and replication operations to Cloud for the selected backup object.
Note: Scheduled backup operations will not start until all attempts to repeat the backup are completed.
4.5.13 File-level security settings for backup
Location: Options > Advanced > File-level security settings

72

Copyright © Acronis International GmbH, 2003-2020

This option is only available for file-level backups.
This option is not available for the backups that use Acronis Cloud as a backup destination.
You can specify security settings for backed up files:
 Preserve file security settings in backups - selecting this option will preserve all the security properties (permissions assigned to groups or users) of the backup files for further recovery. By default, files and folders are saved in the backup with their original Windows security settings (i.e. permissions for read, write, execute and so on for each user or user group, set in file Properties -> Security). If you recover a secured file/folder on a computer without the user specified in the permissions, you may not be able to read or modify this file. To eliminate this kind of problem, you can disable preserving file security settings in backups. Then the recovered files/folders will always inherit the permissions from the folder to which they are recovered (parent folder or disk, if recovered to the root). Or, you can disable file security settings during recovery, even if they are available in the backup. The result will be the same.
 In backups, store encrypted files in a decrypted state (the preset is disabled) - check the option if there are encrypted files in the backup and you want them to be accessed by any user after recovery. Otherwise, only the user who encrypted the files/folders will be able to read them. Decryption may also be useful if you are going to recover encrypted files on another computer. If you do not use the encryption feature available in Windows XP and later operating systems, simply ignore this option. (Files/folders encryption is set in Properties -> General -> Advanced Attributes -> Encrypt contents to secure data).

4.5.14 Computer shutdown
Location: Options > Advanced > Computer shutdown
You can configure the following options:
 Stop all current operations when I shut down the computer When you turn off your computer while Acronis True Image 2021 is performing a long operation, for example a disk backup to the cloud, this operation prevents the computer from shutdown. When this check box is selected, Acronis True Image 2021 automatically stops all its current operations before shutdown. This may take about two minutes. The next time you run Acronis True Image 2021, it will restart the stopped backups.
 Shut down the computer after the backup is complete If you know that the backup process you are configuring may take a long time, you may select the Shut down the computer after the backup is complete check box. In this case, you will not have to wait until the operation completion. The program will perform the backup and turn off your computer automatically.
This option is also useful when you schedule your backups. For example, you may want to perform backups every weekday in the evening to save all your work. Schedule the backup and select the check box. After that you may leave your computer when you finish your work knowing that the critical data will be backed up and the computer will be turned off.

4.5.15 Acronis Cloud cleanup
Location: Options > Advanced > Acronis Cloud cleanup

73

Copyright © Acronis International GmbH, 2003-2020

This option is only available for online backup.
You can configure the cleanup settings for Acronis Cloud to optimize usage of its space.
To set the limits for the amount of versions on Acronis Cloud:  Select the Delete backup versions that are older than check box and enter a value that limits the
maximum age of the older versions. All other versions will be automatically deleted except the most recent versions.  Use the Store no more than ... recent backup versions option to enter a value that limits the maximum number of all versions in the storage.

4.5.16 Online backup protection
Location: Options > Advanced > Backup protection
To protect your data on Acronis Cloud from unauthorized access, you can use encryption. In this case, when you back up your data, it will be encrypted by using the AES-256 algorithm and then saved to Acronis Cloud. To encrypt and decrypt your data, the program needs the password, that you should specify when you configure the online backup. You can specify any set of characters you like. Note that the password is case-sensitive.
Warning! A password of an online backup cannot be retrieved. Please memorize the password that you specify for backup protection.
While attempting to access the encrypted data, the program asks you to enter the password.
Note that you cannot set or change the password for a pre-existing online backup.

4.5.17 Performance of backup operation
Location: Options > Advanced > Performance

74

Compression level
You can choose the compression level for a backup:
 None - the data will be copied without any compression, which may significantly increase the backup file size.
 Normal - the recommended data compression level (set by default).  High - higher backup file compression level, takes more time to create a backup.  Maximum - maximum backup compression, but takes a long time to create a backup.
The optimal data compression level depends on the type of files stored in the backup. For example, even maximum compression will not significantly reduce the backup size, if the backup contains essentially compressed files, like .jpg, .pdf or .mp3.
You cannot set or change the compression level for a pre-existing backup.

Operation priority
Changing the priority of a backup or recovery process can make it run faster or slower (depending on whether you raise or lower the priority), but it can also adversely affect the performance of other running programs. The priority of any process running in a system, determines the amount of CPU usage and system resources allocated to that process. Decreasing the operation priority will free more resources for other CPU tasks. Increasing backup or recovery priority may speed up the process by taking resources from the other currently running processes. The effect will depend on total CPU usage and other factors.
You can set up the operation priority:  Low (enabled by default) - the backup or recovery process will run slower, but the performance
of other programs will be increased.  Normal - the backup or recovery process will have the equal priority with other processes.  High - the backup or recovery process will run faster, but the performance of other programs will
be reduced. Be aware that selecting this option may result in 100% CPU usage by Acronis True Image 2021.
Network connection transfer rate
When you back up data to Acronis Cloud, you can change the connection speed used by Acronis True Image 2021. Set the connection speed that will allow you to use Internet and network resources without annoying slowdowns.
To set up the connection speed, select one of the following options:  Maximum
The data transfer rate is maximum within a system configuration.  Limit to
You can specify a maximum value for data upload speed.
Snapshot for backup
This option is for advanced users only. Do not change the default setting if you are not sure which option to choose.
During a disk or partition backup process, which often takes a long time, some of the backed-up files may be in use, locked, or being modified in one way or another. For example, you may work on a document and save it from time to time. If Acronis True Image 2021 backed up files one by one, your open file would likely be changed since the backup start, and then saved in the backup to a different

75

Copyright © Acronis International GmbH, 2003-2020

point in time. Therefore, the data in the backup would be inconsistent. To eliminate it, Acronis True Image 2021 creates a so-called snapshot that fixes the data to back up to a particular point in time. This is done before the backup starts and guarantees that the data is in consistent state.
Select a backup snapshot type from the list:  No snapshot
A snapshot will not be created. The files will be backed up one by one as an ordinary copy operation.  VSS
Warning! This is the only recommended option for backing up your system. Your computer may not start after recovery from a backup created with a different snapshot type.
This option is default for disk-level and the Entire PC backups, and guarantees data consistency in the backup.  Acronis snapshot A snapshot will be created with the Acronis driver used in previous versions of Acronis True Image.  VSS without writers This option is default for file-level backups. VSS writers are special VSS components for notifying applications that a snapshot is going to be created, so that the applications prepare their data for the snapshot. The writers are needed for applications that perform large number of file operations and require data consistency, for example databases. Because such applications are not installed on home computers, there is no need to use writers. In addition, this reduces the time required for file-level backups.
4.5.18 Selecting a data center for backup
Location: Options > Advanced > Data center
This option is only available for online backup.
When you create a backup to Acronis Cloud, your data is uploaded to one of the Acronis data centers located in different countries. Initially, the data center is defined as the one closest to your location when you create your Acronis account. Afterwards, your online backups and synced files are stored in the same data center, by default.
We recommend that you set the data center for a backup manually, when you are in a different country and your default data center is not the closest to your current location. This will significantly increase the data upload rate.
Note: You cannot change the data center for a pre-existing backup.
To select a data center:
1. On the Online Backup Options screen, click Advanced, and then click Data center. 2. Select the country that is closest to your current location.
4.5.19 Laptop power settings
Location: Settings > Battery power saving
This setting is only available on computers with batteries (laptops, computers with UPS).

76

Copyright © Acronis International GmbH, 2003-2020

When you work on your laptop and there is no power supply around you or when your computer has switched to UPS after a blackout, it's reasonable to save the battery charge. Long-term backups may consume the battery power quite fast, for example when you back up significant amount of data to the cloud.
To save the battery charge:  On the sidebar, click Settings > Battery power saving, select the Do not back up when battery
power is less than check box, and then use the slider to set the exact battery level for the charge saving to start.
When this setting is turned on, if you unplug your laptop power adapter or use a UPS for your computer after a blackout, and the remaining battery charge is equal or below the level in the slider, all current backups are paused and scheduled backups will not start. Once you plug the power adapter back in or the power supply is restored, the paused backups will be resumed. The scheduled backups that have been missed because of this setting will be started as well.
This setting does not block backup functionality completely. You can always start a backup manually.
Local mobile backups do not depend on this setting. Your mobile data is backed up to local storage on your computer as usual.
4.5.20 Wi-Fi networks for backup to Acronis Cloud
Location: Settings > Wi-Fi networks for backup
When you back up your data to Acronis Cloud, you can be concerned about the security of your personal data when it is transferred by unprotected Wi-Fi networks. To avoid the risk of theft of your personal data, we strongly recommend that you only use protected Wi-Fi networks.
To protect your data:  On the sidebar, click Settings > Wi-Fi networks for backup, and then click Set networks. In the
Wi-Fi networks for backup window which contains all currently available and saved unavailable Wi-Fi networks, select the check boxes next to the networks that you want to use to back up your data.
When the networks are selected and your computer loses a connection to any of them, all current backups are paused and scheduled backups will not start. Once the computer connects to any of these networks, the suspended backups will be resumed. The scheduled backups that have been missed because of this setting will be started as well.
To back up your data by using a new Wi-Fi network, simply select it in the Wi-Fi networks for backup window. This can be done whenever you need to use new network.
Local mobile backups do not depend on this setting. Your mobile data is backed up to local storage on your computer, as usual.

4.6 Operations with backups
4.6.1 Backup operations menu
The backup operations menu provides quick access to additional operations that can be performed with the selected backup.

The backup operations menu can contain the following items:
 Rename - allows you to set a new name for a backup in the list. The backup files will not be renamed.
 Reconfigure (for backups manually added to the backup list) - allows configuring the settings of a backup created by a previous Acronis True Image version. This item may also appear for backups created on another computer and added to the backup list without importing their settings.
Without backup settings, you cannot refresh the backup by clicking Back up now. Also, you cannot edit and clone the backup settings.  Reconfigure (for online backups) - allows you to bind a selected online backup to the current computer. To do this, click this item and reconfigure settings of the backup. Note that only one online backup can be active on one computer.  Validate all versions - starts validation of all backup slices.  Validate last version - starts quick validation of the last backup slice.  Clean up versions - allows you to delete backup versions you no longer need.  Clone settings - creates a new empty backup box with the settings of the initial backup and named (1) [the initial backup name]. Change the settings, save them, and then click Back up now on the cloned backup box.  Move - click to move all of the backup files to another location. The subsequent backup versions will be saved to the new location.
If you change the backup destination by editing the backup settings, only new backup versions will be saved to the new location. The earlier backup versions will remain in the old location.  Delete - depending on a backup type, this command completely deletes the backup from its location, or allows you to choose whether you want to delete the backup completely or the

78

Copyright © Acronis International GmbH, 2003-2020

backup box only. When you delete a backup box, the backup files remain in the location and you will be able to add the backup to the list later. Note that when you delete a backup completely, the deletion cannot be undone.  Open location - opens the folder containing the backup files.  Search files - allows you to find a specific file or folder in a backup by entering its name into the search field.  Convert to VHD (for disk-level backups) - allows you to convert a selected Acronis backup version (.tibx file) to virtual hard disks (.vhd(x) files). The initial backup version will not be modified.
4.6.2 Backup activity and statistics
On the Activity tab and the Backup tab, you can view additional information on a backup, such as backup history and file types the backup contains. The Activity tab contains a list of operations performed on the selected backup starting from its creation, the operation statuses, and statistics. This comes in handy when you need to find out what was happening to the backup in background mode, for example the number and statuses of scheduled backup operations, size of backed-up data, results of backup validation, etc.
When you create the first version of a backup, the Backup tab displays a graphical representation of the backup content by file types.
The Activity tab
Nonstop backup and mobile backups do not have an activity feed.
To view a backup activity:
1. On the sidebar, click Backup. 2. In the backup list, select the backup, the history of which you want to view. 3. On the right pane, click Activity.

What you can view and analyze:
 Backup operations and their statuses (successful, failed, canceled, interrupted, and so on)  Operations performed on the backup, and their statuses  Error messages  Backup comments  Backup operation details, including:
 Backed up--Size of the data that the last backup version contains. For file-level backups, Acronis True Image 2021 calculates the size of files to back up. The value of this parameter is equal to the value of the Data to recover for full backup versions. For differential and incremental versions, it is usually less than the Data to recover, because in this case Acronis True Image 2021 additionally uses data from the previous versions for recovery.
For disk-level backups, Acronis True Image 2021 calculates the size of the hard drive sectors that contain data to back up. Because sectors may contain hard links to the files, even for full

79

Copyright © Acronis International GmbH, 2003-2020

disk-level backup versions the value of this parameter can be less than the value of the Data to recover parameter.  Speed--Backup operation speed.  Time spent--Time spent for the backup operation.  Data to recover--Size of the data that can be recovered from the last backup version.  Method--Backup operation method (full, incremental, or differential).
For more information, refer to the Knowledge Base article: https://kb.acronis.com/content/60104.
The Backup tab
When a backup is created, you can view statistics on types of the backed-up files that the last backup version contains:

Point to a color segment to see the number of files and the total size for each data category:
 Pictures  Video files  Audio files  Documents  System files  Other file types, including hidden system files
Information on the data size:
 Data to recover--size of the original data that you selected to back up.

4.6.3 Sorting backups in the list
By default, the backups are sorted by the date they were created, starting from the newest to oldest. To change the order, select the appropriate sorting type in the upper part of the backup list. You have the following options:

Command

Description

Name

This command sorts all backups in alphabetical order. To reverse the order, select Z --> A.

Date created

This command sorts all backups from newest to oldest.

To reverse the order, select Oldest on top.

80

Command Sort by Date updated
Size Source type Destination type

Description
This command sorts all backups by date of the last version. The newer the last backup version, the higher the backup will be placed in the list.
To reverse the order, select Least recent on top.
This command sorts all backups by size, from biggest to smallest.
To reverse the order, select Smallest on top.
This command sorts all backups by the source type. The order is as follows: entire PC backups - disk backups - file backups - nonstop backup.
This command sorts all backups by the destination type. The order is as follows: internal disk drives - external disk drives - NAS devices - network shares - Acronis Cloud.

4.6.4 Replicating backups to Acronis Cloud
Why replicate?
Even though backing up your data provides protection, we recommend that you also replicate all local backups to Acronis Cloud, to protect from incidental corruption of your computer. Of course, you can create two backup plans, one to back up to your local computer and another one to Acronis Cloud. But automatic replication saves time when setting up the backup plans and creating a replica is faster than creating another backup. A replica is a copy of your backup and it can be used as a safeguard and accessed from anywhere.
Replication activation
Replication is not activated by default. You can activate it for any local backup of a disk, partition or entire computer that uses the local destination (to an external or internal disk) that you configured in Acronis True Image 2020 or higher. You can activate the replication in a special tab of a backup plan.
To activate the replication of a backup to Acronis Cloud: 1. From the backup list, select the backup that you want to replicate, and then open the Replica
tab. 2. Click Replicate. Now, replication is activated and will start once the normal backup is created.
You are free to close Acronis True Image. Both the backup and replication processes will continue in background mode. 3. [optional step] Click Options > Advanced > Replication to Acronis Cloud to see the data center where your backup replication is stored and to configure the cleanup settings (p. 83) for Acronis Cloud to optimize usage of its space.
Protection of replicated data
Replicated data is uploaded to Acronis Cloud by using Secure Socket Layer (SSL).
In the Cloud, data is stored according to your encryption settings. If no encryption password is set, the replicated data is stored unecrypted. Otherwise, data is encrypted by using AES-256.

81

Copyright © Acronis International GmbH, 2003-2020

4.6.5 Validating backups
The validation procedure checks whether you will be able to recover data from a backup.
For example, backup validation is important before you recover your system. If you start recovery from a corrupted backup, the process will fail and your computer may become unbootable. We recommend that you validate system partition backups under bootable media. Other backups may be validated in Windows. See also Preparing for recovery (p. 88) and Basic concepts (p. 30).
Validating backups in Windows
To validate an entire backup:
1. Start Acronis True Image 2021, and then click Backup on the sidebar. 2. In the backup list, click the down arrow icon next to the backup to validate, and then click
Validate.
Validating backups in a standalone version of Acronis True Image (bootable media)
To validate a specific backup version or an entire backup:
1. On the Recovery tab, find the backup that contains the version that you want to validate. If the backup is not listed, click Browse for backup, and then specify the path to the backup. Acronis True Image adds this backup to the list.
2. Right-click the backup or a specific version, and then click Validate Archive. This opens the Validate Wizard.
3. Click Proceed.
4.6.6 Backup to various places
You can save versions of a backup to different destinations by changing the backup destination when editing the backup settings. For example, after you save the initial full backup to an external USB hard drive, you can change the backup destination to a USB stick by editing the backup settings. The subsequent incremental or differential backups will be written to the USB stick.
You cannot continue backing up to an optical disc.
Acronis Secure Zone and FTP servers can contain an entire backup only.
Splitting backups on-the-fly
When free space on the destination storage (CD-R/RW or DVD-R/RW) is insufficient to complete the current backup operation, the program displays a warning message.
To complete the backup, perform one of the following:  Free up some space on the disk, and then click Retry.  Click Browse, and then select another storage device.  Click Format to erase all data on the disk, and then proceed with the backup. When versions of a backup are stored in different locations, you may need to specify the locations during recovery.

82

Copyright © Acronis International GmbH, 2003-2020

4.6.7 Adding an existing backup to the list
You may have Acronis True Image backups created by a previous product version or copied from another computer. Every time you start Acronis True Image 2021, it scans your computer for such backups and adds them to the backup list automatically.
If you have backups that are not shown in the list, you can add them manually.
To add backups manually: 1. In the Backup section, at the bottom of the backup list, click the arrow icon, and then click Add
existing backup. The program opens a window where you can browse for backups on your computer. 2. Select a backup version (a .tib file), and then click Add. The entire backup will be added to the list.
4.6.8 Cleaning up backups, backup versions, and replicas
To delete backups and backup versions that you no longer need, use the tools provided by Acronis True Image 2021.
Acronis True Image 2021 stores information on the backups in a metadata information database. Therefore, deleting unneeded backup files in File Explorer will not delete the information about these backups from the database. This will result in errors when the program tries to perform operations on the backups that no longer exist.
Deleting an entire backup and its replica
To delete an entire backup and its replica:
In the Backup section, click the down arrow icon next to the backup to delete, and then click Delete.
Depending on the backup type, this command completely deletes the backup from its location, or allows you to choose whether you want to delete the backup completely or delete the backup box only. When you delete a backup box only, the backup files remain in the location and you will be able to add the backup to the list later. Note that if you delete a backup completely, the deletion cannot be undone.
When you delete a backup, its replica is deleted automatically together with it. You cannot delete a local backup and still save its replica. However, you can delete a replica alone and keep the local backup.
Deleting an entire backup replica
You can delete a replica with its original backup or separately. To delete it with the backup, delete the backup in the way described above.
To delete a replica without deleting the backup:
In the Backup section, click the down arrow icon next to the backup with the replica to delete, and then click Delete replica.
Cleaning up backup versions manually
Use this method when you need to delete specific backup versions. In the Backup section, locate the backup that you want to clean up, click the down arrow icon next to it, click Clean up versions, and

83

Copyright © Acronis International GmbH, 2003-2020

then follow the on-screen instructions. Refer to Cleaning up backup versions manually (p. 84) for details.
After the cleanup, some auxiliary files may stay in the storage. Please do not delete them!
Cleaning up backup versions automatically
To configure automatic cleanup rules for a backup:
1. Go to the Backup section. 2. Perform one of the following:
 For a new backup, click Add backup, choose Create new backup, select backup source and destination, and then click Options.
 For an existing backup, select the backup from the backup list, and then click Options. 3. On the Backup scheme tab, select Custom scheme, select a backup method, and then click Turn
on automatic cleanup. 4. Configure cleanup rules for the backup.
Refer to Custom schemes (p. 60) for details.
After the cleanup, some auxiliary files may stay in the storage. Please do not delete them!
Cleaning up replica versions manually
For local backups that are replicated to Acronis Cloud, you can clean up specific replica versions manually. In the Backup section, locate the backup which replica versions you want to clean up, click the down arrow icon and select Clean up versions. Under Delete versions from, select Acronis Cloud. Refer to Cleaning up backup versions manually (p. 84) for details.
Cleaning up replica versions automatically
To configure automatic cleanup rules for a backup replica:
1. Go to the Backup section. 2. From the backup list, select the backup for which you want to clean up replica versions, and then
click Options. 3. On the Advanced tab, open the Replication to Acronis Cloud tab.
 Use the Store no more than ... recent backup versions option to enter a value that limits the maximum number of replica versions that are stored.
 Select the Delete backup versions that are older than check box and enter a value that limits the maximum age of the older versions. The most recent versions will be kept and all other versions will be automatically deleted.
4.6.8.1 Cleaning up backup and replica versions manually
When you want to delete backup versions that you no longer need, use the tools provided in the application. If you delete backup version files outside Acronis True Image 2021, for example in File Explorer, this will result in errors during operations with the backups.
For information about other ways to delete backups and backup versions, refer to Cleaning up backups and backup versions (p. 83).
Versions of the following backups cannot be deleted manually:  Backups stored on CD, DVD, BD, or Acronis Secure Zone.

84

Copyright © Acronis International GmbH, 2003-2020

 Nonstop backups.  Notarized backups.
To clean up specific backup versions:
1. Start Acronis True Image 2021. 2. In the Backup section, click the down arrow icon next to the backup to clean up, and then click
Clean up versions. The Clean up backup versions window opens. 3. Select the location from which you want to clean up versions.  Local folder  Acronis Cloud 4. By default, Acronis True Image 2021 selects to delete all backup versions except the last one. If the last version is an incremental or differential one, then the last backup chain will not be selected. If you want to delete:  All versions except the last one, then click Delete.  Specific versions, then clear the check boxes next to the versions that you want to keep, and
then click Delete.
Please wait for the cleanup operation to complete. After the cleanup, some auxiliary files may stay in the storage. Please do not delete them.
Cleaning up versions that have dependent versions
When you select a backup version to delete, please remember that this version may have dependent versions. In this case, the dependent versions will be selected for deletion as well, because data recovery from such versions becomes impossible.  When you select a full version - the program also selects all dependent incremental and
differential versions till the next full version. In other words, the entire backup version chain will be deleted.  When you select a differential version - the program also selects all dependent incremental versions within the backup version chain.  When you select an incremental version - the program also selects all dependent incremental versions within the backup version chain.
To clean up specific replica versions:
1. Start Acronis True Image 2021. 2. In the Backup section, locate a local backup that is replicated to cloud, click the down arrow and
select Clean up versions. The Clean up backup versions dialog opens. 3. Under Delete versions from, select Acronis Cloud. The list of backup replica versions appears. 4. Select the replicas that you want to delete and click Delete. 5. In the confirmation dialog, click Delete.

5.1 Recovering disks and partitions
5.1.1 Recovering your system after a crash
When your computer fails to boot, it is advisable to at first try to find the cause using the suggestions given in Trying to determine the crash cause (p. 88). If the crash is caused by corruption of the operating system, use a backup to recover your system. Make the preparations described in Preparing for recovery (p. 88) and then proceed with recovering your system.
5.1.1.1 Trying to determine the crash cause
A system crash can be due to two basic factors:  Hardware failure
In this scenario, it is better to let your service center handle the repairs. However, you may want to perform some routine tests. Check the cables, connectors, power of external devices, etc. Then, restart the computer. If there is a hardware problem, the Power-On Self Test (POST) will inform you about the failure. If the POST does not reveal a hardware failure, enter BIOS and check whether it recognizes your system hard disk drive. To enter BIOS, press the required key combination (Del, F1, Ctrl+Alt+Esc, Ctrl+Esc, or some other, depending on your BIOS) during the POST sequence. Usually the message with the required key combination is displayed during the startup test. Pressing this combination takes you to the setup menu. Go to the hard disk autodetection utility which usually comes under "Standard CMOS Setup" or "Advanced CMOS setup". If the utility does not detect the system drive, it has failed and you need to replace the drive.  Operating system corruption (Windows cannot start up) If the POST correctly detects your system hard disk drive, then the cause of the crash is probably a virus, malware or corruption of a system file required for booting. In this case, recover the system using a backup of your system disk or system partition. Refer to Recovering your system (p. 89) for details.
5.1.1.2 Preparing for recovery
We recommend that you perform the following actions before recovery:  Scan the computer for viruses if you suspect that the crash occurred due to a virus or malware
attack.  Under bootable media, try a test recovery to a spare hard drive, if you have one.

88

Copyright © Acronis International GmbH, 2003-2020

 Validate the image under bootable media. A backup that can be read during validation in Windows, may not always be readable in a Linux environment.
Under bootable media, there are two ways to validate a backup:  To validate a backup manually, on the Recovery tab, right-click a backup and select Validate
Archive.  To validate a backup automatically before recovery, on the Options step of the Recovery
Wizard, select the Validate backup archive before recovery check box.

 Assign unique names (labels) to all partitions on your hard drives. This will make finding the disk containing your backups easier. When you use the Acronis bootable media, it creates disk drive letters that might differ from the way Windows identifies drives. For example, the D: disk identified in the standalone Acronis True Image might correspond to the E: disk in Windows.
5.1.1.3 Recovering your system to the same disk
Before you start, we recommend that you complete the procedures described in Preparing for recovery (p. 88).
To recover your system:
1. Attach the external drive if it contains the backup to be used for recovery and make sure that the drive is powered on.
2. Arrange the boot order in BIOS so as to make your rescue media device (CD, DVD or USB drive) the first boot device. See Arranging boot order in BIOS or UEFI BIOS (p. 100). If you use an UEFI computer, please pay attention to the boot mode of the bootable media in UEFI BIOS. It is recommended that the boot mode matches the type of the system in the backup. If the backup contains a BIOS system, then boot the bootable media in BIOS mode; if the system is UEFI, then ensure that UEFI mode is set.
3. Boot from the rescue media and select Acronis True Image 2021.

89

4. On the Home screen, select My disks below Recover.
5. Select the system disk or partition backup to be used for recovery. When the backup is not displayed, click Browse and specify path to the backup manually.
If the backup is located on a USB drive, and the drive is not recognized correctly, check the USB port version. If it is a USB 3.0 or USB 3.1, try connecting the drive to a USB 2.0 port.
6. Select Recover whole disks and partitions at the Recovery method step.

90

Copyright © Acronis International GmbH, 2003-2020

7. Select the system partition (usually C) on the What to recover screen. If the system partition has a different letter, select the partition using the Flags column. It must have the Pri, Act flags. If you have the System Reserved partition, select it, too.
8. At the "Settings of partition C" (or the letter of the system partition, if it is different) step check the default settings and click Next if they are correct. Otherwise, change the settings as required before clicking Next. Changing the settings will be needed when recovering to the new hard disk of a different capacity.

91

Copyright © Acronis International GmbH, 2003-2020

9. Carefully read the summary of operations at the Finish step. If you have not resized the partition, the sizes in the Deleting partition and Recovering partition items must match. Having checked the summary click Proceed.

10. When the operation finishes, exit the standalone version of Acronis True Image 2021, remove the rescue media and boot from the recovered system partition. After making sure that you have recovered Windows to the state you need, restore the original boot order.

5.1.1.4 Recovering your system to a new disk under bootable media
Before you start, we recommend that you complete the preparations described in Preparing for recovery (p. 88). You do not need to format the new disk, as this will be done in the process of recovery.
Note: It is recommended that your old and new hard drives work in the same controller mode (for example, IDE or AHCI). Otherwise, your computer might not start from the new hard drive.
To recover your system to a new disk:
1. Install the new hard drive to the same position in the computer and use the same cable and connector that was used for the original drive. If this is not possible, install the new drive to where it will be used.
2. Attach the external drive if it contains the backup to be used for recovery and make sure that the drive is powered on.
3. Arrange the boot order in BIOS so as to make your bootable media (CD, DVD or USB stick) the first boot device. See Arranging boot order in BIOS or UEFI BIOS (p. 100). If you use an UEFI computer, please pay attention to the boot mode of the bootable media in UEFI BIOS. It is recommended that the boot mode matches the type of the system in the backup. If the backup contains a BIOS system, then boot the bootable media in BIOS mode; if the system is UEFI, then ensure that UEFI mode is set.
4. Boot from the bootable media and select Acronis True Image 2021. 5. On the Home screen, select My disks below Recover.

92

Copyright © Acronis International GmbH, 2003-2020

6. Select the system disk or partition backup to be used for recovery. When the backup is not displayed, click Browse and specify path to the backup manually.
If the backup is located on a USB drive, and the drive is not recognized correctly, check the USB port version. If it is a USB 3.0 or USB 3.1, try connecting the drive to a USB 2.0 port.
7. If you have a hidden partition (for example, the System Reserved partition or a partition created by the PC manufacturer), click Details on the wizard's toolbar. Please remember the location and size of the hidden partition, because these parameters need to be the same on your new disk.
8. Select Recover whole disks and partitions at the Recovery method step. 9. On the What to recover step, select the boxes of the partitions to be recovered.
If you select an entire disk, MBR and Track 0 of the disk will also be recovered.

Selecting partitions leads to appearance of the relevant steps "Settings of partition ...". Note that these steps start with partitions which do not have an assigned disk letter (as usually is the case

93

Copyright © Acronis International GmbH, 2003-2020

with hidden partitions). The partitions then take an ascending order of partition disk letters. This order cannot be changed. The order may differ from the physical order of the partitions on the hard disk. 10. On the Settings of the hidden partition step (usually named Settings of Partition 1-1), specify the following settings:  Location. Click New location, select your new disk by either its assigned name or capacity,
and then click Accept.
 Type. Check the partition type and change it, if necessary. Ensure that the System Reserved partition (if any) is primary and marked as active.

94

Copyright © Acronis International GmbH, 2003-2020

 Size. Click Change default in the Partition size area. By default the partition occupies the entire new disk. Enter the correct size in the Partition size field (you can see this value on the What to recover step). Then drag this partition to the same location that you saw in the Backup Information window, if necessary. Click Accept.

11. On the Settings of Partition C step, specify the settings for the second partition, which in this case is your system partition.  Click New location, and then select unallocated space on the destination disk that will receive the partition.

 Change the partition type, if necessary. The system partition must be primary.

95

Copyright © Acronis International GmbH, 2003-2020

 Specify the partition size, which by default equals the original size. Usually there is no free space after the partition, so allocate all the unallocated space on the new disk to the second partition. Click Accept, and then click Next.

12. Carefully read the summary of operations to be performed and then click Proceed.
When the recovery is complete
Before you boot the computer, please disconnect the old drive (if any). If Windows "sees" both the new and old drive during the boot, this will result in problems booting Windows. If you upgrade the old drive to a larger capacity new one, disconnect the old drive before the first boot.
Remove the bootable media and boot the computer to Windows. It may report that new hardware (hard drive) is found and Windows needs to reboot. After making sure that the system operates normally, restore the original boot order.
Acronis Universal Restore
When you recover your system to dissimilar hardware, the target computer could fail to boot. This is because the new hardware is incompatible with critical drivers included in the image. Acronis Universal Restore will help you make the target computer bootable. Refer to Acronis Universal Restore (p. 185) for details.
5.1.2 Recovering partitions and disks
You can recover your disks from backups located on local storage, network storage, or Acronis Cloud.
Depending on your Internet connection speed, disk recovery from Acronis Cloud may take a long time.
To recover partitions or disks: 1. Start Acronis True Image 2021. 2. If you want to recover your data from Acronis Cloud, make sure that you are signed in to your
Acronis account.

96

5.1.2.1 Partition properties
When you recover partitions to a basic disk, you can change properties of these partitions. To open the Partition Properties window, click Properties next to the selected target partition.

You can change the following partition properties:
 Letter  Label  Type
You can make the partition primary, primary active, or logical.  Size
You can resize the partition by dragging the right-side border with your mouse, on the horizontal bar on the screen. To assign the partition a specific size, enter the appropriate number into the Partition size field. You can also select the position of unallocated space--before or after the partition.

5.1.3 About recovery of dynamic/GPT disks and volumes
Recovery of dynamic volumes
You can recover dynamic volumes to the following locations on the local hard drives:  Dynamic volume.
Manual resizing of dynamic volumes during recovery to dynamic disks is not supported. If you need to resize a dynamic volume during recovery, it should be recovered to a basic disk.
 Original location (to the same dynamic volume). The target volume type does not change.
 Another dynamic disk or volume. The target volume type does not change. For example, when recovering a dynamic striped volume over a dynamic spanned volume the target volume remains spanned.
 Unallocated space of the dynamic group. The recovered volume type will be the same as it was in the backup.

98

Copyright © Acronis International GmbH, 2003-2020

 Basic volume or disk.
The target volume remains basic.  Bare-metal recovery.
When performing a so called "bare-metal recovery" of dynamic volumes to a new unformatted disk, the recovered volumes become basic. If you want the recovered volumes to remain dynamic, the target disks should be prepared as dynamic (partitioned and formatted). This can be done using third-party tools, for example, Windows Disk Management snap-in.

Recovery of basic volumes and disks  When recovering a basic volume to an unallocated space of the dynamic group, the recovered
volume becomes dynamic.  When recovering a basic disk to a dynamic disk of a dynamic group consisting of two disks, the
recovered disk remains basic. The dynamic disk to which the recovery is performed becomes "missing" and a spanned/striped dynamic volume on the second disk becomes "failed".

Partition style after recovery

The target disk's partition style depends on whether your computer supports UEFI and on whether your system is BIOS-booted or UEFI-booted. See the following table:

My system is BIOS-booted (Windows or My system is UEFI-booted (Windows or

Example of recovery procedure
See Example of recovery to a UEFI system (p. 99).

5.1.3.1 Example of recovery to a UEFI system
Here is an example for transferring a system with the following conditions:
 The source disk is MBR and the OS supports UEFI.  The target system is UEFI-booted.  Your old and new hard drives work in the same controller mode (for example, IDE or AHCI).

99

Copyright © Acronis International GmbH, 2003-2020

Before you start the procedure, please ensure that you have:
 Acronis bootable media. Refer to Creating Acronis bootable media (p. 19) for details.
 Backup of your system disk created in disk mode. To create this backup, switch to disk mode, and then select the hard drive that contains your system partition. Refer to Backing up disks and partitions (p. 45) for details.

To transfer your system from an MBR disk to a UEFI-booted computer:
1. Boot from the Acronis bootable media in UEFI mode and select Acronis True Image. 2. Run the Recovery wizard and follow the instructions described in Recovering your system (p. 89). 3. On the What to recover step, select the check box next to the disk name to select the entire
system disk. In the example below, you need to select the Disk 1 check box:

4. On the Finish step, click Proceed. When the operation finishes, the destination disk is converted to GPT style so that it is bootable in UEFI.
After the recovery, please ensure that you boot your computer in UEFI mode. You may need to change the boot mode of your system disk in the user interface of the UEFI boot manager.
5.1.4 Arranging boot order in BIOS or UEFI BIOS
To boot your computer from Acronis bootable media, you need to arrange boot order so the media is the first booting device. The boot order is changed in BIOS or UEFI BIOS, depending on your computer firmware interface. The procedure in both cases is very similar.

100

Copyright © Acronis International GmbH, 2003-2020

To boot from Acronis bootable media:
1. If you use a USB flash drive or external drive as a bootable media, plug it into the USB port. 2. Turn your computer on. During the Power-On Self Test (POST), you will see the key combination
that you need to press in order to enter BIOS or UEFI BIOS. 3. Press the key combination (such as, Del, F1, Ctrl+Alt+Esc, Ctrl+Esc). The BIOS or UEFI BIOS setup
utility will open. Note that utilities may differ in appearance, sets of items, names, etc.
Some motherboards have a so-called boot menu opened by pressing a certain key or key combination, for instance, F12. The boot menu allows selecting the boot device from a list of bootable devices without changing the BIOS or UEFI BIOS setup.
4. If you use a CD or DVD as a bootable media, insert it in the CD or DVD drive. 5. Make your bootable media (CD, DVD or USB drive) device the first booting device:
1. Navigate to the Boot order setting by using the arrow keys on your keyboard. 2. Place the pointer on the device of your bootable media and make it the first item in the list.
You can usually use the Plus Sign and the Minus Sign keys to change the order.

6. Exit BIOS or UEFI BIOS and save the changes that you made. The computer will boot from Acronis bootable media.
If the computer fails to boot from the first device, it tries to boot from the second device in the list, and so on.
5.2 Recovering files and folders
You can recover files and folders both from file-level and disk-level backups.
To recover files and folders: 1. Start Acronis True Image 2021. 2. On the sidebar, click Backup. 3. From the backup list, select the backup which contains the files or folders that you want to
recover, and then open the Recovery tab. 4. Select backup version (data state on specific date and time).

101

Copyright © Acronis International GmbH, 2003-2020

5. Select the files and folders that you want to recover, and click Next.

6. Select a destination on your computer to where you want to recover the selected files/folders. The selected items will be recovered without recovering the original, absolute path.
7. When needed, set the options for the recovery process (recovery process priority, file-level security settings, etc.). To set the options, click Recovery options. The options you set here will be applied only to the current recovery operation.
8. To start the recovery process, click the Recover now button. You can stop the recovery by clicking Cancel. Please keep in mind that the aborted recovery may still cause changes in the destination folder.
Recovering files in File Explorer
To recover files and folders directly from File Explorer:
1. Double-click the corresponding .tib file, and then browse to the file or folder that you want to recover.
2. Copy the file or folder to a hard disk.
Note The copied files lose the "Compressed" and "Encrypted" attribute. If you need to keep these attributes, it is recommended to recover the backup.
5.3 Searching backup content
While recovering data from local backups, you can search for specific files and folders stored in the selected backup.
To search for files and folders:
1. Start recovering data as described in Recovering partitions and disks (p. 96) or Recovering files and folders (p. 101).

102

Copyright © Acronis International GmbH, 2003-2020

2. When selecting files and folders to recover, enter the file or folder name into the Search field. The program shows search results.
You can also use the common Windows wildcard characters: * and ?. For example, to find all files with extension .exe, enter *.exe. To find all .exe files with names consisting of five symbols and starting with "my", enter My???.exe.

3. By default, Acronis True Image 2021 searches the folder selected on the previous step. To include the entire backup in the search, click the down arrow, and then click in entire backup. To return to the previous step, delete the search text, and then click the cross icon.
4. After the search is complete, select the files that you want to recover, and then click Next.
Note: Pay attention to the Version column. The files and folders that belong to different backup versions cannot be recovered at the same time.
5.4 Recovery from Acronis Cloud
5.4.1 Recovering data from online backups

To recover files and folders from Acronis Cloud:
1. Start Acronis True Image 2021. 2. On the sidebar, click Account. 3. In the Account page, click Open Online Dashboard.
You are redirected to the Acronis Cyber Cloud browser page. 4. On the panel to the right, click BACKUPS.

104

Copyright © Acronis International GmbH, 2003-2020

5. From the Backups list, select the cloud backup which contains the files or folders that you want to recover.
6. From the list of files and folders, select the ones that you want to recover. 7. DOWNLOAD to start the recovery on the sidebar.
If you selected several files and folders, they will be placed into a zip archive.
5.4.2 Recovering a file version
By default Acronis True Image 2021 selects the latest versions with respect to the date you specified. However, for any file you can select a specific version of the file to recover.
Note that this option is not applicable to folders.
To recover a specific file version: 1. In the backup contents, select the file which version you want to recover, then click the gear icon
at the right-hand side. Select View versions in the opened menu. 2. In the window that appears, point to the required version, and then click the Download icon.

By default the data will be downloaded to the Downloads folder.
5.4.3 Disk recovery from Cloud
Disk recovery from Acronis Cloud is very similar to the recovery from an ordinary hard disk drive.  When you can start Windows and Acronis True Image 2021, please refer to Recovering partitions
and disks (p. 96).  When Windows cannot start, please refer to Recovering your system from Acronis Cloud (p. 106).
How it works
Your computer should be connected to the Internet either by an Ethernet cable or via Wi-Fi. Acronis True Image 2021 supports several wireless security protocols, including WPA-Personal, WPA2-Personal, and WPA2-Enterprise.
Recovery to the original location
When you recover a disk to the original location, Acronis True Image 2021 does not download the entire disk space to your computer. It scans your disk searching for data changes and recovers only those files that are different from files in the image. This technology significantly reduces the amount of data you need to download in order to recover your disk.

105

Copyright © Acronis International GmbH, 2003-2020

Recovery to a new location
When you recover a disk to a different location or to an unallocated space, the process is very similar to a recovery from a local storage. The only difference is in the data writing method. Acronis True Image downloads and writes data by separate blocks, and not continuously. This technology increases recovery speed and reliability of the entire process.
What if recovery has been interrupted
Since disk recovery from Acronis Cloud uses an Internet connection and usually takes a long time, the probability of the recovery interruption is higher comparing to recovery from an ordinary hard disk.
Possible reasons of recovery interruption:  Internet connection has been lost.  Connection to Acronis Cloud has been lost.  You canceled the recovery, deliberately or accidentally.  Electricity supply problem. When recovery is not complete due to a connection problem, Acronis True Image 2021 automatically tries to reconnect to Acronis Cloud and resume the recovery process. It is recommended that you check your Internet connection settings in this case. If all the automatic attempts fail, run the recovery again manually when connection is restored.
In other cases please run recovery again manually and make sure the recovery is complete.
Regardless of an interruption reason, Acronis True Image 2021 does not start recovery from the very beginning. It resumes the process and downloads only the data that was not recovered.
5.4.3.1 Recovering your system from Acronis Cloud
Depending on your Internet connection speed, disk recovery from Acronis Cloud may take a long time.
Before you start, we recommend that you complete the preparations described in Preparing for recovery (p. 88). If you recover your system to a new disk, you do not need to format the new disk, as this will be done in the process of recovery.
Before starting this procedure, please make sure that your computer is connected to the Internet by an Ethernet cable or over Wi-Fi.
To recover a system disk from Acronis Cloud:
1. Arrange the boot order in BIOS so as to make your Acronis bootable media (CD, DVD or USB stick) the first boot device. See Arranging boot order in BIOS (p. 100).
2. Boot from the bootable media and select Acronis True Image.

To delete a criterion, select it in the list, and then click the minus sign.
5.6.7 Performance of recovery operation
Location: Recovery options > Advanced > Performance
You can configure the following settings:
Operation priority
Changing the priority of a backup or recovery process can make it run faster or slower (depending on whether you raise or lower the priority), but it can also adversely affect the performance of other running programs. The priority of any process running in a system, determines the amount of CPU usage and system resources allocated to that process. Decreasing the operation priority will free more resources for other CPU tasks. Increasing backup or recovery priority may speed up the process by taking resources from the other currently running processes. The effect will depend on total CPU usage and other factors.
You can set up the operation priority:  Low (enabled by default) - the backup or recovery process will run slower, but the performance
of other programs will be increased.  Normal - the backup or recovery process will have the equal priority with other processes.  High - the backup or recovery process will run faster, but the performance of other programs will
be reduced. Be aware that selecting this option may result in 100% CPU usage by Acronis True Image 2021.
5.6.8 Notifications for recovery operation
Location: Recovery options > Notifications
Sometimes a backup or recovery procedure can last an hour or longer. Acronis True Image 2021 can notify you when it is finished via e-mail. The program can also duplicate messages issued during the operation or send you the full operation log after operation completion.
By default all notifications are disabled.

112

Free disk space threshold
You may want to be notified when the free space on the recovery storage becomes less than the specified threshold value. If after starting a backup Acronis True Image 2021 finds out that the free space in the selected backup location is already less than the specified value, the program will not begin the actual recovery process and will immediately inform you by displaying an appropriate message. The message offers you three choices - to ignore it and proceed with the recovery, to browse for another location for the recovery or to cancel the recovery.
If the free space becomes less than the specified value while the recovery is being run, the program will display the same message and you will have to make the same decisions.
To set the free disk space threshold:  Select the Show notification message on insufficient free disk space check box  In the Size box, type or select a threshold value and select a unit of measure
Acronis True Image 2021 can monitor free space on the following storage devices:  Local hard drives  USB cards and drives  Network shares (SMB)

6 Archiving data

In this section What is data archiving?................................................................................................... 115 What is excluded from archives? .................................................................................... 116 Cloud archiving vs. Online backup .................................................................................. 116 Archiving your data ......................................................................................................... 117 Accessing your archived files .......................................................................................... 118

6.1 What is data archiving?
Data archiving is a tool that allows you to move your big or rarely used files to Acronis Cloud, NAS, an external hard drive, or a USB flash drive. Every time you run this tool, it analyzes the data in the selected folder and suggests uploading the found files to Acronis Cloud or moving them to local storage. You can select the files and folders that you want to archive. After moving to an archive, the local copies of these files will be deleted. The links to the files are stored in a special location called Acronis Drive. You can access the location as an ordinary folder in File Explorer. Double-clicking a file link will open the file as if it was stored in the local folder. If the file is archived to Acronis Cloud, it will be downloaded back to your computer, first. You can also access and manage it right in Acronis Cloud.
Data archiving has the following main features:
 Free storage space saving
As a rule, storage space of modern high-capacity hard drives is mostly occupied by user data, such as photographs and documents, and not by the operating system or applications. Since most of the data is used occasionally, there is no need to keep them on a local drive. Data archiving helps you free up storage space for frequently used files.  Cloud archiving and local archiving
You can choose a destination type for your archive: Acronis Cloud or local storage, such as an internal hard drive, external hard drive, NAS, or a USB flash drive. Every time you choose Acronis Cloud as a destination, the selected data is stored in the same cloud archive. Local archives are independent from each other and may have different names, destinations, encryption settings, and so on, though you can select an existing archive as a destination instead of creating a new one. The number of local archives is not limited.  Easy access of cloud archive from any device
When you archive your files to Acronis Cloud, you can access them with Acronis True Image 2021, the Acronis True Image mobile application, and the Acronis Cloud web application from any device running Windows, Mac OS X, iOS, and Android, including tablets and smartphones.  Data protection in the cloud archive
Your data stored in Acronis Cloud is protected from corruption or disaster. For example, in case of your local hard drive failure, you can download your files to your new hard drive. Moreover, your data is stored in encrypted state. You can be sure that no one except you can access your data.  File sharing
When your files are uploaded to Acronis Cloud, you can create public links to share the files with your friends or to post them to forums and social networks.  File versions

115

Copyright © Acronis International GmbH, 2003-2020

For the files that have been changed and uploaded to Acronis Cloud several times, Acronis True Image 2021 keeps all the modifications in different file versions. You can choose a previous file version and download it to your device.
6.2 What is excluded from archives?
To reduce archive size and eliminate a possibility to corrupt your system, by default Acronis True Image 2021 excludes the following data from archives:
 pagefile.sys  swapfile.sys  The Temp folder  The System Volume Information folder  The Recycle Bin  Web browser temporary data:
 Temporary Internet files  Cache  .tib files  .tib.metadata files  .tmp files  .~ files
See the full file list in the Knowledge Base article: https://kb.acronis.com/content/58297.

6.3 Cloud archiving vs. Online backup

When you archive your data to Acronis Cloud, it is similar to an online backup, but there are a number of differences.

Online backup

Cloud archiving

Feature purpose Data protection

Data protection from operating system corruption, hardware failures, and loss of separate files.
 Overall protection of all data on a
computer, especially an operating system.
 Protection of frequently used files.

Cleanup of local storage device and moving data to Acronis Cloud.
Protection of rarely used and old files, mostly your personal documents, photographs, and so on.

Source data selection Manual selection.

Manual selection of automatically found files.

Source data handling

The source data is kept in the original location.

The source data is deleted from the original location. This gives you a guarantee that your data will not get into the wrong hands if your hard drive or laptop is stolen.

Data change frequency The data to back up is changed frequently. Usually a backup has many versions updated from time to time.

The data to archive is changed rarely. The files have few versions.

6.4 Archiving your data
Data archiving helps you free up your storage space by moving your old or rarely used files to Acronis Cloud or local storage. Refer to What is data archiving (p. 115) for details.
To archive your data:
1. Start Acronis True Image 2021, and then go to the Archive section. 2. [Optional step] To learn basics of the data archiving feature, view the Getting Started slides. 3. Do one of the following:
 To analyze files in your default Windows user folder, usually located at C:\Users\[username], click Analyze Home folder.
 To analyze files in a custom folder, click the down-arrow, click Select different folder, and then select the folder to analyze.
Acronis True Image 2021 analyzes files on your computer. Note that this process may take several minutes. 4. In the left area, select a data category. Then, in the right area, select the files and folders that you want to archive. When selecting found files, you can sort them, for example, by size or by age (last modified date). To sort the files, click the appropriate column header. 5. Click Select destination, and then select Acronis Cloud or a custom local destination for the archived files. 6. [optional step] Click Options to set the options for the archive, including Data center and Encryption. Refer to Data archiving options (p. 117) for details. 7. Click Archive. 8. Confirm that you want to move your files to the archive and automatically delete them from your computer.
Additionally, watch the English-language video instructions at https://goo.gl/eEkNj2.
6.4.1 Data archiving options
Data center
When you archive your files to Acronis Cloud, they are uploaded to one of the Acronis data centers located in different countries. Initially, the data center is defined as the one closest to your location when you create your Acronis account. Afterwards, your archived files are stored in the same data center, by default.
We recommend that you set the data center for an archive manually, when you are in a different country and your default data center is not the closest to your current location. This will significantly increase the data upload rate.
Note: You cannot change the data center after starting the archiving process.
To select a data center:
1. When configuring the first archiving process, click Options. 2. Select the country that is closest to your current location.

117

Copyright © Acronis International GmbH, 2003-2020

Encryption
To protect the archived data from unauthorized access, you can encrypt the archive with industry-standard AES (Advanced Encryption Standard) cryptographic algorithm with a 256-bit long key.
Note: You cannot set or change the archive encryption option for a pre-existing archive.
To encrypt an archive:
1. When configuring the first archiving process, click Options. 2. Select the Encrypt archive by using the AES-256 algorithm check box. 3. Enter the password for the archive into the corresponding field. We recommend that you use a
password longer than seven symbols and containing both letters (in upper and lower cases preferably) and numbers to make it more difficult to guess.
A password cannot be retrieved. Please memorize the password that you specify for an archive protection.
Acronis True Image asks for the password every time you try to modify the archive. To access the archive, you must specify the correct password.
6.5 Accessing your archived files
When your files are successfully archived, you can access them in:  File Explorer
Start File Explorer, and then click Acronis Drive under Favorites. You can work with the files in read-only mode. To modify a file, copy it to a different folder, first.  Acronis Cloud (applicable to the cloud archive only) Open the Acronis Cloud web application in one of the following ways:  Start Acronis True Image 2021, click Archive, and then click In your web browser.  Go to https://www.acronis.com/my/online-backup/webrestore/, and then log in to your
account.

8 Antivirus and antimalware protection
Acronis True Image 2021 provides two types of antivirus and antimalware protection.  Active Protection runs constantly in the background to protect your machines in real time while
you work as usual.  Antivirus scans run on-demand to perform in-depth search for malicious software throughout
the whole system.
Note You can turn the protection on or off in the True Image UI only. You cannot stop the process manually through Task Manager or any other external tool.
The Protection dashboard
The Protection dashboard contains statistical data on the Active protection and the Antivirus scan processes, provides control over the protection status, and access to the protection setting.
To access the Protection dashboard, click Protection on the sidebar of the Acronis True Image 2021 interface.

On the Overview tab of the dashboard, you can:
 View statistics about the active protection status.  View the number of detected issues, quarantined, and excluded items.  View the latest report of the Antivirus scan.  View the next scheduled scan time.  Manually run full or quick Antivirus scan. To do this, click Run full scan or Run quick scan.  Pause the entire Protection for a predefined period of time (30 minutes, 1 hour, 4 hours, until
restart). To do this, click Pause and choose the period.

123

Copyright © Acronis International GmbH, 2003-2020

Note By pausing the protection, you deactivate Active Protection (Real-time protection, Antiransomware protection, and Web filtering). Scheduled on-demand scans will not start.
On the Activity tab of the dashboard, you can view a log of the changes that you applied to your protection status and settings.

In this section Active protection............................................................................................................. 124 Antivirus scans ................................................................................................................ 128 Managing detected issues .............................................................................................. 129 Managing files in Quarantine.......................................................................................... 130 Configuring Protection exclusions .................................................................................. 130 Protection for Zoom, Cisco Webex, and Microsoft Teams ............................................. 131 Downloading Protection updates ................................................................................... 131

8.1 Active protection
To protect your computer from malicious software in real-time, Acronis True Image 2021 uses the Acronis Active Protection technology.
Active Protection constantly checks your computer for ransomware, cryptomining processes, viruses and other malicious threats, and provides Web filtering while you continue working as usual. In addition to your files, Acronis Active Protection protects the Acronis True Image application files, your backups, archives, and the Master Boot Records of your hard drives.
Active protection consists of several protection levels that you can enable independently from each other:  Anti-ransomware protection  Real-time protection  Web filtering
Antiransomware protection
Ransomware encrypts files and demands a ransom for the encryption key. Cryptomining malware performs mathematical calculations in the background, thus stealing the processing power and network traffic of your machine.
When the Antiransomware Protection service is on, it monitors in real time the processes running on your computer. When it detects a third-party process that tries to encrypt your files or mine cryptocurrency, the service informs you about it and asks if you want to allow the process to continue or to block the process.
To allow the process to continue the activity, click Trust. If you are not sure if the process is safe and legal, we recommend that you click Quarantine. After this, the process will be added to Quarantine and blocked from any activities.
Recovering your files after blocking a process
After blocking a process, we recommend that you check if your files have been encrypted or corrupted in any way. If they are, click Recover modified files. Acronis True Image 2021 will search the following locations for the latest file versions to recover.  Temporary file copies that were preliminarily created during the process verification  Local backups

124

Copyright © Acronis International GmbH, 2003-2020

 Cloud backups
If Acronis True Image 2021 finds a good temporary copy, the file is restored from that copy. If temporary file copies are not suitable for restore, Acronis True Image 2021 searches for backup copies locally and in the cloud, compares the creation dates of the copies found in both locations, and restores your file from the latest available non-corrupt copy.
Note Acronis True Image 2021 does not support file recovery from password-protected backups.
To configure Acronis True Image 2021 to automatically recover files after blocking a process, select the Automatically recover files after blocking a process check box in the Active Protection settings. See Configuring Active Protection (p. 126).
Real-time Protection
When Real-time Protection is enabled, it constantly checks the files you interact with to protect your machine from suspicious activity, viruses, and other malicious threats in real time.
Real-time Protection comes with the following additional protection options:
 Behavior analysis ­ to identify malicious processes, Active Protection uses behavioral heuristics. It compares the chain of actions performed by a process with the chains of events recorded in the database of malicious behavior patterns. This approach enables Active Protection to detect new malware by its typical behavior.
 Exploit prevention ­ Active Protection analyzes the behavior of processes running on the machine and detects abnormal activity. It prevents infected processes from spreading and exploiting the vulnerabilities of other software installed on the system. Active Protection employs several exploit prevention methods:  Memory protection detects and prevents suspicious modifications of the execution rights on memory pages. Malicious processes apply such modifications to page properties, to enable the execution of shellcodes from non-executable memory areas like stack and heaps.  Privilege escalation protection detects and prevents attempts for elevation of privileges made by an unauthorized code or application. Privilege escalation is used by malicious code to gain full access of the attacked machine, and then perform critical and sensitive tasks. Unauthorized code is not allowed to access critical system resources or modify system settings.  Code injection protection detects and prevents malicious code injection into remote processes. Code injection is used to hide malicious intent of an application behind clean or benign processes, to evade detection by antimalware products.
You can choose one of the following types of scanning:
 Smart on-access detection means that the program runs in the background and actively and constantly scans your machine system for viruses and other malicious threats for the entire duration that your system is powered on. Malware will be detected in both cases when a file is being executed and during various operations with the file such as opening it for reading/editing.
 On execution detection means that only executable files will be scanned at the moment they are run to ensure they are clean and will not cause any damage to your machine or data. Copying of an infected file will remain unnoticed.
You can view the results of real-time protection checks in the Activity tab of the Protection dashboard.

125

Copyright © Acronis International GmbH, 2003-2020

Web filtering
Malware is often distributed by malicious or infected sites and uses the so called "Drive-by download" method of infection.
Web filtering helps to protect you from potentially harmful websites and untrusted web resources by blocking the access when you try to open them. To determine which websites are potentially harmful, Web filtering uses the Protection updates database. The Web filtering database also includes information about websites that contain fake news, scam, and phishing URLs. You can modify the rules defined in the database by configuring exclusions to the Web filtering list.
Easily configure URL exclusions through the product interface.
Web filtering has two modes of operation:  Complete block--the access to the website will be completely blocked.  Notify only--a notification will be displayed, but users will be able to access the website.

8.2 Antivirus scans
Antivirus scan is one of the components of Acronis True Image 2021 Antivirus and antimalware protection. It protects your computer by checking for malware on demand ­ manually or at predefined intervals that you can configure.
You can select between two types of scans.  Full scan checks the entire machine for viruses. Full scan will detect malware by examining all
files and processes (or a subset of files and processes), except for excluded files or folders that you defined in the excludes lists.  Quick scan checks only specific files and folders. Quick scan will detect malware by examining specific folders which are considered the most likely virus storages.
You can also choose what to scan: archive files, external drives, or only new and changed files.
Sometimes, the system might be shut down before the Antivirus scan is completed. For such cases, you can configure Acronis True Image 2021 to resume the scan when the system starts again. Moreover, Acronis True Image 2021 can prevent your computer from shutting down if a scan operation is running.
By default, when the CPU load is high, the priority of antivirus scans is decreased to let other applications perform properly. This results in slower scans. You can disable this option to speed up the scanning.
You can view the Antivirus scan results in the Scan details report.

9.1 About the Sync feature
The main highlights of the Sync feature:  You can have the same data - documents, photos, videos, etc. - on all of your computers. Your
data is within easy reach anywhere and anytime. No more emailing files to yourself or carrying a USB drive all the time.  You can create as many syncs as you need.  The Acronis Cloud keeps your synced files and versions of those files. This lets you roll back to a previous file version whenever you need it.
Note: An Acronis Cloud Storage subscription is required to use this feature. Refer to Subscription information for details.
 You can also access the Cloud using a web browser, without having to install our application.  When you create a sync between two or more computers directly, an Acronis Cloud subscription
is not required.
9.2 What you can and cannot synchronize
You can synchronize data stored in two or more folders. Let's consider where these folders may be located and what data they may contain.
Storage types
A synchronization process may be established between:  Two or more folders on two or more computers.  One or more computers and Acronis Cloud.
Acronis Cloud always contains the last versions of the synced files. At the same time you cannot select a folder on Acronis Cloud to participate in a sync, such folder is created automatically.
Within one sync process you may assign only one sync folder on every computer.
You cannot select for synchronization a single file. To synchronize the file, select for synchronization the folder that contains that file.
Data types
You can synchronize the following data:

132

10 Disk cloning and migration
This operation copies the entire contents of one disk drive to another disk drive. This may be necessary, for example, when you want to clone your operating system, applications, and data to a new, larger capacity disk. You can do it two ways:  Use the Clone disk utility (p. 138).  Back up your old disk drive, and then recover it to the new one (p. 92).
In this section Disk cloning utility ........................................................................................................... 138 Migrating your system from an HDD to an SSD .............................................................. 143
10.1 Disk cloning utility
The Clone disk utility allows you to clone your hard disk drive by copying the partitions to another hard disk.
Please read before you start:  When you want to clone your system to a higher-capacity hard disk, we recommend that you
install the target (new) drive where you plan to use it and the source drive in another location, e.g. in an external USB enclosure. This is especially important for laptops.
Note: It is recommended that your old and new hard drives work in the same controller mode (for example, IDE or AHCI). Otherwise, your computer might not start from the new hard drive.
Note: If you clone a disk with Windows to an external USB hard drive, you might not be able to boot from it. We recommend cloning to an internal SSD or HDD instead.
 The Clone disk utility does not support multiboot systems.  On program screens, damaged partitions are marked with a red circle and a white cross inside in
the upper left corner. Before you start cloning, you should check such disks for errors and correct the errors by using the appropriate operating system tools.  We strongly recommend that you create a backup of the entire original disk as a safety precaution. It could be your data saver if something goes wrong with your original hard disk during cloning. For information on how to create such a backup, see Backing up partitions and disks (p. 45). After creating the backup, make sure that you validate it.
10.1.1 Clone Disk wizard
Before you start, we recommend that you read general information about Disk cloning utility (p. 138).
If you use an UEFI computer and you decided to start the cloning procedure under bootable media, please pay attention to the boot mode of the bootable media in UEFI BIOS. It is recommended that the boot mode matches the type of the system in the backup. If the backup contains a BIOS system, then boot the bootable media in BIOS mode; if the system is UEFI, then ensure that UEFI mode is set.
To clone a disk:
1. Start Acronis True Image 2021. 2. On the sidebar, click Tools, and then click Clone disk.

138

Copyright © Acronis International GmbH, 2003-2020

3. On the Clone Mode step, choose a transfer mode.  Automatic--Recommended in most cases.  Manual--Manual mode will provide more data transfer flexibility. Manual mode can be useful if you need to change the disk partition layout.
If the program finds two disks, one partitioned and another unpartitioned, it will automatically recognize the partitioned disk as the source disk and the unpartitioned disk as the destination disk. In such case, the next steps will be bypassed and you will be taken to the cloning Summary screen.
4. On the Source Disk step, select the disk that you want to clone.

Acronis True Image 2021 does not support cloning of dynamic disks.
5. On the Destination Disk step, select the destination disk for the cloned data.
If the selected destination disk contains partitions, you will need to confirm deletion of the partitions. Note that the real data destruction will be performed only when you click Proceed on the last step of the wizard.
If any disk is unpartitioned, the program will automatically recognize it as the destination and bypass this step.
6. [This step is only available in the manual cloning mode]. On the Move method step, choose a data move method.  As is--a new partition will be created for every old one with the same size and type, file system and label. The unused space will become unallocated.  Proportional--the new disk space will be proportionally distributed between cloned partitions.  Manual--you will specify a new size and other parameters yourself.
7. [This step is only available in the manual cloning mode]. On the Change disk layout step, you can edit settings of the partitions that will be created on the destination disk. Refer to Manual partitioning (p. 141) for details.
8. [Optional step] On the What to exclude step, you can specify files and folders that you do not want to clone. Refer to Excluding items from cloning (p. 142) for details.

139

Copyright © Acronis International GmbH, 2003-2020

9. On the Finish step, ensure that the configured settings suit your needs, and then click Proceed.
If the cloning operation is stopped for some reason, you will have to configure and start the procedure again. You will not lose your data, because Acronis True Image does not alter the original disk and data stored on it during cloning. By default, Acronis True Image 2021 shuts down the computer after the clone process finishes. This enables you to change the position of master/subordinate jumpers and remove one of the hard drives.

140

Copyright © Acronis International GmbH, 2003-2020

10.1.2 Manual partitioning
The manual transfer method enables you to resize partitions on the new disk. By default, the program resizes them proportionally.

To edit a partition: 1. Select the partition, and then click Edit. This will open the Partition Settings window.

2. Specify the following settings for the partition:  Size and position  File system

141

Copyright © Acronis International GmbH, 2003-2020

 Partition type (available only for MBR disks)  Partition letter and label Refer to Partition settings (p. 170) for details. 3. Click Accept.
Be careful! Clicking any previous wizard step on the sidebar in this window will reset all size and location changes that you've selected, so you will have to specify them again.
10.1.3 Excluding items from cloning
If you do not want to clone specific files from a source disk (for example, when your target disk is smaller than the source one), you can opt to exclude them in the What to exclude step.
We do not recommend excluding hidden and system files when cloning your system partition.

You have two ways to exclude files and folders:
 Exclude by files and folders - this tab allows you to select specific files and folders from the folder tree.
 Exclude by masks - this tab allows you to exclude a group of files by mask or an individual file by name or path.
To add an exclusion criterion, click Add, type a file name, a path or a mask, and then click OK. You can add as many files and masks as you like.
Examples of exclusion criteria:
 You can enter explicit file names:  file.ext - all such files will be excluded from cloning.  C:\file.ext - the file.ext file on the C: disk will be excluded.
 You can use wildcard characters (* and ?):  *.ext - all files with a .ext extension will be excluded.

142

Copyright © Acronis International GmbH, 2003-2020

 ??name.ext - all files with a .ext extension, having six letters in their names (starting with any two symbols (??) and ending with name), will be excluded.
 You can enter path to a folder:  C:\my pictures - my pictures folder on the C: disk will be excluded.
You can edit and remove exclusion criteria using the corresponding buttons on the right pane.
10.2 Migrating your system from an HDD to an SSD
First of all, make sure that Acronis True Image 2021 detects your new SSD both in Windows and under the Acronis bootable media. If there is a problem, see What to do if Acronis True Image 2021 does not recognize your SSD (p. 143).
SSD size
As SSDs usually have less capacity than HDDs, the occupied space on your old hard disk may exceed the size of your SSD. If this is the case, migration is not possible.
To reduce amount of data on your system disk, try the following:  Move your data files from the old hard disk to another location, such as another hard disk drive,
internal or external.  Create .zip archives of data files (for example, your documents, pictures, audio files, etc.), and
then delete the original files.  Clean up the hard disk using the Windows Disk Cleanup utility. Note that for stable operation, Windows needs to have several GB of free space on the system partition.
Which migration method to choose
If your system disk consists of a single partition (not counting the hidden System Reserved partition), you can try to migrate to the SSD using the Clone tool. For more information see Cloning a hard disk (p. 138).
However, we recommend to use the backup and recovery method in most cases. This method provides more flexibility and control over migration. See Migrating to an SSD using the backup and recovery method (p. 144).
10.2.1 What to do if Acronis True Image 2021 does not recognize your SSD
Sometimes Acronis True Image 2021 may not recognize an SSD.
In such a case, check whether the SSD is recognized in BIOS.
If the BIOS of your computer does not show the SSD, verify that the power and data cables are properly connected. You may also try to update the BIOS and SATA drivers. If these suggestions do not help, contact the Support of your SSD manufacturer.
If the BIOS of your computer does show the SSD, you can try the following procedure:
Depending on your operating system, type cmd in the Search field or in the Run field, and then press Enter.

143

Copyright © Acronis International GmbH, 2003-2020

At the command line prompt type:
diskpart
list disk The screen will show the disks connected to your computer. Find out the disk number for your SSD. Use its size as the reference.
select disk N Here N is the disk number of your SSD.
clean This operation removes all information from the SSD and overwrites the MBR with the default one.
exit
exit
Start Acronis True Image 2021 and check whether it detects the SSD. If it detects the SSD, use the Add new disk tool to create a single partition on the disk occupying the entire disk space. When creating a partition, check that the free space before partition is 1 MB. For more information, see Adding a new hard disk (p. 167).
The next step is to check whether your Acronis bootable media recognizes the SSD. 1. Boot from the Acronis bootable media. 2. Select Tools & Utilities -> Add New Disk in the main menu and the Disk selection screen will
show the information about all hard disks in your system. Use this for checking whether the SSD is detected in the recovery environment. 3. If the screen shows your SSD, just click Cancel. If the bootable media does not recognize the SSD and the SSD controller mode is AHCI, you can try to change the mode to IDE (or ATA in some BIOS brands) and see whether this solves the problem.
Attention! Do not start Windows after changing the mode; it may result in serious system problems. You must return the mode to AHCI before starting Windows.
If after changing the mode the bootable media detects the SSD, you may use the following procedure for recovery or cloning under bootable media: 1. Shut down the computer. 2. Boot to BIOS, change the mode from AHCI to IDE (or ATA in some BIOS brands). 3. Boot from Acronis bootable media. 4. Recover or clone the disk. 5. Boot to BIOS and change IDE back to AHCI. 6. Start Windows.
What to do if the above suggestions do not help
You can try to create a WinPE-based media. This may provide the necessary drivers. For more information, see Creating Acronis bootable media (p. 148).
10.2.2 Migrating to SSD using the backup and recovery method
You can use the following procedure for all supported operating systems. First, let's consider a simple case: your system disk consists of a single partition. Note that for Windows 7 and later, the system disk may have a hidden System Reserved partition.

144

Copyright © Acronis International GmbH, 2003-2020

We recommend that you migrate your system to an empty SSD that does not contain partitions (the disk space is unallocated). Note that if your SSD is new and has never been used before, it does not contain partitions.
To migrate your system to an SSD:
1. Start Acronis True Image 2021. 2. Create Acronis bootable media, if you do not have it yet. To do this, in the Tools section, click
Create bootable media and follow the instructions on the screen. 3. Back up your entire system drive (in the disk backup mode) to a hard disk other than your system
hard disk and the SSD. 4. Switch off the computer and remove your system hard disk. 5. Mount the SSD into the slot where the hard disk was.
For some SSD brands you may need to insert the SSD into a PCI Express slot.
6. Boot from your Acronis bootable media. 7. Validate the backup to make sure that it can be used for recovery. To do this, click Recovery on
the left pane and select the backup. Right-click, select Validate Archive in the shortcut menu and then click Proceed. 8. After the validation finishes, right-click the backup and select Recover in the shortcut menu. 9. Choose Recover whole disks and partitions at the Recovery method step and then click Next. 10. Select the system disk at the What to recover step. 11. Click New location and then select the SSD as the new location for your system disk, then click Accept. 12. At the next step click Proceed to start recovery. 13. After the recovery is complete, exit the standalone version of Acronis True Image 2021. 14. Try to boot from the SSD and then make sure that Windows and applications work correctly.
If your system hard disk also contains a hidden recovery or diagnostic partition, as is quite often the case with notebooks, the procedure will differ. You will usually need to resize the partitions manually during recovery to the SSD. For instructions see Recovering a disk with a hidden partition (p. 92).

11.1 Acronis Media Builder
Acronis Media Builder allows you to make a USB flash drive, external drive, or a blank CD/DVD bootable. In case Windows cannot start, use the bootable media to run a standalone version of Acronis True Image and recover your computer.
You can create several types of bootable media:
 Acronis bootable media This type is recommended for most users.
 WinPE-based media with the Acronis plug-in Running Acronis True Image 2021 in the preinstallation environment may provide better compatibility with your computer's hardware because the preinstallation environment uses Windows drivers.
We recommend that you create this type of media, when Acronis bootable media did not help you boot your computer.
To use this option, you need one of the following components to be installed:  Windows Automated Installation Kit (AIK). This component is required for creating WinPE 3.0.  Windows Assessment and Deployment Kit (ADK). This component is required for creating WinPE 4.0, WinPE 5.0, and WinPE 10.0.
 WinRE-based media with the Acronis plug-in This type of bootable media is similar to WinPE-based media, but it has an important advantage--you do not need to download WADK or WAIK from the Microsoft website. Windows Recovery Environment is already included in Windows Vista and later versions of Windows. Acronis True Image 2021 uses these files from your system to create WinRE-based media. Similar to WinPE-based media, you can add your drivers for better compatibility with your hardware. However, WinRE-based media can be used only on the computer where it was created or on a computer with the same operating system.
Notes
 We recommend that you create a new bootable media after each Acronis True Image 2021 update.
 If you use non-optical media, the media must have a FAT16 or FAT32 file system.  Acronis Media Builder supports only x64 WinPE 3.0, WinPE 4.0, WinPE 5.0, and WinPE 10.0.  Your computer must have:
 For WinPE 3.0--at least 256 MB RAM  For WinPE 4.0--at least 512 MB RAM  For WinPE 5.0--at least 1 GB RAM

147

Copyright © Acronis International GmbH, 2003-2020

 For WinPE 10.0--at least 512 MB RAM  If Acronis Media Builder does not recognize your USB flash drive, you can try using the procedure
described in the Acronis Knowledge Base article at https://kb.acronis.com/content/1526.  When booting from the bootable media, you cannot perform backups to disks or partitions with
Ext2/Ext3/Ext4, ReiserFS, and Linux SWAP file systems.  When booting from the bootable media and using a standalone version of Acronis True Image
2021, you cannot recover files and folders encrypted with the encryption available in Windows XP and later operating systems. For more information, see File-level security settings for backup (p. 72). However, backups encrypted using the Acronis True Image 2021 encryption feature can be recovered.  If you decide to create a bootable media on a drive that already has a Survival Kit (p. 21), Acronis Media Builder will attempt to overwrite and update only the hidden partition with the bootable media without formatting the whole drive.

11.1.1 Creating Acronis bootable media
To create Acronis bootable media:
1. Plug in a USB flash drive, or an external drive (HDD/SSD), or insert a blank CD or DVD.
2. Start Acronis True Image 2021.
3. In the Tools section, click Rescue Media Builder.
4. Choose a creation method:  Simple--This is the easiest option. Acronis True Image will choose the optimal media type for your computer. If you use Windows 7 or a later version, WinRE-based media will be created.  Advanced--This option allows you to choose a media type. This means you can create the bootable media not only for your computer, but for a computer running a different Windows version. Refer to Acronis Media Builder (p. 147) for details.
If you select a Linux-based media, choose Acronis components to be placed on the media. Please ensure that the components that you select are compatible with the target computer architecture. Refer to Removable media settings (p. 71) for details.
If you select a WinRE-based or WinPE-based media, then:  Select an architecture type of the media--32-bit or 64-bit. Note that 32-bit bootable
media can work only on 32-bit computers, and 64-bit media is compatible with both 32-bit and 64-bit computers.  Select a toolkit that you want to be used for creating the bootable media. If you choose WAIK or WADK and you do not have the selected kit installed on your computer, then you first need to download it from the Microsoft website, and then install the required components--Deployment Tools and Windows Preinstallation Environment (Windows PE).
If you already have WinPE files on your computer and they are stored in a non-default folder, then just specify their location and the Acronis plug-in will be added to the existing WinPE image.  For better compatibility with your hardware, you can select drivers to be added to the media.
5. Select a destination for the media:  CD  DVD  External drive

148

Copyright © Acronis International GmbH, 2003-2020

 USB flash drive If your drive has an unsupported file system, Acronis True Image will suggest formatting it to FAT file system.
Warning! Formatting permanently erases all data on a disk.
 ISO image file You will need to specify the .iso file name and the destination folder. When the .iso file is created, you can burn it onto a CD or DVD. For example, in Windows 7 and later, you can do this by using a built-in burning tool. In File Explorer, double-click the created ISO image file, and then click Burn.
 WIM image file (available only for WinPE-based media) Acronis True Image adds the Acronis plug-in to the .wim file from Windows AIK or Windows ADK. You will need to specify a name for the new .wim file and the destination folder. To create a bootable media by using a .wim file, you first need to convert it to an .iso file. Refer to Creating an .iso file from a .wim file (p. 151) for details.
If Acronis Media Builder detects a previously created Acronis Survival Kit (p. 21) on this drive, it will attempt to overwrite and update only the hidden partition with the bootable media without formatting the whole drive.
6. Click Proceed.
11.1.2 Acronis bootable media startup parameters
Here, you can set Acronis bootable media startup parameters in order to configure the media boot options for better compatibility with different hardware. Several options are available (nousb, nomouse, noapic, etc.). These parameters are provided for advanced users. If you encounter any hardware compatibility problems while testing boot from the Acronis bootable media, it may be best to contact Acronis Technical Support.
To add startup parameters:  Enter a command into the Parameters field. You can type several commands, separated by
spaces.  Click Next to continue.
Additional parameters that can be applied prior to booting Linux kernel
Description
The following parameters can be used to load Linux kernel in a special mode:  acpi=off
Disables ACPI and may help with a particular hardware configuration.  noapic
Disables APIC (Advanced Programmable Interrupt Controller) and may help with a particular hardware configuration.  nousb
Disables loading of USB modules.  nousb2

149

Copyright © Acronis International GmbH, 2003-2020

Disables USB 2.0 support. USB 1.1 devices still work with this option. This option allows using some USB drives in USB 1.1 mode, if they do not work in USB 2.0 mode.  quiet
This parameter is enabled by default and the startup messages are not displayed. Deleting it will result in the startup messages being displayed as the Linux kernel is loaded and the command shell being offered prior to running the Acronis program.  nodma
Disables DMA for all IDE disk drives. Prevents kernel from freezing on some hardware.  nofw
Disables FireWire (IEEE1394) support.  nopcmcia
Disables PCMCIA hardware detection.  nomouse
Disables mouse support.  [module name]=off
Disables the module (e.g. sata_sis=off).  pci=bios
Forces to use PCI BIOS, and not to access the hardware device directly. For instance, this parameter may be used if the machine has a non-standard PCI host bridge.  pci=nobios
Disallows use of PCI BIOS; only direct hardware access methods are allowed. For instance, this parameter may be used if you experience crashes upon boot-up, probably caused by the BIOS.  pci=biosirq
Uses PCI BIOS calls to get the interrupt routing table. These calls are known to be buggy on several machines and they hang the machine when used, but on other computers it is the only way to get the interrupt routing table. Try this option, if the kernel is unable to allocate IRQs or discover secondary PCI buses on your motherboard.  vga=ask
Gets the list of the video modes available for your video card and allows selecting a video mode most suitable for the video card and monitor. Try this option, if the automatically selected video mode is unsuitable for your hardware.

11.1.3 Adding drivers to an existing .wim image
Sometimes a basic WinPE disk with Acronis Plug-in does not have drivers for your specific hardware, for example, for storage device controllers. The easiest way to add them is to select the Advanced mode in Rescue Media Builder (p. 148) and specify the drivers to add. You can add the drivers manually to an existing .wim file before creating an ISO file with Acronis Plug-in.
Attention! You can only add drivers which have the .inf filename extension.
The following procedure is based on an MSDN article that can be found at https://technet.microsoft.com/en-us/library/dd799244(WS.10).aspx

150

Copyright © Acronis International GmbH, 2003-2020

To create a custom Windows PE image, proceed as follows:
1. If you don't have the .wim file with the Acronis plug-in, start Rescue Media Builder and create it by choosing WIM file as a destination for the WinPE-based media. Refer to Creating Acronis bootable media (p. 148) for details.
2. Depending on your version of Windows AIK or Windows ADK, do one of the following:  In the Start menu, click Microsoft Windows AIK, right-click Windows PE Tools Command Prompt, and then select Run as administrator.  In the Start menu, click Microsoft Windows AIK, right-click Deployment Tools Command Prompt, and then select Run as administrator.  In the Start menu, click Windows Kits, click Windows ADK, right-click Deployment and Imaging Tools Environment, and then select Run as administrator.
3. Run the Copype.cmd script to create a folder with Windows PE files. For example, from a command prompt, type:
copype amd64 C:\winpe_x64
4. Copy your .wim file, for example, to folder C:\winpe_x64\. By default, this file is named AcronisBootablePEMedia.wim.
5. Mount the base image to a local directory by using the DISM tool. To do this, type:
Dism /Mount-Wim /WimFile:C:\winpe_x64\AcronisBootablePEMedia.wim /index:1 /MountDir:C:\winpe_x64\mount
6. Add your hardware driver, by using the DISM command with the Add-Driver option. For example, to add the Mydriver.inf driver located in folder C:\drivers\, type:
Dism /image:C:\winpe_x64\mount /Add-Driver /driver:C:\drivers\mydriver.inf
7. Repeat the previous step for each driver that you need to add. 8. Commit the changes by using the DISM command:
Dism /Unmount-Wim /MountDir:C:\winpe_x64\mount /Commit
9. Create a PE image (.iso file) from the resulting .wim file. Refer to Creating an .iso file from a .wim file for details.
11.1.4 Creating an .iso file from a .wim file
To create a bootable media by using a .wim file, you need to convert it to an .iso file first.
To create a PE image (.iso file) from the resulting .wim file:
1. Depending on your version of Windows AIK or Windows ADK, do one of the following:  In the Start menu, click Microsoft Windows AIK, right-click Windows PE Tools Command Prompt, and then select Run as administrator.  In the Start menu, click Microsoft Windows AIK, right-click Deployment Tools Command Prompt, and then select Run as administrator.  In the Start menu, click Windows Kits, click Windows ADK, right-click Deployment and Imaging Tools Environment, and then select Run as administrator.
2. Run the Copype.cmd script to create a folder with Windows PE files. For example, from a command prompt, type:
copype amd64 C:\winpe_x64
3. Replace the default boot.wim file in your Windows PE folder with the newly created .wim file (for example, AcronisBootablePEMedia.wim). If the AcronisBootablePEMedia.wim file is located on c:\, then:

151

Copyright © Acronis International GmbH, 2003-2020

For WinPE 3.0, type:
copy c:\AcronisBootablePEMedia.wim c:\winpe_x64\ISO\sources\boot.wim
For WinPE 4.0, WinPE 5.0 or WinPE 10.0, type:
copy "c:\AcronisBootablePEMedia.wim" c:\winpe_x64\media\sources\boot.wim
4. Use the Oscdimg tool. To create an .iso file, type:
oscdimg -n ­bc:\winpe_x64\etfsboot.com c:\winpe_x64\ISO c:\winpe_x64\winpe_x64.iso
Alternatively, to make the media bootable on both BIOS and UEFI computers, type:
oscdimg -m -o -u2 -udfver102 -bootdata:2#p0,e,bc:\winpe_x64\fwfiles\etfsboot.com#pEF,e,bc:\winpe_x64\fwfiles \efisys.bin c:\winpe_x64\media c:\winpe_x64\winpe_x64.iso
5. Burn the .iso file to a CD by using a third-party tool, and you will have a bootable Windows PE disc with Acronis True Image 2021.
11.2 Making sure that your bootable media can be used when needed
To maximize the chances of your computer's recovery, you must test that your computer can boot from the bootable media. In addition, you must check that the bootable media recognizes all of your computer's devices, such as the hard drives, mouse, keyboard, and network adapter.
If you purchased a boxed version of the product that has a bootable CD and you did not update Acronis True Image 2021, you can test this CD. Otherwise, please create a new bootable media. Refer to Creating Acronis bootable media (p. 148) for details.
To test the bootable media
If you use external drives for storing your backups, you must attach the drives before booting from the bootable CD. Otherwise, the program might not detect them.
1. Configure your computer to enable booting from the bootable media. Then, make your bootable media device (CD-ROM/DVD-ROM or USB drive) the first boot device. Refer to Arranging boot order in BIOS (p. 100) for details.
2. If you have a bootable CD, press any key to start booting from the CD, when you see the "Press any key to boot from CD" prompt. If you do not press a key within five seconds, you will need to restart the computer.
3. After the boot menu appears, choose Acronis True Image 2021.
If your wireless mouse does not work, try replacing it with a wired one. The same recommendation applies to the keyboard.

152

Copyright © Acronis International GmbH, 2003-2020

If you do not have a spare mouse or keyboard, contact Acronis Support. They will build a custom bootable CD that will have drivers for the models of your mouse and keyboard. Please be aware that finding the appropriate drivers and making the custom bootable CD may take some time. Furthermore, this may be impossible for some models.
4. When the program starts, we recommend that you try recovering some files from your backup. A test recovery allows you to make sure that your bootable CD can be used for recovery. In addition, you can make sure that the program detects all of the hard drives you have in your system.
If you have a spare hard drive, we strongly recommend that you try a test recovery of your system partition to this hard drive.
How to test recovery, as well as check the drives and network adapter
1. If you have file backups, start Recovery Wizard by clicking Recovery -> File Recovery on the toolbar.
If you have only disk and partition backup, Recovery Wizard also starts and the recovery procedure is similar. In such a case, you need to select Recover chosen files and folders at the Recovery Method step.

153

Copyright © Acronis International GmbH, 2003-2020

2. Select a backup at the Archive location step, and then click Next.
3. When recovering files with the bootable CD, you are able to select only a new location for the files to be recovered. Therefore, just click Next at the Location selection step.
4. After the Destination window opens, check that all of your drives are shown under My Computer.
If you store your backups on the network, verify that you can access the network. If no computers are visible on the network, but the Computers Near Me icon is found under My Computer, specify the network settings manually. To do this, open the window available at Tools & Utilities  Options  Network adapters.

154

Copyright © Acronis International GmbH, 2003-2020

If the Computers Near Me icon is not available under My Computer, there may be problems either with your network card or with the card driver provided with Acronis True Image 2021.

5. Select the destination for the files, and then click Next. 6. Select several files for recovery by selecting their check boxes and then click Next.

7. Click Proceed on the Summary window to start recovery. 8. After the recovery finishes, exit the standalone Acronis True Image 2021. Now, you can be reasonably sure that your bootable CD will help you when you need it.

155

11.2.1 Selecting video mode when booting from the bootable media
When booting from the bootable media the optimal video mode is selected automatically depending on the specifications of your video card and monitor. However, sometimes the program can select the wrong video mode, which is unsuitable for your hardware. In such case you can select a suitable video mode as follows:
1. Start booting from the bootable media. When the boot menu appears, hover the mouse over Acronis True Image 2021 item and press the F11 key.
2. When the command line appears, type "vga=ask" (without quotes) and click OK.

3. Select Acronis True Image 2021 in the boot menu to continue booting from the bootable media. To see the available video modes, press the Enter key when the appropriate message appears.
4. Choose a video mode you think best suitable for your monitor and type its number in the command line. For instance, typing 338 selects video mode 1600x1200x16 (see the below figure).

5. Wait until Acronis True Image 2021 starts and make sure that the quality of the Welcome screen display on your monitor suits you.
To test another video mode, close Acronis True Image 2021 and repeat the above procedure.

156

Copyright © Acronis International GmbH, 2003-2020

After you find the optimal video mode for your hardware, you can create a new bootable media that will automatically select that video mode.
To do this, start Acronis Media Builder, select the required media components, and type the mode number with the "0x" prefix (0x338 in our instance) in the command line at the "Bootable media startup parameters" step, then create the media as usual.
11.3 Acronis Startup Recovery Manager
How it works
The Acronis Startup Recovery Manager lets you start Acronis True Image 2021 without loading the operating system. With this feature, you can use Acronis True Image 2021 by itself to recover damaged partitions, even if the operating system won't boot. Unlike booting from Acronis removable media, you will not need a separate media or network connection to start Acronis True Image 2021.
Note: Acronis Startup Recovery Manager cannot be used on tablets running Windows.
How to activate
To activate Acronis Startup Recovery Manager: 1. Start Acronis True Image 2021. 2. In the Tools section, click All tools, and then double-click Activate Acronis Startup Recovery
Manager. 3. In the opened window, click Activate.

How to use
If a failure occurs, turn on the computer and press F11 when you see the "Press F11 for Acronis Startup Recovery Manager" message. This will start a standalone version of Acronis True Image 2021 that differs only slightly from the complete version.
How to deactivate
To deactivate Acronis Startup Recovery Manager:
1. Start Acronis True Image 2021. 2. In the Tools section, click All tools, and then double-click Activate Acronis Startup Recovery
Manager. 3. In the opened window, click Deactivate.

157

Additional information
Disk letters in standalone Acronis True Image 2021 might sometimes differ from the way Windows identifies drives. For example, the D: disk identified in the standalone Acronis True Image 2021 might correspond to the E: disk in Windows. The disk labels and information on partition sizes, file systems, drive capacities, their manufacturers, and model numbers can help in correctly identifying the disks and partitions.
You won't be able to use the previously activated Acronis Startup Recovery Manager if the Try&Decide is turned on. Rebooting the computer in the Try mode will allow you to use Acronis Startup Recovery Manager again.
Does Acronis Startup Recovery Manager affect other loaders?
When Acronis Startup Recovery Manager is activated, it overwrites the master boot record (MBR) with its own boot code. If you have any third-party boot managers installed, you will need to reactivate them after the Startup Recovery Manager has been activated. For Linux loaders (e.g. LiLo and GRUB), you might consider installing them to a Linux root (or boot) partition boot record instead of MBR before activating Acronis Startup Recovery Manager.
UEFI boot mechanism is different from the BIOS one. Any OS loader or other boot program has its own boot variable that defines a path to the corresponding loader. All loaders are stored on a special partition called EFI System Partition. When you activate Acronis Startup Recovery Manager in UEFI-booted system, it changes the boot sequence by writing its own boot variable. This variable is added to the list of variables and does not change them. Since all loaders are independent and do not affect each other, there is no need to change anything before or after activating Acronis Startup Recovery Manager.
11.4 Try&Decide
When you turn Try&Decide on, your computer is in the Try mode. After that you can perform any potentially dangerous operations without worrying that you might damage your operating system, programs or data. When you turn Try&Decide off, you decide if you want to apply the changes to your computer or you want to discard them.
When Try&Decide can help
We recommend that you turn Try&Decide on before you try to:  Change any system settings, when you are not sure how these changes may affect your
computer.  Install system updates, drivers, etc.  Install unfamiliar applications.  Open mail attachments from unknown senders.  Visit websites that might contain potentially troublesome content.

158

Copyright © Acronis International GmbH, 2003-2020

Please remember that if you download e-mail from a POP mail server, create new files or edit existing documents while in the Try mode, and then decide to discard your changes, those files, document changes, and mail will no longer exist. In this case, save the new files and edited documents, for example, to a USB flash drive and unplug it before discarding the changes.

How Try&Decide works after a computer restart
You can leave the Try&Decide turned on as long as you like, because this mode "survives" across reboots of your operating system.
When your computer reboots for whatever reason while working in the Try mode, before booting of the operating system starts, you will be shown a dialog offering you two choices ­ stop the mode and discard changes or continue working in the mode. This will allow you to discard the changes that have resulted in a system crash. On the other hand, if you reboot, for example, after installing an application, you can continue working in the Try mode after starting Windows.

159

Copyright © Acronis International GmbH, 2003-2020

Every "soft" reboot of your computer while in the Try mode results in adding up to 500 MB of Try&Decide's housekeeping data into the storage selected for storing virtual changes.

Limitations in using Try&Decide
If you use Windows 7, Windows 8 or Windows 10, please, be aware that in the Try mode the program may use free disk space quite intensively, even when your computer is idle. This is due to housekeeping activities such as indexing that run in the background.
Please note that while working in the Try mode you will experience slowing down of the system performance. Furthermore, the process of applying changes may take a long time, especially if you leave the Try mode turned on days on end.
Please be aware that Try&Decide cannot track changes in disk partitions, so you will be unable to use the Try mode for virtual operations with partitions such as resizing partitions or changing their layout. In addition, you must not use the Try&Decide and disk defragmentation or disk error checking utilities at the same time, because this can irreparably corrupt the file system, as well as make the system disk unbootable.
When the Try mode is started, you won't be able to use the previously activated Acronis Startup Recovery Manager. Rebooting the computer in the Try mode will allow you to use Acronis Startup Recovery Manager again.
Try&Decide and Nonstop Backup cannot work simultaneously. Starting the Try mode suspends Nonstop Backup. Nonstop Backup will resume after you stop the Try mode.
When the Try mode is started, you won't be able to use the "Hibernate" power saving mode.
Try&Decide cannot be used for protecting dynamic disks.
Try&Decide cannot work when a partition in your system is encrypted with BitLocker.
Try&Decide cannot protect Acronis Secure Zone or use it as a storage for the virtual changes.
11.4.1 Using Try&Decide
To use Try&Decide: 1. Start Acronis True Image 2021. 2. In the Tools section, click Try&Decide.

160

3. Set up the Try&Decide options, if necessary. Refer to Try&Decide options and notifications (p. 161) for details.
4. To start the Try mode, click the Try&Decide icon. The program starts tracking all changes made to the OS and files and temporarily stores all the changes on the selected disk.
5. Perform all the changes you wanted to try.
When the disk space in the location selected for storing virtual changes is minimal for applying the changes, the program asks you whether to apply or discard the changes. If you ignore the alert message, the program will automatically restart the system when the disk is full, and discard the changes.
6. To stop the Try mode, click the Try&Decide icon in the Try&Decide window.

7. Choose one of the following:  Select Apply changes if you want to keep the changes made to the system.  Select Apply changes with reboot if you want to speed up the applying process. When you click the button, Try&Decide restarts your computer and applies the changes during the reboot.  Select Discard changes if you want to return your system to the state it was in prior to turning on the Try mode.
If you have chosen Discard Changes and rebooted the computer with multiple operating systems installed, you won't be able to boot other operating systems except the one used for working in the Try mode. A second reboot will recover the original MBR and make other operating systems bootable.

11.4.2 Try&Decide options and notifications
You can change Try&Decide options in the Try&Decide window. To restore the default values of the settings, click Reset settings to default.
Protected partitions
To change this setting:

Copyright © Acronis International GmbH, 2003-2020

1. Click the partition letter next to the setting name. The Partition Selection window opens. 2. Select the partitions that you want to protect, and then click OK.
By default, Try&Decide protects the system partition (Disk C), though you may choose to protect any other partitions in your system.
Storage for virtual changes
To change this setting:
1. Click the partition letter next to the setting name. The Storage for Virtual Changes window opens.
2. Select the partition that you want to use as a storage for virtual changes, and then click OK. By default, Try&Decide saves the information to a free space on Disk C.
When choosing to protect more than one partition, you cannot select one of the partitions to be protected to store virtual changes. In addition, you cannot select an external hard disk drive.
Notifications
To change the default notification settings, click Change alert settings. The Settings window opens.  On free disk space remaining - If the amount of free space in the storage for virtual changes
becomes less than the specified value, the program displays a notification message.  On time elapsed since Try&Decide started - The program will notify you if Try&Decide has been
working for longer than the period of time that you specified.

11.4.3 Try&Decide: typical use cases
The Try&Decide feature can help you in various circumstances, for example:
Software evaluation
Sometimes it may be useful to turn on the Try mode before installing new software. For example, we recommend that you turn it on when you want to:
 Choose antivirus software. There are known cases when installation of antivirus software cripples functionality of some applications or they may even refuse to launch after antivirus installation. You can test a trial version of the antivirus. If you encounter any problems, discard the changes in your system and try antivirus software from another vendor.
 Install a trial version of a program. It is well known that the "Add or Remove Programs" component of the Windows Control Panel cannot give a complete guarantee of cleanly uninstalling applications. If you do not like the program that you installed, discard the changes in your system. In this case, you can be sure that Try&Decide removed the program without a trace.
 Install suspicious software. If you do not trust the vendor of the software that you want to install, or when the source of the software is unknown, turn on the Try mode before installing this software. If anything goes wrong, discard the changes made in the Try mode.
File recovery
You have accidentally deleted some files and then emptied the Recycle Bin. Then you have remembered that the deleted files contained important data and now you are going to try to undelete them using the appropriate software. However, sometimes you may do something wrong

162

Copyright © Acronis International GmbH, 2003-2020

while trying to recover deleted files, making things worse than before trying to recover them. So you can proceed as follows:  Turn on the Try mode.  Launch the file undelete utility.  After the utility scans your disk in search of the deleted file or folder entries, it will present you
the deleted entries it has found (if any) and offer you the opportunity to save whatever it can recover. There is always a chance that you might pick the wrong file and while recovering it the utility may overwrite the very file you are trying to recover. If not for the Try&Decide, this error would be fatal and the file would be lost irretrievably.  But now you can just discard the changes made in the Try mode and make one more attempt to recover the files after turning on the Try mode again. Such attempts may be repeated until you are sure that you have done your best in trying to recover the files.
Web privacy
Suppose you do not want anybody to know, which Web sites you have visited or which pages you have opened - we all have the right to privacy. But the problem is that to make your Web surfing more comfortable and fast, the system stores this information and much more: cookies you have received, search engine queries you have made, URLs you have typed, etc. in special hidden files. And such information is not deleted completely when you clear your temporary Internet files, delete cookies, clear history of the recently opened Web pages using the browser's tools. So snoopers may be able to view the information using special software.
Turn on the Try mode and surf the Web as you please. Afterwards, if you want to remove all traces of your activity, discard the changes made in the Try mode.
11.5 Acronis Secure Zone
The Acronis Secure Zone is a special secure partition that you can create on your computer for storing backups. The Acronis Secure Zone has a FAT32 file system.
When you create an Acronis Secure Zone, it is displayed in the Other section of File Explorer. You can navigate through the Acronis Secure Zone as an ordinary partition.
If Acronis Secure Zone is password-protected, any operation, except viewing version details, requires entering the password.
Acronis Secure Zone cleanup
If there is not enough space in the Acronis Secure Zone for a new backup, you can:  Cancel the backup operation, increase the size of the Acronis Secure Zone, and then run the
backup again.  Cancel the backup operation, manually delete some backups in the Acronis Secure Zone, and
then run the backup again.  Confirm that you want to automatically delete the oldest backup of the same type (file-level or
disk-level) with all subsequent incremental and differential versions. After that, if free space is still insufficient, Acronis True Image asks for confirmation and will delete the next full backup. This will repeat until there is enough free space for the new backup. If after deleting all the previous backups there is still not enough space, the backup will be canceled.

163

Copyright © Acronis International GmbH, 2003-2020

To prevent the zone overflow, we recommended that you select the When not enough space in ASZ, delete the oldest backup check box in the scheduled backup options. Refer to Error handling (p. 71) for details.
You can use the Acronis Secure Zone as the storage for virtual system changes in the Try mode. The Try&Decide data will be automatically cleaned up after you stop a Try&Decide session.
Acronis True Image does not delete nonstop backup versions in the Acronis Secure Zone automatically. Such versions can only be deleted manually. For more information see Acronis Nonstop Backup data storage (p. 39).
11.5.1 Creating and managing Acronis Secure Zone
To create or modify the Acronis Secure Zone: 1. Click the Start button --> Acronis (product folder) --> True Image --> Tools and Utilities -->
Acronis Secure Zone. The Manage Acronis Secure Zone wizard opens. 2. Perform one of the following:  If you want to create the Acronis Secure Zone, specify its location (p. 164) and size (p. 165).  If you want to modify the Acronis Secure Zone, select an action:  Increase or decrease size (p. 164)  Remove (p. 167)  Change password (p. 166)
Then follow the wizard steps. 1. On the Finish step, click Proceed.
Note: This operation may require a computer restart.
11.5.2 Acronis Secure Zone location
Creating the Acronis Secure Zone
To specify a location for the Acronis Secure Zone:
1. Select a hard disk drive to create the Acronis Secure Zone on. 2. Select one or more partitions from which unallocated and/or free space will be taken. The
chosen partitions will be resized if necessary to give space to the Acronis Secure Zone.
The Acronis Secure Zone cannot be created on dynamic disks and volumes.

164

Copyright © Acronis International GmbH, 2003-2020

3. Click Next.

Increasing or decreasing the size of the Acronis Secure Zone
To increase/decrease the size of the Acronis Secure Zone: 1. Select the partitions from which space will be used to increase the size of the Acronis Secure
Zone, or that will receive free space after the size of the Acronis Secure Zone is reduced. You can also select partitions with unallocated space. 2. Click Next.
11.5.3 Size of Acronis Secure Zone
To specify the size of the Acronis Secure Zone:

165

Copyright © Acronis International GmbH, 2003-2020

Drag the slider to the appropriate position or type an exact value.

The minimum size is about 50 MB, depending on the geometry of the hard disk. The maximum size is equal to the disk's unallocated space plus the total free space on all partitions selected at the previous step.
When creating/enlarging the Acronis Secure Zone, the program will first use the unallocated space. If the unallocated space is not enough to achieve the desired size, the selected partitions will be decreased in size. Resizing of partitions may require the computer to be rebooted.
When reducing the size of the Acronis Secure Zone, if there is any unallocated space on the hard disk, it will be allocated to the selected partitions along with the space freed up from the Acronis Secure Zone. Thus, no unallocated space will remain on the disk.
Warning! Reducing a system partition to the minimum size may prevent your operating system from booting-up.
11.5.4 Acronis Secure Zone protection
You can set up password protection for the Acronis Secure Zone in order to prevent it from unauthorized access.
The program will ask for the password at any operation relating to the Acronis Secure Zone such as data backup and recovery, mounting images or validating backups in the Acronis Secure Zone, resizing and deleting the Acronis Secure Zone.
To set a password for the Acronis Secure Zone:
1. Select Set password. 2. Type the password in the Password field. 3. Retype the previously entered password in the Confirm field. 4. [Optional step] You can also select a secret question that will be asked in case you forget the
password. Select a secret question from the list and enter an answer to it.

166

Copyright © Acronis International GmbH, 2003-2020

5. Click Next to continue.

Acronis True Image 2021 repair or update will not affect the password. However, if the program is removed and then installed again while keeping the Acronis Secure Zone on the disk, the password to the Acronis Secure Zone will be reset.
11.5.5 Removing Acronis Secure Zone
Acronis Secure Zone deletion will automatically destroy all backups stored in the zone.
Select the partitions to which you want to add the space freed up from Acronis Secure Zone. If you select several partitions, the space will be distributed proportionally to each partition's size.
Also, you can choose to remove the Acronis Secure Zone while uninstalling the program.
11.6 Adding a new hard disk
If you do not have enough space for your data, you can either replace the old disk with a new higher-capacity one, or add a new disk only to store data, leaving the system on the old disk.
To add a new hard disk: 1. Shut down your computer, and then install the new disk. 2. Turn on your computer. 3. Click the Start button --> Acronis (product folder) --> True Image --> Tools and Utilities -->
Add New Disk. 4. Follow the wizard steps. 5. On the Finish step, ensure that the configured disk layout suits your needs, and then click
Proceed.

167

Copyright © Acronis International GmbH, 2003-2020

11.6.1 Selecting a hard disk
Select the disk that you have added to the computer. If you have added several disks, select one of them and click Next to continue. You can add the other disks later by restarting the Add New Disk Wizard.
If there are any partitions on the new disk, Acronis True Image 2021 will warn you that these partitions will be deleted.

168

Copyright © Acronis International GmbH, 2003-2020

11.6.2 Selecting initialization method
Acronis True Image 2021 supports both MBR and GPT partitioning. GUID Partition Table (GPT) is a new hard disk partitioning method providing advantages over the old MBR partitioning method. If your operating system supports GPT disks, you can select the new disk to be initialized as a GPT disk.

 To add a GPT disk, click Initialize disk in GPT layout.  To add an MBR disk, click Initialize disk in MBR layout.
After selecting the required initialization method click Next.
11.6.3 Creating new partitions
To use the space on a hard disk, it must be partitioned. Partitioning is the process of dividing the hard disk's space into logical divisions which are called partitions. Each partition may function as a separate disk with an assigned drive letter, its own file system, etc.
To create a new partition:
1. On the Partition creation step of the wizard, select the unallocated space, and then click Create new partition.
2. Specify the following settings for the partition being created:  Size and position  File system  Partition type (available only for MBR disks)  Partition letter and label Refer to Partition settings (p. 170) for details.

169

Copyright © Acronis International GmbH, 2003-2020

3. Click Accept.

11.6.3.1 Partition settings
Size
To resize the partition, perform one of the following:  Point to the partition border. When the pointer becomes a double-headed arrow, drag the
pointer to enlarge or reduce the partition size.  Type the desired partition size in the Partition Size field.
To relocate the partition, perform one of the following:  Drag the partition to a new position.  Type the desired size in either the Free space before or Free space after field.
When you create partitions, the program may reserve some unallocated space for system needs in front of the created partitions.
File System
You can either leave the partition unformatted, or choose between the following file system types:  NTFS is a native file system for Windows NT, Windows 2000, Windows XP, and later operating
systems. Choose it if you use these operating systems. Note, that Windows 95/98/Me and DOS cannot access NTFS partitions.  FAT 32 is an improved 32-bit version of the FAT file system that supports volumes up to 2 TB.  FAT 16 is a DOS native file system. Most operating systems recognize it. However, if your disk drive is more than 4 GB, it is not possible to format it in FAT16.  Ext2 is a Linux native file system. It is fast enough, but it is not a journaling file system.  Ext3 ­ officially introduced with Red hat Linux version 7.2, Ext3 is a Linux journaling file system. It is forwards and backwards compatible with Linux Ext2. It has multiple journaling modes, as well as broad, cross platform compatibility in both 32-bit and 64-bit architectures.

170

Copyright © Acronis International GmbH, 2003-2020

 Ext4 is a new Linux file system. It has improvements in comparison to ext3. It is fully backward compatible with ext2 and ext 3. However, ext3 has only partial forward compatibility with ext4.
 ReiserFS is a journaling file system for Linux. Generally it is more reliable and faster than Ext2. Choose it for your Linux data partition.
 Linux Swap is a swap partition for Linux. Choose it if you want to add more swap space using Linux.
Partition letter
Select a letter to be assigned to the partition. If you select Auto, the program assigns the first unused drive letter in alphabetical order.
Partition label
Partition label is a name, assigned to a partition so that you can easily recognize it. For example, a partition with an operating system could be called System, a data partition -- Data, etc. Partition label is an optional attribute.
Partition type (these settings are available only for MBR disks)
You can define the new partition as primary or logical.  Primary - choose this parameter if you are planning to boot from this partition. Otherwise, it is
better to create a new partition as a logical drive. You can have only four primary partitions per drive, or three primary partitions and one extended partition. Note: If you have several primary partitions, only one will be active at a time, the other primary partitions will be hidden and won't be seen by the OS.  Mark the partition as active - select this check box if you are planning to install an operating
system on this partition.  Logical - choose this parameter if you don't intend to install and start an operating system from
the partition. A logical drive is part of a physical disk drive that has been partitioned and allocated as an independent unit, but functions as a separate drive.
11.7 Security and Privacy Tools
11.7.1 Acronis DriveCleanser
Acronis DriveCleanser allows you to permanently destroy all data on selected hard disks and partitions. For the destruction, you can use one of the preset algorithms or create your own. Refer to Algorithm selection (p. 172) for details.
Why do I need it?
When you format your old hard drive before throwing it away, the information is not destroyed permanently and it can still be retrieved. This is a way that your personal information can end up in the wrong hands. To prevent this, we recommend that you use Acronis DriveCleanser when you:  Replace your old hard drive with a new one and do not plan to use the old drive any more.  Give your old hard drive to your relative or friend.  Sell your old hard drive.

Data destruction method
System Clean-up utilizes a number of the most popular data destruction methods. Here, you need to select the desired data destruction method.  Use common method - if you leave this parameter selected, the program will use the default
method (the initial setting is Fast method). If you need another destruction method to be set as a default, click on the corresponding link.  Use custom method for this component - selecting this parameter allows you to choose one of the preset data destruction methods from the drop-down list.
The data destruction methods are described in detail in Hard Disk Wiping Methods (p. 181) of this guide.
Files
The Files setting defines the names of files to clean with System Clean-up wizard and can be used with a search string.

Under the Windows operating system, a search string can represent a full or partial filename. A search string can contain any alphanumeric symbols, including commas and Windows wildcard symbols, and can have values similar to the following:  *.* ­ to clean all files with any file names and extensions.  *.doc ­ to clean all files with a specific extension ­ Microsoft document files in this case .  read*.* ­ to clean all files with any extensions, and names beginning with "read".  read?.* ­ to clean all files having five-letter names and any extensions, names beginning with
"read"; the fifth letter is random. The last search string, for example, will result in the removal of read1.txt, ready.doc files, but readyness.txt will remain with its longer name (excluding the extension)
You can enter several different search strings separated by semicolons; for example:
*.bak;*.tmp;*.~~~ (without spaces between the search strings)
All files with names corresponding to at least one of the search strings will be cleaned.

178

Copyright © Acronis International GmbH, 2003-2020

Upon entering the Files setting value, you can browse the files matching the search strings. To do this, click Show Files. You will see a window with the names of the found files. These files will be cleaned.
Drive free space
Here you can manually specify physical and/or logical drives to clean up free space on. By default, System Clean-up cleans up free space on all available drives.
If you want to change the settings of this parameter, you can use the Remove button to delete from the list the drives you don't need to clean free space on.
If you wish to add these drives to the list again, use the Add button.

Computers
The Computers setting is used for cleaning up the registry search strings you have used for finding computers in the local network. These strings keep information on what has interested you in the network. These items should also be deleted to maintain confidentiality.
The Computers setting is similar to the Files setting. It is a string that can contain any number of full or partial computer names separated by semicolons. The deletion of computer search strings is based on a comparison with the Computers setting value according to Windows rules.
If you simply need to delete all local network computer search strings (suitable in most cases), just leave the default value of this setting. To restore the default settings:  Select the Find Computer List component  Make sure the Enable check box is selected  Select the Computers setting; make sure its text box is clear.
As a result, all computer search strings will be deleted from the registry.
After entering the Computers setting value, you can browse the search strings found by the System Clean-up Wizard in the registry. To do so, click Show Computers. You will see the window with full and partial computer names searched for in the network. These items will be deleted.

"Commands" setting
Here you can select the commands to remove during Windows Run List clean-up.
This template can contain any command names or their parts separated by semicolons, e.g.:
*help; cmd; reg*
This will result in removing commands with names corresponding to or containing any of the names or parts of names you entered.

Network places filter
Here you can enter (separated by semicolons) any hostnames or IP addresses of network places, servers, FTP servers, network shares, etc. to which you have made connection by supplying network credentials (a user name and password).

 If required, you can dig deeper by expanding a component and selecting/unselecting its contents.
Having specified the components for clean-up, click the Clean-up button to continue.
Windows 7 and later operating systems do not store information on file and computer searches. Furthermore, information on opened/saved files is stored in the registry differently, so the wizard shows this information in a different way.

11.7.2.5 Clean-up progress
The operation status window reports about the state of the current operation.
The progress bar indicates the level of completion of the selected operation.
In some cases, the operation may take a long time to be completed. If this is the case, select the Shutdown the computer after completion check box. When the operation finishes, Acronis True Image 2021 will turn the computer off.

11.7.3 Hard Disk Wiping methods
What is the problem?
Information removed from a hard disk drive by non-secure means (for example, by simple Windows delete) can easily be recovered. Utilizing specialized equipment, it is possible to recover even repeatedly overwritten information.

Leakage mechanism
Data is stored on a hard disk as a binary sequence of 1 and 0 (ones and zeros), represented by differently magnetized parts of a disk.

Generally speaking, a 1 written to a hard disk is read as 1 by its controller, and 0 is read as 0. However, if you write 1 over 0, the result is conditionally 0.95 and vice versa ­ if 1 is written over 1 the result is 1.05. These differences are irrelevant for the controller. However, using special
equipment, one can easily read the «underlying» sequence of 1's and 0's.

Information wiping methods used by Acronis

The detailed theory of guaranteed information wiping is described in an article by Peter Gutmann. Please see "Secure Deletion of Data from Magnetic and Solid-State Memory" at https://www.cs.auckland.ac.nz/~pgut001/pubs/secure_del.html.

11.8 Mounting an image
Mounting images as virtual drives lets you access them as though they were physical drives. You can mount local backups that contain partitions or entire disk drives, and then select which partitions to mount. After mounting:  A new disk appears in your system for every mounted partition.  You can view the image contents in File Explorer and other file managers in read-only mode.
The operations described in this section are supported only for the FAT and NTFS file systems.
You cannot mount a disk backup, if it is stored on an FTP server.
How to mount an image
1. In File Explorer, right-click the image file that you want to mount, and then click Mount image. The Mount wizard opens.
2. Select the backup for mounting by its creation date/time. Thus, you can explore the data state at a certain moment.

182

Copyright © Acronis International GmbH, 2003-2020

3. [optional step] On the Drive letter step, select a letter to be assigned to the virtual disk from the Mount letter drop-down list. If you do not want to mount a partition, select Do not mount in the list or clear the partition's check box.
4. Click Proceed.
5. After the image is connected, the program will run File Explorer, showing its contents.

11.9 Unmounting an image
We recommend that you unmount the virtual disk after all necessary operations are finished, as maintaining virtual disks takes considerable system resources.
To unmount an image, perform one of the following:  In File Explorer, right-click the disk icon and click Unmount.  Restart or shut down your computer.

11.10 Working with .vhd(x) files
Acronis backups (.tib files) of disks or partitions can be converted to virtual hard disks (.vhd(x) files).
How to use .vhd(x) files  You can boot your computer from the converted .vhd(x) file to test whether the backup is valid
and can be recovered to a bootable operating system.  You can keep a converted .vhd(x) file for emergency situations. For example, if your computer
cannot start and you need to run it right away, you can boot from the .vhd(x) file.  In Windows 7, you can mount a .vhd(x) file as an additional drive. The .vhd(x) file may contain
any partitions ­ system or non-system.  You can run a converted .vhd(x) file as a virtual machine.
Limitations and additional information  A file backup cannot be converted to a .vhd(x) file.  To boot from a converted .vhd(x) file, it must contain:
 System partition of the same computer. You cannot boot other computers using the same .vhd(x) file.
 Windows 7 or later operating system.  Any changes you make to a booted or mounted .vhd(x) file are saved to it. If you boot from
a .vhd(x) file and make changes to the data that was not backed up, these changes will affect your live system.  The standalone versions of Acronis True Image 2021 that start when booting from the bootable media do not support conversion operations.  Acronis True Image 2021 cannot convert .tib files that contain dynamic volumes which were originally located on more than one disk drive (for example, spanned or striped dynamic volumes).

11.10.1 Converting Acronis backup
Users of the Enterprise and Ultimate editions of Windows 7 and later Windows versions can convert a .tib image of the system partition into the .vhd(x) format if they want to use the converted .vhd(x) file for booting the operating system. Or, they may want to get the ability to mount images without using Acronis True Image 2021.

183

Copyright © Acronis International GmbH, 2003-2020

To convert an Acronis disk image (.tib file) to a Windows backup (.vhd(x) file):
1. Start Acronis True Image 2021. 2. Go to the Backup section. 3. In the backup list, click the down arrow icon next to the backup that you want to convert, and
then click Convert to VHD. If the backup is password-protected, Acronis True Image 2021 will ask for it. Note that the resulting .vhd(x) file will lose password protection. 4. Select the backup version that you want to convert. Converting an incremental backup requires all the previous incremental backups and the original full backup. Converting a differential backup requires the original full backup. The result of conversion is always a full backup. 5. Specify the path to the file to be created. The file can be directed to any local storage supported by Acronis True Image 2021 (except the Acronis Secure Zone and CD/DVD). In addition, it can be directed to an SMB share. 6. [Optional step] While the backup is being converted, you can select the Start virtual machine after completion check box. If it is selected, Acronis True Image 2021 will restart your computer and run Hyper-V virtual machine by using the created .vhd(x) file.
When a .tib image selected for conversion contains partitions, for example, from two physical hard disk drives, the program will create two .vhd(x) files corresponding to those physical drives.
11.11 Importing and exporting backup settings
Acronis True Image 2021 allows you to import and export the settings of your backups. This may be desirable if you need to transfer the settings to a new PC after installing Acronis True Image 2021 on that computer. Saving the settings may also be useful if you later decide to upgrade to the next Acronis True Image 2021 version.
Such transfer will make configuring backups on the new PC much easier. You only need to export the settings and then import them to the other PC. The settings are exported in the form of script files.
The settings content can be different depending on a backup type. In case of "classic" disk and file type backups the settings consist of the following items:  list of items for backup  backup options  backup location  schedule  backup scheme  automatic clean-up rules  backup version naming rules
The settings of nonstop backup are as follows:  list of items for nonstop protection  Nonstop Backup data storage location (a list of locations, if there are several)
You cannot import online backup settings from one computer to another.
To export the backup settings:

184

Copyright © Acronis International GmbH, 2003-2020

1. Start Acronis True Image 2021. 2. On the sidebar, click Settings > Backup settings transfer, click Save settings to file, and then
browse for the destination to save the script files with the settings.
To import the backup settings:
1. Start Acronis True Image 2021 on another computer. 2. On the sidebar, click Settings > Backup settings transfer, click Import settings from file, and then
show the path to the script files with the settings.
After importing the settings you may need to change some of them to suit the new environment. For example, it may be necessary to change the list of items for backup, backup destination, etc.
If you want to copy some of your backups to another computer, it is recommended to export the settings of those backups too. Thus you will not lose some of the copied backup's functionality.
11.12 Acronis Universal Restore
Acronis Universal Restore allows you to create a bootable system clone on different hardware. Use this utility when recovering your system disk to a computer with a dissimilar processor, different motherboard or a different mass storage device than in the system you originally backed up. This may be useful, for example, after replacing a failed motherboard or when deciding to migrate the system from one computer to another.
What problem does it solve?
A system disk image can be restored easily on the hardware where it was created or to identical hardware. However, if you try to do it on a dissimilar hardware, the recovered system will fail to boot. This is because the new hardware is incompatible with critical drivers included in the image. The utility finds and installs drivers for devices that are critical for the operating system start-up, such as storage controllers, motherboard, or chipset.
How do I use it?
Before you start recovery to dissimilar hardware, ensure that you have:  Backup of your system disk (p. 45) or Entire PC backup (p. 20)  Acronis bootable media (p. 148)  Acronis Universal Boot media (p. 186)
If you have Acronis True Image 2021 and Acronis Universal Boot Media Builder installed on your computer, you can place both Acronis True Image 2021 and Acronis Universal Boot on the same media. Refer to Creating Acronis Universal Boot media (p. 186) for details.
To recover your system to dissimilar hardware:
1. Start your target computer by using Acronis bootable media, and then recover your system from your system backup or Entire PC backup. Refer to Recovering your system to a new disk under bootable media (p. 92) for details.
2. Start your target computer by using Acronis Universal Boot media, and then follow the on-screen instructions to make your system bootable. Refer to Using Acronis Universal Restore (p. 188) for details.

11.12.1 Creating Acronis Universal Boot media
Acronis Universal Boot media is used to make your computer bootable after recovery to dissimilar hardware. Refer to Acronis Universal Restore (p. 185) for details.
To create Acronis Universal Boot media:
1. Start Acronis True Image 2021. 2. In the Tools section, click Acronis Universal Restore. 3. Click Download to obtain Acronis Universal Boot Media Builder. 4. Run the downloaded file and install the media builder. 5. Plug in the USB flash drive or insert blank DVD that you want to make bootable. 6. To start Acronis Universal Boot Media Builder, perform one of the following:
 In the Tools section, click Acronis Universal Restore.  Click the Start button, open the list of installed programs, and then click Run Universal Boot
Media Builder. 7. Ensure that:
 Linux-based media is selected as a bootable media type.  Windows-like representation is selected as a way the disks and volumes are represented.

8. [Optional] Specify Linux kernel parameters. Refer to Bootable media startup parameters (p. 149) for details.

186

Copyright © Acronis International GmbH, 2003-2020

9. Select the Acronis components to place on the media.

You can select 32-bit and/or 64-bit components. The 32-bit components can work on 64-bit hardware. However, you need 64-bit components to boot a 64-bit computer that uses Unified Extensible Firmware Interface (UEFI).
To use the media on different types of hardware, select both types of components. When booting a machine from the resulting media, you will be able to select 32-bit or 64-bit components on the boot menu.
If Acronis True Image 2021 is installed on your computer, you can place it on the media as well. In this case, you will have a single bootable media containing both components required for recovery to dissimilar hardware.
10. Select a destination for the media:  CD  DVD  USB flash drive  ISO image file
You will need to specify the .iso file name and the destination folder.
When the .iso file is created, you can burn it onto a CD or DVD. For example, in Windows 7 and later, you can do this using a built-in burning tool. In File Explorer, double-click the created ISO image file, and then click Burn.
11. Specify the mass storage drivers to be used by Acronis Universal Boot.
You do not have to add the drivers now. You can do this later when you apply Acronis Universal Boot to a computer.
12. Click Proceed.
When the media is created, unplug it from your computer. This is your Acronis Universal Boot media.

11.12.2 Using Acronis Universal Restore
Preparation
Prepare drivers
Before applying Universal Restore to a Windows operating system, make sure that you have the drivers for the new HDD controller and the chipset. These drivers are critical to start the operating system. Use the CD or DVD supplied by the hardware vendor or download the drivers from the vendor's website. The driver files should have the *.inf, *.sys or *.oem extensions. If you download the drivers in the *.exe, *.cab or *.zip format, extract them using a third-party application.
Check access to the drivers in bootable environment
Make sure you have access to the device with drivers when working under bootable media. Use WinPE-based media if the device is available in Windows but Linux-based media does not detect it.
Universal Restore settings
Automatic driver search
Specify where the program will search for the Hardware Abstraction Layer (HAL), HDD controller driver and network adapter driver(s):  If the drivers are on a vendor's disc or other removable media, turn on the Search removable
media.  If the drivers are located in a networked folder or on the bootable media, specify the path to the
folder by clicking Add folder.
In addition, Universal Restore will search the Windows default driver storage folder (usually WINDOWS/inf).
Mass storage drivers to install anyway
You need this setting if:  The hardware has a specific mass storage controller such as RAID (especially NVIDIA RAID) or a
fibre channel adapter.  If the automatic drivers search does not help to boot the system.
Specify the appropriate drivers by clicking Add driver. The drivers defined here will be installed, with appropriate warnings, even if the program finds a better driver.
Universal Restore process
After you have specified the required settings, click OK.
When the process is complete, you will be able to configure the network connection and specify drivers for the video adapter, USB and other devices.

13 Glossary of Terms
A
Acronis Active Protection
A technology that protects data from ransomware, malicious software that blocks access to some files or an entire system and demands a ransom for unblocking. Based on a heuristic approach, this technology monitors processes on a computer in real-time mode and informs the user about attempts to encrypt data on the computer. In case files are encrypted, they can be recovered from the temporary copies or backups.
Acronis Drive
A virtual drive that contains both local and cloud archives (p. 196). The drive is accessible in File Explorer under Favorites and provides access to the archived files, in read-only mode.
Acronis Notary
A technology that allows user to check if a notarized file was modified since the time it was backed up. Acronis Notary calculates a hash code based on hash codes of the files selected for notarization, and then sends the hash code to a Blockchain-based database. The Blockchain technology guarantees that the hash code will not be changed. Therefore, the file authenticity can easily be verified by comparing the hash in the database and the hash of the file that you want to check.
Acronis Secure Zone
A secure partition for storing backups (p. 197) on a hard disk. Advantages:  enables recovery of a disk to the same
disk where the disk's backup resides  offers a cost-effective and handy method
for protecting data from software malfunction, virus attack, operator error

 eliminates the need for a separate media or network connection to back up or recover the data
Limitations:
1) The Acronis Secure Zone cannot be created on a dynamic disk.
2) The Acronis Secure Zone is not available as a location for backups in the recovery environment when you start Acronis True Image 2021 from bootable media, through Acronis Startup Recovery Manager or BartPE.
Acronis Startup Recovery Manager
A protection tool that allows to start standalone version of Acronis True Image 2021 at boot time when F11 is pressed. Acronis Startup Recovery Manager eliminates the need for bootable media.
Acronis Startup Recovery Manager is especially useful for mobile users. If a failure occurs, the user reboots the machine, hits F11 on prompt "Press F11 for Acronis Startup Recovery Manager..." and performs data recovery in the same way as with ordinary bootable media.
Limitations: cannot be organized on a dynamic disk; requires manual configuration of boot loaders, such as LILO and GRUB; requires re-activation of third-party loaders.
Archive
A file created as a result of an archiving operation (p. 196). The file includes a set of compressed files that a user selects for archiving. Archives can be stored in Acronis Cloud or local storage, such as an external hard drive or NAS, and they are accessible in read-only mode on a virtual Acronis Drive.
Archiving operation
An operation that compresses files that you select and moves them to Acronis Cloud or local storage, such as an external hard drive or NAS. The main purpose of the operation is to free up space on a hard drive by moving old or large files to different storage. After

completion, the files are deleted from their original locations and accessible in read-only mode on a virtual Acronis Drive.
B
Backup
1. The same as Backup operation (p. 197). 2. A set of backup versions created and
managed by using backup settings. A backup can contain multiple backup versions created using full (p. 198) and incremental (p. 198) backup methods. Backup versions belonging to the same backup are usually stored in the same location.
Backup operation
An operation that creates a copy of the data that exists on a machine's hard disk for the purpose of recovering or reverting the data to a specified date and time.
Backup settings
A set of rules configured by a user when creating a new backup. The rules control the backup process. Later you can edit the backup settings to change or optimize the backup process.
Backup version
The result of a single backup operation (p. 197). Physically, it is a file or a set of files that contains a copy of the backed up data as of a specific date and time. Backup version of files created by Acronis True Image 2021 have a .tibx extension. The TIBX files resulting from consolidation of backup versions are also called backup versions.
Backup version chain
Sequence of minimum two backup versions (p. 197) that consist of the first full backup version and the subsequent one or more incremental or differential backup versions. Backup version chain continues till the next full backup version (if any).
197

Bootable media
A physical media (CD, DVD, USB drive, or other media supported by a machine BIOS as a boot device) that contains standalone version of Acronis True Image 2021.
Bootable media is most often used to:  recover an operating system that cannot
start  access and back up the data that has
survived in a corrupted system  deploy an operating system on bare metal  create basic or dynamic volumes on bare
metal  back up sector-by-sector a disk that has an
unsupported file system
D
Data synchronization
Data synchronization is a process of keeping data identical in two or more synchronized folders. These folders may be located on the same computer or on different computers connected via a local network or via the Internet. When you create, copy, modify or delete a file or a subfolder in your sync folder, the same action is automatically done in the other sync folders. And vice versa - when something changes in the other sync folders, the same change is done in your folder.
Differential backup
1. A backup method used for saving data changes that occurred since the last full backup version (p. 198) within a backup.
2. A backup process that creates a differential backup version (p. 197).
Differential backup version
A differential backup version stores changes to the data against the latest full backup version (p. 198). You need access to the corresponding full backup version to recover the data from a differential backup version.

Disk backup (Image)
A backup (p. 197) that contains a sector-based copy of a disk or a partition in packaged form. Normally, only sectors that contain data are copied. Acronis True Image 2021 provides an option to take a raw image, that is, copy all the disk sectors, which enables imaging of unsupported file systems.
F
Full backup
1. A backup method that is used to save all the data selected to back up.
2. A backup process that creates a full backup version (p. 198).
Full backup version
A self-sufficient backup version (p. 197) containing all data chosen for backup. You do not need access to any other backup version to recover the data from a full backup version.
I
Image
The same as Disk backup (p. 197).
Incremental backup
1. A backup method used for saving data changes that occurred since the last backup version (p. 197) (of any type) within a backup.
2. A backup process that creates an incremental backup version (p. 198).
Incremental backup version
A backup version (p. 197) that stores changes to the data against the latest backup version. You need access to other backup versions from the same backup (p. 197) to restore data from an incremental backup version.

M
Mobile backup
A backup (p. 197) that contains files from a mobile device, such as a smartphone or tablet. The backup can be stored in Acronis Cloud or local storage on a computer.
N
Nonstop backup
Nonstop backup actually is a disk/partition or file backup that is created using the Acronis Nonstop Backup feature. This is a set of one full backup version (p. 198) and a sequence of incremental backup versions (p. 198) that are created at short intervals. It gives almost continuous protection of data, that is, it allows recovery of previous data state at any recovery point you need.
Nonstop protection
Nonstop protection - the process that the Nonstop Backup feature performs when it is turned on.
Notarization
A process of "remembering" a file state and defining this state as authentic. During notarization, Acronis Notary calculates a hash code based on hash codes of the files selected for notarization (p. 198), and then sends the hash code to a Blockchain-based database.
Notarized backup
A backup (p. 197) that contains files notarized with Acronis Notary.
Notarized file
A file that was notarized with Acronis Notary. A file becomes notarized after adding it to a notarized backup (p. 198) and sending its hash code to a Blockchain-based database.

O
Online backup
Online backup - a backup that is created using Acronis Online Backup. Online backups are stored in a special storage named Acronis Cloud, accessible over the Internet. The main advantage of an online backup is that all backups are stored on the remote location. It gives a guarantee that all backed up data will be safe independently of a user local storages. To begin to use Acronis Cloud a user should subscribe to the service.
R
Recovery
Recovery is a process of returning of a corrupted data to a previous normal state from a backup (p. 197).
S
Suspicious process
Acronis Active Protection (p. 196) uses behavioral heuristics and analyzes chains of actions done by a program (a process), which is then compared with the chain of events in a database of malicious behavior patterns. If the program acts similar to ransomware behavior and tries to modify a user's files, it is considered as suspicious.
Sync
1. The same as Data synchronization (p. 197).
2. Sync settings which were configured on the sync owner's computer. A created sync is managed using the corresponding sync box. Sync creation does not mean start of sync process. Other users may join a created sync.

V
Validation
An operation that checks whether you will be able to recover data from a particular backup version (p. 197).
When you select for validation...  a full backup version (p. 198) - the
program validates the full backup version only.  a differential backup version (p. 197) - the program validates the initial full backup version and the selected differential backup version.  an incremental backup version (p. 198) the program validates the initial full backup version, the selected incremental backup version, and the whole chain (if any) of backup versions to the selected incremental backup version. If the chain contains one or more differential backup versions, the program validates (in addition to the initial full backup version and the selected incremental backup version) only the most recent differential backup version in the chain and all subsequent incremental backup versions (if any) between the differential backup version and the selected incremental backup version.
Version of synced file
A state of a file which is located in a sync folder after each modification of this file. File versions may be stored on Acronis Cloud.
