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.
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. 87) 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.
