Location: Options > Advanced > Validation

This option is not available for the backups that use Acronis Cloud as a backup destination.

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.
