As a workaround, validate the backup manually

There is no information in the log on what backup archive was validated

The location of your backup archive has changed or is unavailable

Acronis Backup & Recovery 10 does not support E-mail notifications for validation tasks

How to validate backups automatically and manually

The article describes an issue related to failure of credentials check when enabling Exchange-aware backup option in the backup wizard of Acronis vmProtect

Make sure the backup slice you are trying to validate is in the same folder with the rest of the chain. If it is, this slice is probably corrupted. Please recreate it

The backup is on an external disk which is unavailable at the time of the validation

This is a known issue. Do not run the validation task of a backup stored online if this may potentially interfere with other Acronis Backup & Recovery 10 tasks

Do not use special symbols in archive names, except pre-set templates in the product.

The operation fails because the archive meta information is damaged or missing. Run vault validation to fix the issue

How to check if the installation file has been downloaded correctly


You created multiple full backups in .tibx format. Then some of the backups were deleted or moved to a different location.

When you try to validate the backup using Validate all versions option, validation fails.


Specifics of product implementation. If some of the backups were moved or deleted outside Acronis True Image interface, then the integrated backup structure will be broken, resulting in the inability to validate the backup, as some parts of the backup archive are missing.

  1. You create a backup using Version 12 format.
  2. An operation with archive (e.g. applying retention rules) fails with the error message

    Failed to lock the file


  1. You installed Update 4 of Acronis Cyber Backup 12.5 (Build 12730)
  2. After update, deleted off-host data processing plans (replication, validation, cleanup) start running on schedule. It is not possible to delete these plans because they are not shown in Management Console.


Issue in the product.


This issue is fixed in Build 12860 and later, please update the product to the latest build.
