An archive consists of slices, which in turn may consist of volumes

You can import an archive to a managed vault only through command line

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

When you try to recover your backup and upon pressing "Recover" a warning appears

The issue has been fixed, please upgrade to Acronis Backup 11.5 (Acronis Backup & Recovery 11.5). This an issue with filtering information when browsing. On restore, the correct files are recovered


  1. You save backups to an unmanaged location using Version 12 archive format 
  2. Two or more backup archives have the same "Date modified" value


Acronis Backup 11.7 had Simplified naming of backup files

Acronis Cyber Backup 12.5 currently does not support simplified naming.

Each backup plan creates one or more files in the backup location, depending on which backup scheme and which backup format are used. The following table lists the files that can be created per machine or mailbox.


Backup or a different operation (replication, recovery, etc) fails with the following error:

The archive is invalid or its type is unsupported
