  1. You create a backup task, and under Where to back up you specify a managed vault;
  2. After the backup task runs one or several times, you browse to the managed vault and delete the archive there;
  3. After deleting the archive, the backup task to the managed vault fails to run. The error message is similar to the following one:

    UNKNOWN_ARCHIVE_GUID; Archive with such guid does not exist


Archive is a container for backups and is created during the backup policy creation, independently of whether there is a backup in the managed vault or not.

The failure occurs since there is no archive container present in the managed vault which corresponds to the existing backup task settings and this archive container is not re-created by an already existing task. The archive container is created only when you actually set up the task itself.


(!) This has been fixed and the fix is available in the latest released build of the product. See Installation of the latest update of an Acronis product.
