Actions with archives on tapes in a library
The following are common functions for archive data management for a backup archive selected in the Centralized vaults view of the console, when the current vault is a tape library: Validate, Delete, Delete all archives. Deletion in the storage node database is performed without access to tapes. A backup archive deleted from a tape library vault can be restored after the deletion by the Rescan operation, which is performed for all the tapes keeping the archive’s data.
The Rescan operation for a tape, where a backup was deleted from, can recover the backup, as it recreates information on the content of the backup in the storage node database.
If all the backups are deleted from a tape, it is considered as free. So the deleted backups will be irrevocably lost after the first writing to the tape.
