Error 2012/08/28 11:31:57 602 Jobs BACKUP-MASTER Fatal error: Backup failed
-
Cause
This was due to the volume having filled up with snapshots, the reason for the snapshots filling up the volume was that under the backup Options of the Job was not using the
"Delete Snapshot on Exit" option, this would delete the snapshots generated by the Plug-in for SM2T after the backup completes.
-
Resolution
When the option "Delete Snapshot on Exit" has not been set, the user would need to delete the snapshot manualy to ensure that the volume does not fill up.
