Backup failures / corrupt files should be automatically removed
With the new automated backup system. If a backup should fail for whatever reason, it should delete (or move someone temporarily) the files it created before trying again. I recently had an instance where a file was corrupt and every time it tried to generate a backup it would fail midway into creating the archive. This was another backup file was was incomplete (not sure how that happened). I had 5 consecutive backups get created with large chunks of missing files and no way of knowing until I opened one of the generated backups.
If the backup files, an email notification should be sent to the administrator and it should move (or delete?) the broken files before starting again.
