Once a backup label has been expired, it will not be possible to verify or restore data

from this backup using the Backup Administrator application. However, you will still

be able to reinstall a system from a System Backup even if it has been expired. If a

backup has been expired or the label history has been inadvertently removed from

the system, it is still possible to rebuild this information. Refer to Rebuild (unexpire)

a Backup Label for details.

Very important note: If you expire a backup that was written to disk, rather than tape,

the actual disk backup will be removed from the backup server. You are given ample

warning before the backup is removed, and once it has been removed it will no

longer be possible to access that data.

Manually Expiring a Backup

To manually expire a backup, first perform any one of the various methods to view the backup label . Then

select the Expire/Remove button at the bottom of the screen.

Automatic Expiration of Backups

The Backup Retention Policies determines if and when an old backup may be overwritten by a new backup.

Any time an old backup is overwritten by a new one, the previous backup label must be expired as the data

the label points to will no longer exist.

For tape backups, if the Tape Overwrite/Retention Policy has been set to allow current labels to be

overwritten by new backup jobs, the backup being overwritten will be automatically expired, allowing the

tape to be overwritten by a new backup.

For disk image backups, expiring the backup label also means removing the actual backup image files from

the disk on the server. The Disk Backup Retention Policy determines when a prior backup can be

automatically expired.

In either case, the retention policy only applies when writing a new backup using the

same backup job.

When this occurs, the policy may allow:

1. No backup to be expired, removed or overwritten without manual expiration.

2. Any backup to be automatically expired and overwritten

3. Expiration of backups that are older than a certain number of days

4. Expiration of a backup only if there are a minimum number of un-expired backups of the

same job

remaining.
