To expire a backup image means to force the retention period to expire. When the retention period expires, NetBackup deletes information about the backup. The files in the backups are unavailable for restores without first re-importing.
To expire a backup image
In the NetBackup Administration Console, expand NetBackup Management > Catalog.
Set up the search criteria for the image you want to expire, then click Search Now.
Select the image you want to expire and select Actions > Expire.
A message appears that announces that once the backups are expired, they cannot be used for restores. Select Yes to begin to expire the images.
