Backup Exec is supposed to clear (prune) expired data on a regular basis but the process can mess up more often than not.Backup Exec will NOT delete old data sets, even if they are expired, if more recent full backups have not been successful nor will it let you overwrite those media sets.To force the clean-up of old, expired data you need to do the following (all of this is predicated on Backup Exec 2012, older versions may operate differently).The end result is you can run out of space on your media even though your jobs are set to “overwrite” older media.The biggest cause of this kind of problem is inconsistent results with full backups.I have read the manual but honestly I have not understood.I am sorry for my basic question but it seems that what I have written is not enough for serverfault..This will tell BUE what is in the drive and what backup media files exist.Then you'd run a catalog against those media files in order to see what actually exists WITHIN those backup media files to be able to restore. I'm sure you can simply look in the docs..here's my definition...Catalog = a list of the files/folders/dates/etc backed up WITHIN a backup file that BUE created. If the catalog has expired in the BUE database, then you'll need to run a catalog on the backup media in order to restore files from them. Inventory = when run against a Library or Backup-to-Disk-Folder will inventory that location looking for backup files and listing them along with what media set they are in (and therefore when/if they are overwriteable, appendable, etc.).
