    I think my deduplication store isnt pruning the old jobs properly.  Is there an easy way that I can determine what the problem is and or fix this problem so that my storage is not filled up over time?

     

    Thanks ahead of time for the input!

    There was a bug many service packs ago where the DDB backups wouldn't get pruned automatically. Usually, it should only keep the last backup but from time to time, it would stop deleting old jobs and your DDB mount path would fill up.

    The SIDB's current backup will only be in the most recent folder (you can check by comparing the size of your SIDB and the size of your backup) so it is safe to delete older folders in your /cvstorage/cv_lv_01/SP_DDP_HQ_VM/CV_SIDB/2/94/BACKUP/94 folder. This should free up a lot of space.

    If you're using SP4 or later, I'd suggest moving away from those backups and using the new way which is through the filesystem agent. You can check the following link in the BOL for more info:

    http://documentation.commvault.com/commvault/release_9_0_0/books_online_1/english_us/features/dedup_disk/advanced.htm#Deduplication_Store_Database

    If you are pre SP4 and can't upgrade, there's a registry key to move the DDB backup to another mount path so that at least if it fills up, it won't impact your live DDB. I'll have to search to find what the key was... let me know if you need it or if you're just going to move to the new DDB backup strategy.
