How to Specify Tape Catalog Retention
Updated: April 21, 2010
Applies To: System Center Data Protection Manager 2010
DPM maintains metadata for each tape in a database, referred to as the tape catalog. You can manage the retention settings for the tape catalog to determine when the catalog is pruned, which consists of removing entries from the catalog.
DPM will automatically prune the catalog when the retention range for the protection group expires. You can direct DPM to prune the catalog for all protection groups sooner to reduce the size of the database. Because the duration of the catalog retention impacts the size of the DPM database, you can use the Tape Catalog Retention dialog box to alert you when the DPM database reaches a specific size.
To specify tape catalog retention
In DPM Administrator Console, click Protection in the navigation bar.
Select a protection group.
In the Actions pane, click Specify tape catalog retention.
To prune the catalog when the retention range expires, select Prune catalog when protection group retention range expires.
To prune the catalog for a specific tape duration, select Prune catalog for tapes older than, and then select the tape duration that you want to use.
Note You cannot retain catalog data longer than the retention range for the protection group.
If you want DPM to alert you when the DPM database reaches a specific size, in the DPM Database section, select Alert me when the DPM database size reaches, and then specify the size of the database.
