Catalog Database Pruning

Whenever you use Arcserve Backup to back up information and data, the amount of description information (catalog files and index files) stored in the catalog database folder increases. Without any controls, in time the size of the catalog database folder would increase, eventually occupying the entire backup disk, and resulting in backup errors due to insufficient free disk space.

To resolve this problem, Arcserve Backup allows you to specify a catalog database pruning threshold. The pruning threshold (or Minimum disk free space threshold) setting is accessible from the Configuration dialog of the Server Admin Manager. The selectable range of this threshold is from 1% to 99%, with the default value set to 10%, and is based on the percentage value of the detected free disk space.

Note: Arcserve Backup periodically checks the free disk space percentage on the volume where the catalog database folder is located. If the detected free space is lower than the specified percentage, a warning message will be sent to the activity log and it would automatically begin to delete catalog database files (minimum of 7 days old and starting with the oldest first) from the disk until the detected free space percentage is greater than the threshold setting.
