Delete Deduplication Backup Sessions

Arcserve Backup deletes deduplication backup sessions from deduplication devices based on the purge policy (retention period) that was specified when you submitted the backup job. However, deduplication backup sessions can become obsolete or redundant before the specified retention period expires. Arcserve Backup lets you delete deduplication backup sessions so that you can free disk space and remove obsolete and redundant session information from the Arcserve Backup database.

When you delete deduplication backup sessions, Arcserve Backup behaves as follows:

• When the deleted sessions are referenced by other deduplication backup sessions, the information about the sessions is removed immediately from the Arcserve Backup database. However, Arcserve Backup cannot reclaim the disk space until the deleted sessions are not referenced by other deduplication backup sessions.
• When the deleted sessions are not referenced by other deduplication backup sessions, the information about the sessions is removed from the Arcserve database and the disk space is reclaimed immediately.

Important! The deleting of deduplication backup sessions is an irreversible process. You cannot recover deleted deduplication backup sessions.

Follow these steps:

1. From the Quick Start menu on the Arcserve Backup Home Page, click Restore.
2. Click the Source tab in the Restore Manager.

   From the drop-down menu, select Restore by Session.

   The Sessions directory tree appears.

3. Expand Sessions to view the devices containing backup sessions.
4. Browse to the deduplication device containing the sessions that you want to delete.

   Expand the deduplication device to display the deduplication backup sessions stored on the device.

5. Locate and select the sessions that you want to delete.

   Right-click the sessions that you want to delete and click Delete Selected Sessions on the pop-up menu.

   When prompted, click Yes to delete the selected sessions.

   The sessions are deleted.
