Delete Deduplication Backup Sessions

CA 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. CA ARCserve Backup lets you delete deduplication backup sessions so that you can free disk space and remove obsolete and redundant session information from the CA ARCserve Backup database.

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

• If the deleted sessions are referenced by other deduplication backup sessions, the information about the sessions is removed immediately from the CA ARCserve Backup database. However, CA ARCserve Backup cannot reclaim the disk space until the deleted sessions are not referenced by other deduplication backup sessions.
• If the deleted sessions are not referenced by other deduplication backup sessions, the information about the sessions is removed immediately from the CA ARCserve Backup database. To reclaim the disk space immediately, you must stop and restart the Tape Engine.

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