Maximum snapshot limit retention type for SLP operations
The Maximum snapshot limit determines the maximum number of snapshots that can be stored for a particular policy and client pair.
When the maximum is reached, the next snapshot causes the oldest job-complete snapshot to be deleted. A snapshot job is considered to be complete once all of its configured dependent copies are complete. (Dependent copies are created as a result of Backup From Snapshot, Index From Snapshot, or Replication operations.) The practice is referred to as rotation. This retention type applies only to snapshots, and not to backups.
For example, Policy P1 contains two clients: C1 and C2. After the policy runs four times, it creates four snapshot images for C1 and four images for C2. If the Maximum snapshot limit is set to four, when the policy runs for the fifth time, NetBackup deletes the first snapshot that was created for both C1 and C2 to accommodate the fifth snapshot.
The Maximum snapshots parameter in the Perform snapshot backups Options dialog determines the maximum number of snapshots. To access the dialog box, click under Snapshot Client section in the backup policy.
