PowerProtect Data Manager 19.17 Storage Array User Guide

Replication triggers

PowerProtect Data Manager orchestrates protection policy replication objectives independently of the primary backup.

The default replication trigger is a schedule window that you define by setting a recurrence period plus start and end times. Replication occurs during the defined window. For example, every day between 8 PM. and 12 AM.

You can also trigger replication immediately after the completion of the associated primary backup, whether scheduled or manual. At the start of the primary backup, PowerProtect Data Manager generates an associated replication job that remains queued until the end of the protection job. If the backup fails or completes with exception, the associated replication job is skipped. Restarting the protection job queues the associated replication job again.

When you add a replication objective to a policy, you can specify either a scheduled replication or replication after backup completion. Using a schedule can help you manage network traffic by replicating during off-peak hours. However, for larger backup sets, the primary backup may not finish before the start of the replication schedule, which creates a replication backlog. Replication after backup completion prevents a replication backlog.

To prevent data loss, the replication after backup completion trigger replicates new backups from the primary objective and any outstanding backups that have not yet replicated.
