Dell PowerStore Protecting Your Data

Remote backup

Remote backup enables you to back up volumes and volume groups directly from PowerStore to a PowerProtect DD.

PowerStore supports backing up to a physical PowerProtect appliance or to a PowerProtect DD Virtual Edition (DDVE).

A remote backup creates a snapshot of a volume or a volume group on the PowerProtect system. The created snapshots are crash-consistent and there is no application integration.

Once they are on the PowerProtect DD, backups can be retrieved to an existing or new PowerStore cluster. You can also browse the contents of a backup on the DD, using instant access, and gain quick temporary access to the backed-up snapshots without retrieving them to the PowerStore cluster.

When a resource is backed-up for the first time, a full copy is created. Following backups are incremental - Only the changes from the last backup are copied to improve efficiency.

When you assign a protection policy that includes a remote backup rule to a volume or volume group, a remote backup session is created. Only one remote backup session can be created per resource. Remote backup sessions are displayed in the Backup Sessions tab of the Remote Backup page.

Remote backup is initiated from PowerStore. The remote backup workflow is outlined in Remote backup basic workflow.

A remote session tracks each of the operations (backup, retrieve, and instant access). You can monitor the session progress and perform actions from the remote sessions pages.
