Dell PowerStore Protecting Your Data

You may want to retrieve a remote snapshot for restoring the source resource or creating a thin clone.

Retrieve a remote snapshot to the same PowerStore cluster:

• If the source volume or volume group of the retrieved backup still exists in the system, a local snapshot is created on the PowerStore cluster. If possible, the retrieval is incremental.
• If the source volume or volume group of the retrieved backup no longer exists in the system, both a new volume and a local snapshot are created, and the new volume is restored with the snapshot data.

Retrieve a remote snapshot to a different PowerStore cluster:

• Since the source volume never existed on that cluster, both a new volume and a local snapshot are created. The new volume is restored with the snapshot data.

For each retrieve operation, a retrieve session is created. The initial status of the session is Prepare. Once the session starts copying the snapshot, the status changes to In-Progress and after the snapshot is copied, the state changes to Completed.

You can view and monitor the retrieve sessions progress in the Retrieve Sessions tab (Protection > Remote Backup). You can also perform the following actions:

• Delete—Use this option to delete a retrieve session in a Completed status.
• Cancel—Use this option to cancel a retrieve session in In Progress status.
  NOTE:When the session status is In Progress, other sessions may be queued before it. When you click Cancel, the session state changes to Canceling, but the session is cancelled only when it reaches the top of the queue and becomes active.

After a backup is retrieved, it functions as any local snapshot. You can use a retrieved backup to restore a primary volume or to create a clone. The retrieved snapshot is set to No Automatic Deletion. You can change that setting by configuring a retention period. You can also modify it to a secure snapshot.
