Dell PowerStore Protecting Your Data

A resource is added to the Resources table after a remote backup session that was created for the resource triggers the creation of a remote snapshot.

If a volume or a volume group that has associated remote snapshots is deleted from PowerStore, the remote snapshots are not impacted. The deleted resource remains listed on the Resources table until all its associated remote snapshots are expired. To see whether a resource is deleted, add the Source Deleted column to the Resources table, using the Show/Hide Table Columns option.

From the Resources tab, you can perform the following actions:

• Manage Snapshots—Selecting a resource from the list and clicking Manage Snapshots, displays all the remote snapshots that are created for this resource:
  • The expiration time of both automatic and manually created snapshots is based on the retention time that was configured in the remote backup rule.
  • The expiration time of a remote snapshot cannot be changed. Changing the retention period in a remote backup rule does not affect existing snapshots.
  • For automatically generated snapshots, a remote snapshot name includes the name of the remote backup rule that created it.
  • Selecting a snapshot from the list and clicking Retrieve creates a retrieve session for this snapshot. See Retrieve a remote snapshot to the same PowerStore cluster for details.
  • Selecting one or more snapshots and clicking Delete deletes the snapshots.
  NOTE:You can also see the remote snapshots for a resource and perform related actions by clicking the resource and then selecting the Remote Snapshots tab.
• Instant Access—Selecting a resource from the list and clicking Instant Access initiates the process for enabling instant access for the selected remote snapshot. For details, see Create an instant access session.
• Discover Remote Snapshots—Use this option when you want to retrieve a remote snapshot of a resource on a different PowerStore cluster. For details, see Retrieve a remote snapshot to a different cluster.
