How SnapMirror works with the dump command

You can use the dump command to back up data from a SnapMirror destination volume. The dump command picks the most recent Snapshot copy and copies that to tape.

You can back up any Snapshot copy displayed by the snap list command on the destination. You can also create a Snapshot copy on the source volume, copy the Snapshot copy to the destination, and use the dump command to back up this Snapshot copy from the destination to tape.
