Volume backup with Thin Image and Universal Replicator in a 3DC cascade configuration workflow (VSP G1000 only)

You can use Thin Image to back up Universal Replicator volumes on the remote sites in a 3DC cascade configuration.

The following figure shows how to back up the volumes.

• Pairs 1 and 2 are Universal Replicator pairs.

• Pair 3 is a Universal Replicator pair for delta resync.

• Pairs 4, 5, and 6 are Thin Image pairs.

You must create pairs 1 and 2 before creating pairs 5 and 6, but pair 4 can be created at any time.
