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