You can use Thin Image Advanced to back up TrueCopy and Universal Replicator volumes on the remote sites in a 3DC multitarget configuration.
The following figure shows how to back up the volumes.
- Pair 1 is a TrueCopy pair.
- Pair 2 is a Universal Replicator pair.
- Pair 3 is a Universal Replicator pair for delta resync.
- Pairs 4, 5, and 6 are Thin Image Advanced pairs.
You must create 3DC multitarget and delta resync pairs (pairs 1, 2, and 3) before creating pairs 5 and 6, but pair 4 can be created at any time.
