Volume backup with Thin Image in a 3DC multi-target configuration workflow
You can use HTI to back up TC and UR volumes on the remote sites in a 3DC multi-target configuration.
Pair 1 is a TC pair.
Pair 2 is an UR pair.
Pair 3 is an UR pair for delta resync.
Pairs 4, 5, and 6 are HTI pairs.
You must create 3DC multi-target and delta resync pairs (pairs 1, 2, and 3) before creating pairs 5 and 6, but not before creating pair 4.
You cannot share 3DC volumes that use two mirrors with HTI.
