Volume backup with Thin Image, TrueCopy, and Universal Replicator in a 3DC multitarget configuration workflow

You can use Thin Image 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 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.

(VSP G200, G400, G600, G800 only) You cannot share 3DC volumes that use two mirrors with Thin Image.
