You can restore SnapManager backup copies that were created on other Exchange servers to either the same Storage Group or the Recovery Storage Group. By default, SnapManager restores the backup sets to the Exchange server on which the restore operation is initiated.
To restore the backup copies from a different Exchange server to the Exchange server where the restore operation is initiated, you must first remap the source LUNs to the Exchange server by using either the same drive letters, or volume mountpoints (both drive letters and volume mountpoints) that were assigned for the original Exchange server.
To use the restored backup set created on another Exchange server for a particular Storage Group, all database LUNs, transaction log LUNs, and SnapInfo LUNs must be remapped to the destination.
