After a Replication Backup of a Share Disk is completed on a remote NAS, the backup is available for future
recovery. During the recovery, the remote replicated Share Disk is mounted in the same position as the original
local Share Disk. When the recovery is completed, the recovered original Share Disk automatically goes back into
the normal position and the replication backup Share Disk reverts to backup status.
Keep in mind the following points for Replication Recovery:
