Replication
Performing a Failback for a Partition
Perform a failback of a VTL partition if a source system that was previously unavailable
becomes available again. When you failback a partition, you select a received snapshot.
The ETERNUS CS800 copies the snapshot from the target system back to the source
system. You can then perform a recover operation to recreate the partition on the source
system just as it was at the point in time when the snapshot was saved.

2. (Optional) In the Failback Destination System box, type the hostname or IP address
of a new destination system to failback the partition to. (The default destination is the
original source system.)
