Reversing failover
After a live failover has been performed, you can reverse the protection. This allows you to replicate
target data back to the source. Select a protection that has already failed over, then click the
Reverse protection button to start the protection in the reverse direction.
The job will start synchronization in the reverse direction. The job name and the log file name will
change accordingly. When the restore completes, the job will be running in the opposite direction
(that is, if the job had originally been running from server
Indy to server Jersey, it will now be
running from server
Jersey to server Indy).
After the job completes synchronization back to the original source host, failback can be performed
by clicking the Failover button.
