I think you're talking about the failover/failback scenario: The source and target can be configured so that after failover transition, the former target becomes the new source; and the former source becomes the new target of the new source automatically. There is no need to create another target to restore the original one source, one target configuration. To failback to the original server A for the source, another failover transition will be needed. The failover transition is basically a role switch without breaking replication. This can be done with just two databases. Replication set will allow the second target transition together with the source and the first target. So after failover, you'll still have one source and two targets without re-bases. Dapeng
