When disaster strikes on a production data center, the Takeover operation is invoked to start the resiliency groups on the recovery data center.
Since the production data center is not working the data replication between the two sites does not happen. Later when the production site is up and running you need to prepare the site for next failover or migrate operation. This includes cleaning up any residue and resuming the replication from recovery to production site.
Use the Resync operation on the Resiliency Platform console to automate these steps for the required resiliency groups. This operation cleans up the residue which includes stopping applications and virtual machines, deregistering virtual machines, unmounting file systems, datastores, etc.
Resync operation can be performed only if the last Takeover operation was successfully completed.
