You can run a failback recovery plan to restore a protected site.
Once you start a failback plan, do not make any inventory changes on the protected site until the failback completes. You cannot edit a recovery plan once the plan has been started.
Importantly, do not power on any VMs in a plan during a failback operation. Wait until the failback completes, and then you can power on VMs in the plan.
If you need to make any protected site vCenter inventory changes, such as renaming a data center, or moving VMs to different folders or resource pools, do so before you initiate a recovery plan for failback.
Also, make sure that the plan’s compliance check succeeds before you run the plan. Running a failover when the plan compliance check is not all green will likely result in a failback failure.
Note: If you perform a failback of a VM from a high-frequency snapshot, and it fails, all retried failbacks for this VM will require a full restore (which can take longer than ususal).
