For additional security, you can back up the Active node in the vCenter HA cluster. You can then restore the node in case of catastrophic failure.
Remove the cluster configuration before you restore the Active node. Results are unpredictable if you restore the Active node and the Passive node is still running or other cluster configuration is still in place.
Verify the interoperability of vCenter HA and the backup and restore solution. One solution is vCenter Server Appliance file-based restore.
- Back up the Active node.
Do not back up the Passive node and Witness node.
- Before you restore the cluster, power off and delete all vCenter HA nodes.
- Restore the Active node.
The Active node is restored as a standalone vCenter Server Appliance.
- Reconfigure the vCenter HA.
