You can install or deploy a Platform Services Controller and register several vCenter Server instances with the same Platform Services Controller. You can use vSphere Data Protection to restore the whole environment, so that if any of the vCenter Server instances fails, you can restore the failed vCenter Server instance.
You must restore each failed vCenter Server.
Back up the virtual machines on which the vCenter Server instances reside.
What to do next
Power on the restored virtual machine that contains the restored vCenter Server instance.
