Your environment might contain multiple vCenter Server instances registered with different external Platform Services Controller instances that replicate their data. You can use vSphere Data Protection to back up and restore the whole environment so that if a Platform Services Controller fails, you can restore the failed Platform Services Controller.

Important: You can back up and restore only virtual machines that contain vCenter Server, vCenter Server Appliance, and Platform Services Controller. You cannot back up and restore physical machines that are running vCenter Server by using vSphere Data Protection.
