To perform an image-based backup of a virtual machine that contains vCenter Server, a vCenter Server Appliance, or a Platform Services Controller, you must first deploy and configure vSphere Data Protection and complete basic backup tasks.
The topology of your
vCenter Server environment may vary and consist of many
vCenter Server and
Platform Services Controller instances. You must always perform the backup of all
vCenter Server and
Platform Services Controller instances simultaneously.
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.
