After you back up a VM that contains vCenter Server, vCenter Server Appliance, or Platform Services Controller, you can restore the backup images to the original location or a new location.
You can restore VMs to the original location by either overwriting the backed up VM or by creating a new VM that contains the restored vCenter Server, vCenter Server Appliance, or Platform Services Controller on the same ESXi host. You can also restore the VM on a new ESXi host.
You can restore a VM on the ESXi host that is running the vSphere Data Protection Appliance. The direct‐to‐host emergency restore operation lets you restore a VM when vCenter Server becomes unavailable or when the user cannot access the vSphere Data Protection user interface by using the vSphere Web Client.
