 = Restoring a single VM from a backup of multiple VMs
 
+[role="_abstract"]
 If you have a backup containing multiple virtual machines (VMs), and you want to restore only one VM, you can use the `LabelSelectors` section in the `Restore` CR to select the VM to restore. To ensure that the persistent volume claim (PVC) attached to the VM is correctly restored, and the restored VM is not stuck in a `Provisioning` status, use both the `app: <vm_name>` and the `kubevirt.io/created-by` labels. To match the `kubevirt.io/created-by` label, use the UID of `DataVolume` of the VM.

 = Restoring a single VM
 
+[role="_abstract"]
 After you have backed up a single virtual machine (VM) by using the label selector in the `Backup` custom resource (CR), you can create a `Restore` CR and point it to the backup. This restore operation restores a single VM.

 [WARNING]
 ====
 If you run a backup of a Microsoft Windows virtual machine (VM) immediately after the VM reboots, the backup might fail with a `PartiallyFailed` error. This is because, immediately after a VM boots, the Microsoft Windows Volume Shadow Copy Service (VSS) and Guest Agent (GA) service are not ready. The VSS and GA service being unready causes the backup to fail. In such a case, retry the backup a few minutes after the VM boots.
