Virtual machine maintenance after a restore

Note the following about restoring a virtual machine in a cluster:

Virtual machines are always restored to a state of non-high availability. To return the virtual machine to high availability, use the Microsoft Failover Cluster Manager and the High Availability Wizard. For instructions, refer to the following Microsoft document:
Hyper-V: Using Hyper-V and Failover Clustering
If the existing virtual machine has a status of high availability and the restore overwrites the virtual machine, note the following:
- The existing virtual machine's cluster resources are removed during the restore.
  See Removal of cluster resources during restore.
- The virtual machine's cluster group is not removed during restore. When two or more virtual machines are created on the same cluster disks, the cluster software places their resources in the same virtual machine group. Since another virtual machine may share that group, NetBackup does not delete the group.
  Removal of the cluster group must be done manually. Refer to Microsoft documentation for instructions.
