When virtual machines are configured for high availability, they are moved to a new node in the backup selection list. Clustered virtual machines appear under the name of the cluster, in the Highly Available Hyper-V Machines node. Non-clustered virtual machines remain in the Microsoft Hyper-V node. When you make a backup selection, Backup Exec checks for highly available virtual machines. If highly available virtual machines are discovered, Backup Exec reminds you to select those virtual machines for backup.
The restore selection list is similar to the backup selection list. Clustered virtual machines appear under the name of the cluster. Non-clustered virtual machines appear under the Microsoft Hyper-V node. You can restore a highly available virtual machine in the same way you restore any other virtual machine. The virtual machine maintains its high availability. However, if you redirect the restore to another Hyper-V host, then the virtual machine is no longer highly available when the restore job completes. You must reconfigure the virtual machine to be highly available.
