Before starting a backup of a virtual machine, verify that the NetBackup master server and media server can communicate with the Hyper-V server. Add the name of the NetBackup master server to the server list on the NetBackup client and (optional) alternate client.
On a virtual machine, Windows shadow storage for a volume (such as C:) does not have to be configured on the same volume. For instance, shadow storage for the C:\ volume can be configured on D:\. If the Hyper-V server is Windows 2008 R1 and shadow storage for a volume is not configured on the same volume, note: Windows hotfix KB959962 must be installed to perform an online backup of the virtual machine. In this case, if the Hyper-V server is 2008 R1 and the hotfix has not been applied, the backup is performed offline.
Windows 2008 R2 contains all required hotfixes.
Windows shadow storage is required whenever the Windows Volume Shadow Copy Service (VSS) creates point-in-time snapshots.
