So that’s all well in good what about Hyper-V? Hyper-V has support to VSS built in – so if your backup software is VSS enabled when you request a backup of a the physical (parent/host) server Hyper-V will forward those requests to each virtual machine (requires integration components and OS VSS support) then the guest will forward the request to any VSS aware application. In the end what you end up with is a back up of the parent/host will backup any virtual machines on that server and allow you to restore them individually or as a group.
-How to enable Windows Server Backup support for the Hyper-V VSS Writer Rob Hefner (Support Escalation Engineer for Hyper-V) wrote a great post on enabling support for the Hyper-V VSS writer for Windows Server Backup. This is a very helpful article! Make sure you have the “Windows Server Backup” feature enabled or you won’t be able to create the registry key…

Taylor,
I recently had the need to program backups of a certain Hyper-V configuration. The VM was running on a server abd we needed to make copies of it, from time to time, to another one. Yes, we should have used a SAN, but the client refused to.
So we checked Windows Server Backup but we came up with the surprise that it only backs up complete volumes, we found no way to tell it to copy a single folder. Does that option exist? Could you point us how?
Thanks in advance.
"After doing a backup using Windows Server Backup – I can now restore a specific virtual machine… I am showing the backup contains the ID’s of all the VM’s for the Hyper-V “application”… "
How are you accomplishing that?
==========================================================When the backup is requested by the backup application it calls our VSS listner that knows about all virtual machines and performs that backup.

If you use Windows Server Backup or any other VSS aware backup utility you should make sure and pick
Tony Soper: The matrix of considerations for backup and DR for Hyper-V is not simple, for example there are several methods to backup running VMs such as Windows Server Backup, DPM, diskshadow.exe, as well as non-Microsoft solutions such as Symantec Backup
Hi Taylor,
Very useful thanks. However, we've found the backup files are prohibitively large: too big to back up onto a remote computer. There are one or two programs out there that'll combine VSS with RSync & provide differential backups. We use Hyperoo (www.hyperoo.net) to back up our virtual machine onto a remote machine every hour - handy if you need to restore to a specific point in time!

Any idea how we can do snapshot backup on hyper-v cluster?
Sandheep - Hyperoo (www.hyperoo.net) fully supports snapshots of Hyper-V environments running on Microsoft Cluster Shared Volumes.
It's free to trial: give it a whirl :)
