Backup Hyper-V VM Using Windows Server Backup in Windows Developer Preview

If you recall on Windows Backup in Windows Server 2008 R2, you need to backup the entire volume. Same goes when you restore. Therefore it is not a good tool to backup Virtual Machine.

However, during my testing on Windows 8 (Windows Developer Preview), i have realize that you can now backup individual Virtual Machine by using Windows Backup.

Here is the snapshot when selecting Virtual machine:-

Description about:-
Host component  - backup Azman, Resource pool configuration
Child Partition - Online backup when the VM is running
Saved State - Slight downtime when backup guest VM which does not have VSS provider. Example:- Some Linux distro, Windows Server 2000 or NT. The VM will be Saved State when create a copy of backup. That's why a slight downtime when backup these VMs.
