Our setup is pretty basic as follows....
- Veeam running on a physical 2008R2 box backing up to local storage
 
- No separate backup proxy servers
 
- One backup job to backup all 24 VMs running on a 2008R2 Hyper-V cluster
 
- VMs are a mix of Svr 2008R2 and 2012
 
Guest processing skipped (check guest OS VSS state and integration components version)
Looking in the Application Event Log on the affected VMs I see the following error...
Code: Select all
Log Name:      Application
Source:        vmicvss
Date:          20/08/2013 21:14:39
Event ID:      13

Description:
Windows cannot perform an online backup of this system because scoped snapshots are enabled. To resolve this, disable scoped snapshots by creating the following registry value on this computer:
 	PATH: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\SystemRestore\
 	DWORD: ScopeSnapshots
 	Value: 0
 Incorrectly editing the registry may severely damage your system. Before making changes to the registry, you should back up any valued data on the computer.

</Event>I have today added the registry key given in the above error to one of my 2012 VMs and will see what change this brings when the backup job next runs.
