Hyper-V guest Backup in VSS
Hi Puntos,
Did you restart the Hyper-V Volume Shadow Copy Requestor (vmicvss) after the turn off/on off Backup?
You can check the Application eventlog for the Task Category ShadowCopy events 2001, 2003 and 2006, or maybe you see errors there?
A test to be sure if VSS is the one who stops your backup from working is the following:
- Stop the Hyper-V Volume Shadow Copy Requestor (vmicvss) service on the VM
- Create a backup
Be aware that this procedure will pause your VM during the backup! So don’t do this in production time!
Hope this helps you further, if VSS is working I would suggest to consult with your backup vendor again.
Regard,
Erwin
Hi there again,
The backup still freeze when i shut down the vmicvss.. In the log of the vmhost where the guest is. I got following error (4000) Failed to connect to virtual machine 'bkbupdmz01' because there is no mutually supported protocol for VM: (Virtual machine ID 223A61EB-75E9-4494-AE75-36978840CC40). Framework version: Negotiated (0.0) - Expected (3.0); Message version: Negotiated (0.0) - Expected (4.0)."
Is there anything that need to be open on the network for this to be working?

I have a similar problem with Snapshot backups but with Netapp software.
Windows Server 2012 R2 Hyper-V cluster with SMB 3.0 connection for storing VMs on Netapp SAN. All my VMs with WS2008R2, WS2012, WS2012R2 works great with the snapshots but with WS2016 there is a freeze for a short period so applications like NAV and TFS become unresponsive. To avoid problems I have had to move the snapshots to be taken outside of working hours but then the whole point of having snapshots is lost...
Lets hope that it is in the Integration tools and that it will be solved soon.
Hi Pontus,
Looks like a problem with the Integration tools, is the VM using the latest updates?
Don't no how to reinstall them using Server 2016, this is changed from the Server 2012 R2 procedure.
