Carlos, thank you for your reply. When I install update KB2966407 system reports that the update is already present. Apparently, the solution does not work.
Title HyperV backup fails after uplying Windows Server 2012 R2 Update KB2919355
Impact
HyperV 2012 R2 backups fail after applying the Windows update KB2919355
Issue
Backups fail with the following error as seen in the NMM.raw file:
80777 4/15/2014 3:14:41 PM 5 0 0 9992 10308 0 node1.myorg.local nsrsnap_vss_save NSR critical ERROR : Failed to verify file path (C:\ClusterStorage\volume1\sqlsrv\Snapshots\) for the writer "Microsoft Hyper-V VSS Writer". Files(CF106A5A-72FB-44C3-BFC7-3E7624B9C836.xml) under the path can not be backed up. Possible reason could be a missing file or folder in the specified path.
NMM 3.0 Sp1 HyperV 2012 R2 with VMs on CSV volumes
Cause
Backups fail after installing Microsoft update KB2919355.
Change
Backups started failing after the Windows Server 2012 R2 Update KB2919355 was applied
Resolution Microsoft has resolved this issue and a hotfix KB2966407 is available through Microsoft support .
Microsoft will release this fix as part of the June Roll up. However customers can access this hotfix immediately by opening up a Microsoft support call.
I have this same problem and seems it happens only with some Hyper-V instances. There is kind of workaround for this one: do not choose problematic Hyper-V instance for backups. So you have to manually choose hyper-v instances that you want to backup, problem is that if there is new hyper-v instances then those are not automatically picked up for backups.
I have environment that have about 40 hyper-v instances and finding problematic ones is now fun task.
In some cases customer have overcomed the issue originated after installing Windows 2012 R2 update Microsoft update KB2919355 by applying MS fix KB2966407
If you have already applied this fix, I would recommend you to raise a case with EMC support and request the fix provided under NW161433 for NW 3.0.1

Hi Mandri,
I see in the logs some permissions issues:
Unable to render the following message: 100127 1403606596 0 0 0 7884 8176 0 dc-ch1b2-hv.corp.local nsrsnap_vss_save NSR info 52 NMM %s the

This is an OS/Application error message, so you will need to check in Windows, AD or Hyper-V the permissions. Have you checked that?
Thank you,

Good afternoon.
I think this is a eroor on the side of the EMC Networker. Such errors occur in some other backup products and they release patches/updates:

Hello,
Does anybody know if this issue was resolved ?
I have the same issue, after we installed Microsoft Hotfix KB2919355 and also KB2966407 still the Hyper-V jobs don't work.
Thanks in advance.
Best regards,
CatalinM.
