Affected area:	\Backup Using Child Partition Snapshot\GVASCCM02-New
Occurred since:	22/11/2012 18:11:33
Description:	The replica of Microsoft Hyper-V \Backup Using Child Partition Snapshot\GVASCCM02-New on SCVMM GVASCCM02-New Resources.GVAHYPERV00.EUROPE.loc is inconsistent with the protected data source. All protection activities for data source will fail until the replica is synchronized with consistency check. You can recover data from existing recovery points, but new recovery points cannot be created until the replica is consistent. 

For SharePoint farm, recovery points will continue getting created with the databases that are consistent. To backup inconsistent databases, run a consistency check on the farm. (ID 3106)

Hi elsaxo,

The most common reason because of which you might run into this situation is when the Hyper V VSS writer is in failed state. To validate it, please consider the given action plan :

1) What does this VM host? Is it file server? SQL server? Exchange server?

2) Does the VM backup fail on all the nodes or just on this specific node? What happens if we fail the VM over to another node and then try to back it up?

3) On the given Hyper V node - run the following command over a command prompt with admin priveleges : vssadmin list writers.

4) Run the same command on the VM as well and provide the output of both.

5) Also look at the event viewer (Application logs) on the Hyper V node and look for any VSS related errors. If there are any please paste the errors.

6) If the Hyper V VSS writer is in a failed state then please restart the Hyper-V Virtual Machine Management service under services console. Please remember when we restart this service, we will loose the connection to the virtual machines active on this node till the time the service does not restart.

Will look forward to your response.

Hi ,

I have faced this issue.

Error snapshot.

I am taking backup of SQL VM Machines, I have already took the backup of all vm, only SQL VM is Creating issue.

Opened Command Prompt, type vssadmin list writers in Both Hyper-V node, find error in one node.

Error is  Hyper V VSS writer is in a failed state

I have stop Hyper-V Virtual Machine Management Service in that node and then retry the Backup from DPM but is again failed

I have migrated the VM to another node, part of same cluster, and try the backup, it again failed.

then i stop Hyper-V Virtual Machine Management Service in both nodes., deleted the Protection group for SQL VM.

Cross check the Free space in all volumes of SQL, Cross check the Integrated Hyper-V guest Services Version, Recreated the Protection group for SQL.

Finally it starts working...

Hi All,

We have faced same issue again in DPM 2012 R2 installed on Windows 2012 R2.

Reported issue: backup failed of only one VM machine, after deletion of .avhdx file directly from Clsuter volume instead of Hyper-V Console after poweroff, so someone follow-up wrong approach and we are facing 3 issues

Issue1: unable to export VM machine online as well as offline

Issue2: Unable to do live migration

Issue 3: Unable to take DPM Backup..

So,

We have follow-up mentioned 2 approaches to fix backup issue of one VM machine via DPM.

Approach 1 :

Step1 : Power off VM Machine, tried export of VM machine, which is failed, so we done Changes in time interval inside DPM Protection Group to schedule Tape backup-> after that Tape Backup failed.

Finally we used  Approach 2:

Step1: copy vhd file of VM Machine in another Cluster volume, created new machine with existing vhd and done hardware configuration and assigned same IP address.

Step2:  power off VM machine and added it in failover cluster, power on again and done live migration which is successful.

Step3:  Created new Protection group and started VM backup, which is running now

Thanks for reply, but I just migrate VM to another CSV and work, and I guess this is a workaround
