Yep, same here, but for Exchange 2013 on 2012R2 VM, backup still fails.

JIT,

Exchange 2013 on a 2012R2 VM, that actually should have been solved already (unless I am mistaken). Did you ever created a support call for it?

I must say Veeam supports response is dreadful, basically just fobbed it off as an MS issue, no evidence that is in fact an MS issue no internal KB that this is a known issue with veeam and no links to bug ID's with MS either basically just left to sort it out ourselves.

Worst of all when veeam has attempted to backup some of these VM's its created checkpoints which then fail to merge when the VM is shutdown and then completely bork the vm itself.
Backup software that doesnt backup supported applications, corrupts VM's and support which isnt particularly proactive, nice one veeam!

Support ID's 02218107 & 02213337
I have this exact same issue now. If I shut these machines down, I'm positive they won't start again because checkpoints exist (based on the disk names), but Hyper-V doesn't know about them.

I just installed the latest updates (as of 2/28/18) and 4 backups ran fine, but now they're hosed again. This is bad. My client just moved his ERP system over to these machines and now I can't back them up.

My support case number is: 02642564.

I ran the updates on 3/1 and thought I was done with this. Very disappointing.

Hello Jeff,

Unfortunately Veeam does not create or delete checkpoints. We only send WMI calls to the Hyper-V host to do that.

This does mean that if you have left over checkpoints or are unable to create/delete them, you'll need to reach out to Microsoft Support.


Thanks,
Mike

Escalated now.

Support is right in saying that we don't create the checkpoints ourselves. We do sent WMI calls to the Hyper-V backup API's. Can you see those checkpoints in Hyper-V manager?

Mike thank you. I see no checkpoints in the GUI, but the file names of the disks in settings all end in avhdx. I have a theory, albeit a novice one - Veeam works for the first few runs, then on the last successful run it doesn't properly merge the checkpoint (or Hyper-V doesn't properly merge it). That's why the next backup run fails - that checkpoint is there.

The only thing I see in the event logs are VSS writer time out errors.

Had the same Problem with Hyperv 2016.
After a remote session with veeam Support, i had to upgrade the Integration services in the vm.
(no Windows updates were available for the vm)
you can download it under https://support.microsoft.com/en-us/hel ... l-machines
You have to install the cab file: DISM.exe /Online /Add-Package /PackagePath:path to cab
After reboot the backup was sucessfull.

The behavior is that an .avhdx file is created and then not removed after the backup. It is not listed as a checkpoint in Hyper-V, but it's there and the VM points to it in its settings.

Strangely, when I power down the VM, eventually the .avhdx file disappears and the VM then points back to its correct file.

Is this a merge that happens after power down? Why can't it merge after the backup is complete?

I wouldn't be surprised if these issues really are Microsoft issues. (It's still poor for support to tell a customer "it's not our problem, go call Microsoft", though.) Have we not learned our lesson to wait for the "R2" release? Windows Server 2003, Windows Server 2008, Windows Server 2012 were all much better in the R2 flavor. And after R2 came out, the original release got treated very poorly. A very recent example is KB4072650. These new integration components were released for Windows Server 2008 R2 and Windows Server 2012 R2 leaving the R1 releases high and dry. I bet Windows Server 2016 R2 will be rock-solid!

none of my 2008 R2 servers can find (or have installed) the kb4072650.
anyone have a link to the .cab file and how to install it manually?

If you are updating your servers via WSUS, have you tried the "Check online for updates from Windows Update" option directly from Windows Update on the VM? I did this by chance and found KB4072650. For some reason, it wasn't showing on my WSUS server as needing approval. So, I manually searched for it and approved it once the search found it to make it available for the rest of the systems.
