Hi Joshua, what is the exact issue you're referring to? Did you check existing answers to the question in the topic?

What answers are you referring to :)

He's probably referring to the inability to back up VMs with shared VHDXes on a Windows Server 2016 Hyper-V cluster (or host). I'd assume this is still an issue for everybody. I think many of us are at this point assuming that the cause of Veeam not being able to do the aforementioned is due to the inability to create VM checkpoints on the VMs through the Microsoft tools. If that's not the case, let me know :)

I opened a Veeam ticket, and basically got told to pursue the MS checkpoint issue first then come back to Veeam.

See this MS forum for details.

Ah, that's my post on Technet forum. I've been called this morning that finally the bug is found and identified, and a patch will be released most probably June 2017.

@RGijsen,

I learned already that with the new CU update system of MSFT they are not adding all items in the documentation. That being said, I haven't tested that update yet to see that there is a fix and I haven't received any communication about it either so I fear it is not in this one

Our MS rep said the fix is released in August 16, 2017—KB4034661 (OS Build 14393.1613):
[url]https://support.microsoft.com/en-us/help/4034661
[/url]
which hopefully addresses the issues in forum https://social.technet.microsoft.com/Forums/ie/en-US/0d6cddde-3ff3-4a50-a627-6ad7bf7667fd/cannot-create-checkpoint-when-shared-vhdset-vhds-is-used-by-vm-not-part-of-a-checkpoint?forum=winserverClustering and https://social.technet.microsoft.com/Forums/windowsserver/en-US/1e0fa473-896f-4b9c-88f8-e226ee0b6278/2016-hyperv-unable-to-snapshot-backup-guest-cluster-addvmgroupmembers-not-working?forum=winserverhyperv

and hopefully Veeam will also be able to leverage checkpoints to complete backups successfully.
