Also FYI, Windows 2k16 updates can be tracked here.


I've just had a quick read of the August updates and I don't see anything relevant that would solve the backup/prod checkpoint issue.

MS has a least 2 ways to address the problem:
1) fix old(pre-2016) NTDS/ADAM VSS writers - so that these writers become aware that they should not perform autorecovery steps
2) fix 2016 HV server and guest integration components - so that VSS requester in guest creates shadow copy with autorecovery attribute - and this way MS doesn't need to fix VSS writers because writers will perform autorecovery steps just fine

We are experiencing this error on a 2016 Guest OS running a WSUS, not a DC.
Has anybody else those problems with a server not running a DC?

I experienced similar problems on a 2016 guest running DFS. Turning off AAP seems to have fixed it for me.

Veeam support (Case 02296778) has acknowledged that they are unable to confirm that the following issue has been resolved:

Resilient Change Tracking (RCT) returns incorrect changes for VMs which had their virtual disks moved with Storage Live Migration, resulting in corrupt backups.
This is a Hyper-V 2016 issue that Microsoft is planning to address in the future update. Until then, disable the use of changed block tracking for any jobs processing such VMs.

I apologize if I missed it in these 15 pages of posts, but does anyone know if this issue has been addressed or how to track it from the Microsoft side? Presumably Veeam needs to update its Release Notes at each iteration and has this issue earmarked so they know when it can be removed as a "Known Issue", but I am only being forwarded to Microsoft. I cannot find anything that even specifically references this bug...let alone it's fix.

Can anyone offer any further insight?

I have the same problem with Hyper-V 2016 host and windows server 2016 VM with SQL Server 2016. (could not initiate a checkpoint operation: %%2147754767 (0x8004230F). Error code: '32768'.)
But 20% of the incremental backups are working...80% fails.

Is that also a "known" bug from microsoft???

After turning off AAP backup is working fine - but not a solution.

Thanks for the update

First: Welcome to the forums
Second: I doubt this is a known bug. Please create a support call and post the case ID here and the follow-up after investigation

Some answers.

Production Checkpoints on 2k8/2k8R2 Domain Controllers - Not supported.
See this kb https://technet.microsoft.com/en-us/library/dn818483(v=ws.11).aspx

Exchange 2010
Production Checkpoint of a machine running Edge Transport role (ADAM VSS writer). Not supported.

This is directly from MSoft Premier support.
“Microsoft does not support the use of checkpoints on virtual machines running the Active Directory Domain Services role (also known as “domain controllers”) or the Active Directory Lightweight Directory Services role in Windows Server 2008 or Windows Server 2008 R2. For more information, see Operational Considerations for Virtualized Domain Controllers (http://go.microsoft.com/fwlink/?LinkId=159631).”
*ADAM is former name of AD LDS.

Exchange 2010 backups on hyper-v 2016 with AAP enabled. Works. (As long at edge transport role is not installed) This above would also explain why virtualised SBS etc doesn't work on a 2016 host.

Not sure about production checkpoints on AD 2012 or Exchange 2013 (I imagine exchange 2013 is same as above). I understand Veeam is still investigating/clarifying with Microsoft exactly what is/isnt supported in relation to AD checkpoints.

Many thanks to Rustam and Veeam support team for their assistance in getting some answers on this.

In the past I've worked around the Edge-issues by having Veeam trigger a script that stops all Exchanges services on that VM for a while (although if I remember correctly, stopping ADAM is enough) and having it restarted after the backup. Depending on your setup (redundant, balancers and such) there should be no disruption in doing so.
