No, this is my site.

I modified the ISO VMGuest and the vmbus.sys versions are fine
2008R2: 6.3.9600.17903
2012R2: 6.3.9600.17415

Do not look at the setup.exe version

Checks the XML file: support\amd64\Windows6.x-HyperVIntegrationServices-x64.xml : version 6.3.9600.17903

Insert the iso and force the installation with the cmd command: Dism.exe / online / Add-package /packagepath:D:\support\amd64\Windows6.x-HyperVIntegrationServices-x64.cab / quiet / norestart

And check the version of vmbus.sys .....

Still no update from MS for the backup of a DC2012 on a 2016 Hyper-v host?

I'm fighting with this on 6 2012R2 DC's after upgrading one of our Hyper-V clusters to 2016

These VM's are running Integration Services version 6.3.9600.18398 - I would like to try and downgrade to 17415 as suggested by buburip but I can't see how to do it?

It really is high time MS got this sorted out now.

Hello,

Uninstall the KB3063109 and install Windows6.2-HyperVIntegrationServices-x64.cab in vmguest.iso , see this tutorial : https://www.pc2s.fr/?p=1568

Or here in translation: https://translate.google.fr/translate?sl=fr&tl=en&js=y&prev=_t&hl=fr&ie=UTF-8&u=https%3A%2F%2Fwww.pc2s.fr%2F%3Fp%3D1568&edit-text=&act=url

Or install directly the KB3071740, here : https://www.microsoft.com/en-us/download/details.aspx?id=48207 - Source : https://support.microsoft.com/en-us/help/3071740/hyper-v-integration-components-update-for-windows-virtual-machines-that-are-running-on-a-windows-10-based-host

Is there a general consensus on this?

Uninstall KB3063109
Get the integration components to
2008R2: 6.3.9600.17903
2012R2: 6.3.9600.17415

Bit suck since I can't seem to get my 2012R2 to 17415.....only 17903.

The one at https://www.microsoft.com/en-us/downloa ... x?id=48207 is 17903. And I don't see any of those build numbers here: https://social.technet.microsoft.com/wi ... mbers.aspx

Rather not turn off AAP.....so for anyone who has a 2016 Hyper-V host with a 2012 R2 DC....what have you done and where did you get whatever package?

Thanks. Didn't see the KB3071740 for 2012 R2. Got to 17415, but now I get a new error when trying to backup the 2012 DC.

6/6/2017 8:05:57 AM :: Failed to finalize guest processing. Error: Failed to take in-guest VSS snapshot COM error: Code: 0x80042308

And a bunch of VSS writers are failed (time out).

Tries by disabling "Enable application-aware image processing" and "Enable guest file system indexing" !

Unfortunately I don't have KB3063109 installed - I had to install the 18398 Integration Services manually from a vmguest.iso from one of our other 2012R2 Hyper-V clusters. Not sure if there is another way to uninstall Integration Services.

Veeam, I think this topic deserves a blog from Veeam how to solve this until Microsoft gets this fixed. May frustrated users on a product which has been in production for almost a year..

Hello,

Not to be mean, but the goal of what he's trying to do is making application-aware processing (AAP) work.

So disabling it is not going to help much.

In my experience KB3063109 fixes this COM error, but then you have a version of integration tools that is later than what everyone says allows you to complete AAP backups. It's a vicious cycle :twisted:

Im still stuck with it as well. I've bitten the bullet and have opened a support case with Microsoft about the issue, as I didn't think the work around outlined here are sustainable long term. ie forever checking every update to make sure it is not going to update the integration tools, and subsequently break AAP again. At the end of the day we all still need to be able to patch, and patch regularly.

Ill post an update if Micorosoft can fix. Otherwise plan B is to abandon 2016 Hyper-V host for us for these machines and run up a 2012 host. Very frustrating...

OK guys - an update - no resolution yet.

I now have open support cases with both Veeam and Microsoft about this issue. Despite everyone on this thread saying this is Microsoft issue, if I was adjudicating I would rule in Microsoft favor at the moment. I'll reserve judgement until/if this gets resolved though.

If you are having trouble with this issue, do this to prove the integrity of your VSS architecture.

1) From your Hyper-V host can you take a checkpoint of the machine. If so go to 2).
2) From your Hyper-V host can you use Windows Backup to backup the problem machine? If so go to 3).
3) From your guest VM that is unable to complete a Veeam AAP backup, check the state of your VSS Writers, immediately after completing a Successful windows backup, before trying a veeam backup. Are they all ok? if so go to 4).
4) On the guest VM can you create a disk shadow from the command line? Once complete run 'vssadmin list shadows', can you see the shadow you just created? if so go to 5)
5) Check the state of your VSS writers again on the VM guest. Are they all ok, with nothing in an error/failed state? if so go to 6)
6) Your VSS architecture seems fine!

At this point my microsoft engineer has concluded your "VSS architecture is fine" you can create windows, backups and checkpoints, and a guest snapshot. Everything is working. If you are having problems you need to call the 3rd party vendor."

Try running a Veeam AAP backup again. Backup fails with '32768' error. Check VSS writers. A number of writers in failed state (7) Timed out.

Hang on! I have Veeam telling me it's a Microsoft issue. And now I have Microsoft telling me its a Veeam issue! WTF. I don't care who's issue it is, I just need it fixed. :oops:

Got Veeam on the phone, Microsoft Engineer showed Veeam engineer his findings. Veeam agreed we could seemingly replicate all the steps required to complete a AAP backup. They then both suggested a number of patches to volsnap and vssvc.exe which i have now applied and they haven't resolved the issue.

The case remains open with both Veeam and MSoft. However microsoft have proved they can complete backups using the VSS architecture so at this point im siding with them. If you cant complete the above steps on your server then I suggest you open a support case with MSoft to resolve this first. Its only a couple of hundred dollars, cheap in the scheme of a business, even a small one.

If I get a fix from either party ill post it. At this point I feel like Microsoft have proved their case about their VSS architecture working. I remain less convinced on the Veeam front. If anyone from Veeam has any details on the nature of this 'bug' that causes this issue or a bug id with Microsoft. Can you please it or PM me so I can raise it with my Microsoft support tech?
