Alex,

This is indeed one of them. Unfortunately we still have no news if this is solved or not in the latest rollup update.

Application-aware processing of Active Directory domain controllers running on guest OS other than Windows Server 2016 fails with the “Failed to create VM recovery checkpoint” error (32770). This is a Hyper-V 2016 issue that Microsoft is planning to address in the future update.

I am having this same issue, too.

I've been randomly seeing the Failed to create VM recovery checkpoint problem on a 2012 R2 VM running on a 2016 host. However, this VM is not a DC. It is a file server. So far, when it happens, I restart the VM and backups start working again. I'm hoping whatever change is made to fix the issue for DCs also fixes it for this system. The file server does have DFS Replication and DFS Namespace services running. That's one commonality with a modern DC.

Hi guys,

Thanks for the thread. We currently have a 3 host Windows Server 2012 cluster connected to Dell Equallogic. I built up a new 3 host Hyper-V 2016 cluster connected to a Tintri VMStore T820. It's been running great but I was planning on moving VMs over to it and reading this thread has given me pause. Should I rebuild the cluster to Windows Server 2012R2 instead?

Thanks in advance!

Well i just can speak from a single server hyperv 2016 server Installation. I "just" have troubles with 2012R2 Server with RoDC Role installed. 2012R2 without RoDC Role, 2008R2 and Windows 10 VM Backup is running fine so far

Gostev said that there will be a patch next Tuesday but it is causing instability with VEEAM?

Gostev wrote:Regarding the Windows Server 2016 deduplication corruption issue that I mentioned in the previous digest, be aware that we have one report of KB3216755 (which supposedly fixes the issues) introducing system instability and causes Veeam services to crash on Windows Server 2016. We have the crash dump and are currently investigating - meanwhile, uninstalling the update helps. At this time, the update is only available on Microsoft Update Catalog web site, but presumably will become widely available during the next Patch Tuesday.

The instability should be fixed by Microsoft before the patch goes GA, see thread on this in the main forum.

Sorry to be a pain Gostev but can you provide a link to where you want me to look?

I believe Gostev refers to this thread > Veeam services crash after installing KB3216755, KB4010672

We also see this error after repliacted from a 2012 hyper-v to hyper-v 2016 with Veeam.
Guest os 2012.

Only running 2 vms. The best and easy fix is to delete the vm and attach the .vhdx to a new vm?

well, it didn't work to create a new vm (gen 8). Turned off application aware for now and backup runs fine.
This is a 2012 domain controller VM.

Hey there !

I was recently given a workaround for backing up DCs with AAP enabled.

I tried it on 2012 R2, but it should work on 2012 (haven't tried it).

What you do is :

Stop the "COM+ Event System" service (be careful, it has a few dependencies, such as DHCP Server, so make sure to restart it after).
Restart the "Volume Shadow Copy" service
Start the "COM+ Event System" again (and all it's dependencies).

You have to do this every time the DC reboots.

I wrote a script that is started by a scheduled task, scheduled to run "at startup", which works fairly well.

Use at your own risk (I wrote it, but I can't guarantee it will work for your system), there is no error check on this script, and it was only tested on 2012 R2 with powershell 4.0

Code: Select all
function fStop-Services([string]$serviceToStop)
{
    #Get running dependencies
    $dependent_services = (get-service $ServiceToStop).dependentservices | get-service |Where-Object {$_.Status -eq "Running"}

    #stop dependent services
    foreach ($dependent_service in $dependent_services)
    {
        Write-Host "Stopping " $dependent_service
        stop-service $dependent_service
    }
    #stop service
    Write-Host "Stopping " $ServiceToStop
    stop-service $ServiceToStop

    return $dependent_services
}


function fStart-Services($serviceToStart)
{
    Write-Host "Starting " $serviceToStart
    start-service $serviceToStart

    foreach ($service in $services)
    {
        Write-Host "Starting " $service
        start-service $service
    }

}

$log="c:\scripts\log.txt"

"start" |out-file $log
$services = fStop-Services("eventsystem")


sleep -s 5

#restart VSS
Write-Host "Restarting VSS"
Restart-Service VSS

sleep -s 5

fStart-Services("eventsystem")

sleep -s 5

"end" |out-file $log -append

exit 0


Change $log to a path that will suit you (it only writes start and end when the script runs, erases the file on each run).

Scheduled task configuration
Trigger : "At Startup"
Action : Program/script C:\Windows\System32\WindowsPowerShell\v1.0\powershell.exe
Arguments : -ExecutionPolicy Bypass -file c:\Scripts\Restart-DCOM-VSS.ps1
Change path to actual script location.

Hope that helps.
