Backup of Domaincontrollers breaks SYSVOL

Post by Flori »

Hello,

did anyone stumble accross this problem?

I think since the upgrade to version 12 every time I backup my domain controllers (VMs on Hyper-V) breaks my SYSVOL replications so I have to do a authorative sync afterwards.
At the moment I disabled the backup and the problem doesn't occur any more...

Hi Flori,

what is the support case number with the logs?

Veeam processes consistency through the Microsoft VSS framework. Basically Microsofts own VSS writers bring their own Software including active directory in consistent state. We just orchestrate it.
What are the error messages in the Windows Event log?
Do you have enough space on all drives that Microsoft VSS can perform temporary snapshots of the filesystem (min 10% free space).
