Windows 10: VSS Issues with backups on Windows Server 2016 Standard

I have a backup appliance from Datto that is running hourly backups on a Windows Server 2016 Standard File Server. The backups up until about 2-3 weeks ago were working without issue outside of the irregular power outage or two with summer storms. I had an issue where just after the 4th, we started having problems with backups on the file server.

VSS Issues with backups on Windows Server 2016 Standard

I have a backup appliance from Datto that is running hourly backups on a Windows Server 2016 Standard File Server. The backups up until about 2-3 weeks ago were working without issue outside of the irregular power outage or two with summer storms.

I had an issue where just after the 4th, we started having problems with backups on the file server.

We get 1 good full backup, or rather, the server does a differential backup which acts like a full backup, but it compares the other backups on the disk and then writes the changes.

The backup completes after 8-12 hours.

From there, we may get one or two more backups then the VSS writers fail / timeout.

The only way to get the server vss writers to start again, is to reboot the server. If we try restarting Volume Shadow Copy, the server hangs a bit in the process or rather the stop and start process hangs. We have to reboot to get it going again.

The backups will continue to fail with the Datto BCDR appliance until I uninstall and reinstall the agent and repair the agent communications.

But if I do all of this again, I get to the same spot where the server backups fail after 1 or 2 jobs run. The incrementals that are supposed to run should be relatively tiny.

I am planning on trying another backup application in the event this can't be repaired.

Does anyone know of how I can get better diagnostic data as to why VSS is hanging? Why it's failing to backup using VSS? Why I can't restart the service?

 

Windows Server 2016 Essentials upgrade to Windows Server 2016 Standard

I had an OEM version of Windows Server 2016 Essentials installed.

I wanted to use Remote Desktop for 3 users, which essentials cant do.

I have installed an evaualtion of Windows Server 2016 Standard, and have got 3 users remote connecting to the server to run an accounting application.

Thats fine, i have purchased 3 cals for Windows Remote Desktop Services.

My question.

Can i upgrade from 2016 Essentials (which i bought) to Windows Server 2016 Standard, or do i have to buy a new Server 2016 license?

Cheers,

Robin
