Checking backup version Timeout expired (Error MSG)

[mega_IT]

We are getting this error message on a VM backup:
Checking backup version Timeout expired. The timeout period elapsed prior to completion of the operation or the server is not responding.

All other virtual machines backup fine except this one. Any help on this one?

Tyler, I am not sure about this one. Please send job log file to support@veeam.com, and we will investigate this for you.

This was a VSS issue on our Exchange server which was causing the backup to fail immediately when Veeam attempted to access it. The issue was resolved by installing the VSS Update Rollup and rebooting the server.

Tyler, thanks a lot for the update!

We are still experiencing this problem on some of our VMs. It looks to affect them at random. We do have the jobs set to retry, but the retry sometimes doesn't run at all. We're running Veeam 4.1.

We do have a detailed schedule setup, so there should be next to no conflicts on resources when backups are running. Some days a server may backup just fine and the next it will fail. I don't believe we've had a flawless day using it yet.

Hi Tyler, we have a fix for retries available through our support.

I'm getting randomly the same error on Veeam 4.1.2 when backupping some Linux machines (Windows backups jobs runs fine)

"Checking backup version Timeout expired. The timeout period elapsed prior to completion of the operation or the server is not responding"

Thanks, Marco

Make sure you have VSS processing disabled on Linux guests.

Yes, for sure is disabled

This issue is random on two - three jobs out of ten since one week
