VSS errors

Post by robertb24 » Oct 04, 2019 8:02 pm

I have a Server 2016 Essentials box with and RDX drive and a NAS box target.
Constantly getting the below and failing to backup.

Any ideas?

Hello,
yes: in general, there is are forum rules to not post errors without referencing to a case number :-)

second: there are several KB articles that deal with VSS issues. Just run the VSS commands manually and fix the errors before running Veeam backups. Veeam relies on working VSS.

I would start with this one https://www.veeam.com/kb1980

Best regards,
Hannes
