A VSS critical writer has failed

Post by andreas2012 »

Hi,

I have removed backup exec from a physical server and installed veeam agent for windows. I am just trying to backup a simple directory to see if it works, but it fails with the error below.
I know there is Oracle on the server, but I should be able to backup a simple folder that has nothing to do with Oracle. Any suggestions why this fails ?

Code: Select all
