During some consultancy projects @ SMB customers where we needed to install and configure VMware VDR to do some backups, we had some issues with Windows Machines and VSS. The result of the these errors with VSS was that the VDR backup jobs all failed.
Here some possible solutions (gonna try to keep the list up to date.)
- VSS could not be started on a Windows 2003 server
We had to reregister all VSS DLL’s, restart the server and everything was working again. (check this)
VMware KB Articles about possible VDR / VSS issues.
Because VDR is taking snapshots of your virtual machines this can also be a interesing KB
