We setup a new job recently on our Backup Exec 12.5 server. One of the jobs had the following error:
Backup Exec could not find a Microsoft Volume Shadow Copy Services (VSS) software or hardware provider on the media server. To use offhost backup, a VSS provider must be installed on both the media server and on the remote computer.
The solution to the is actually easy. It was a mistake we made in setup of the Backup Job.
All we had to do was un check the option in Advanced Disk-base Backup.
Hope this helps others.
