Recently I ran into issues getting Backup Exec to backup data that was stored on the LeftHand SAN. I was getting VSS errors, specifically HP VSS errors when attempting to backup the data across the network.
Here's was the setup. I had a new LeftHand SAN, an Exchange 2007 cluster that had two mailbox servers with their mailbox stores on the SAN. I had a separate backup server. The SAN's network traffic was completely segregated from the main network, and the backup server was not connected to the SAN network.
What I found the issue to be is that the HP VSS tools had been installed on the Exchange Servers and it was not needed. I had to uninstall the HP VSS and after a reboot everything worked fine for over the network install. In this time I did find that doing an offhost backup would be the best solution, but part of the issue with that for this setup was that all Operating Systems, including the Backup server were not on the same edition of Windows, so it would not work correctly. For now, simply uninstalling HP VSS on the servers that host the data did the trick.
