NetBackup 188.8.131.52 Exchange 2003 GRT backup failed status 20
This was working before upgrade however I'm now getting this error, I've seen this discussion https://www-secure.symantec.com/connect/forums/net... and understand that VSS is now a pre req, I have tried using VSS but my exchange environment freezes for up to 30 mins during the snapshot phase and then NBFSD fails to mount the NFS share and GRT fails anyway.
I've done numerous tests with manually mounting NFS and have done "System State" and AD backups of the particular server with GRT enabled and they all work fine.
Virtual Exchange server is 2003 SP2 running on Windows Server 2003 R2 SP2 using vmdk's on VMFS datastore on NetApp SAN
NBU is 5220 with puredisk
Any help with why VSS is causing Exchange to freeze ( not the server ) ?
GRT did work a couple of times with VSS but it ran for 14 hrs ( stream backup takes 1.5 hrs ) so I dont see any performance improvements
