Thanks Marianne, I read the manual the first time around and have had another look through it now. It seems as though the 2 most important points are to have a service account running the netbackup client on the evault server which I have had since the original EV10 backups were running. In fact I have also tried to just run the original jobs which I deactivated while waiting for 7.6.0.4.
The second thing was to have the user account configured under the client settings in netbackup which also has not changed.
I am setting the job up the exact same way I did originally but ensuring that I select Enterprise-Vault 11 instead of 10.
One other thing I remembered and have since changed is the bpend_notify and bpstart_notify scripts still had the powershell commands to put evault into backup mode. I have removed these by creating blank files and renaming the originals but alas still no joy.
Are there any logs I can send you that may help to pinpoint the issue?
Regards
Chris
