Hello!
I think I ran under situation explained here: https://support.symantec.com/en_US/article.TECH74570.html but I can't find the key information I need: What is the correct permission to grant to my service account to prevent this situation.
Let me explain the situation in a few words:
I have a Windows cluster with 3 clustered SQL Server (2008R2) and NetBackup 7.6.0.4 (LAN and SAN mode)
Each SQL Server runs under a specific service account: Let call them "sa_instance_a", "sa_instance_b" and "sa_instance_b"
"NetBackup Client Service" and "NetBackup SAN Client Fibre Transport Services" run under another service account : "sa_netbackup"
Concerning the configuration, 2/3 of my SQL Server are backed up through LAN and the last one through SAN. There is no problem with the LAN one's, I can backup them with my personnal account (which is part of computer's administrators)
With the one that is backed up through SAN, I can't backup or restore (using the "NetBackup MS SQL Client") if I don't use the specific service account "sa_netbackup". Using this account is not a pretty solution for me since it could be used by a lot of people. I would prefer that they use their "usual" account like they do for the instance backed up through LAN.
When I read the technote, I thought that would be the solution but I can't find what permission should be granted to which service account.
The error I get is: "<4> handshake: Not a candidate for alternate buffer method because the NetBackup client service account does not match the account used for launching the backup".
Thanks for your help on this!
