What Windows group is needed for a service account for Netbackup enterprise master server

[Cls_64]

I have read many articles but still have not found right solution for my question ?

We have a profile called "corpbackup"

to this profile "domain admin group" is added which is not appropriate.

What Windows 2008 group is needed to really run the Netbackup enterprsie backup services. For example "Backup Operators"

We dont want to use local admin accounts but the goal is to have enough rights to the domain profile so the services dont stop.

You can add domain accounts which you want to be the Netbackup admin to the local administrators group. In a nutshell, a local administrator required in order to fully manage Netbackup.

Anyways I dont understand why service would stop if you use local admin to manage Netbackup.
