The Backup Exec operators (beoper) group contains the names of the users who have permission to back up and restore the Linux servers.
When you install the Remote Media Agent for Linux Servers, Backup Exec creates the beoper group and adds root as a member. Any Linux user that you add to the beoper group gets the necessary permission to back up and restore the Linux servers.
However, if an NIS server is detected during the Remote Media Agent installation, Backup Exec cannot create the beoper group. You must create the beoper group manually on the Linux servers on which you want to install the Remote Media Agent. You must create the beoper group before you start backup and restore operations. Otherwise, connections fail between the Linux servers and the media server.
Before the members of the beoper group can perform backup or restore operations, they must have a Backup Exec logon account.
