Pausing a managed media server prevents the central administration server from delegating jobs to it. When paused, the managed media server's status changes from Online to Paused, and is reflected as such in the Media Server Status column of the Results pane.
When installing Backup Exec options at a managed media server, the managed media server must be paused, so that no further jobs are delegated to it from the central administration server while the installation process occurs. If jobs are running, let them finish or cancel them before beginning the installation.
To pause and resume a managed media server
The check mark appearing before the Pause selection is removed, and the managed media server status changes from Paused to Online in the Media Servers Status column. An icon representing a managed media server in an online state appears.
