To accommodate a low bandwidth network connection or to reduce network traffic, you can do the following:
Reduce the frequency of job status updates that are sent from the managed media servers to the central administration server.
Prevent jobs that are created on the local managed media servers from being monitored by the central administration server.
Reduce the frequency that job logs and job histories are sent from the managed media servers to the central administration server.
Increase the amount of time that Backup Exec waits before changing the media server's status if the media server becomes unresponsive.
Keep the catalogs on the managed media server (distributed). If there is a persistent network connection between the central administration server and the managed media server, then you can browse the catalog and perform restore operations from both servers, regardless of the catalog location.
