Prevent Backups From Monopolizing Devices

Limit the number of devices that NetBackup can use concurrently for each policy or the number of drives per storage unit. Another approach is to not put some devices under Media Manager control.

You can also place some drives in a down state or limit the number used concurrently in a specific storage unit. For example, if there are four drives in a robot, allow only two to be used concurrently.
