Setting up device pools offers the following
Automatic job rescheduling. If a device fails while
a job is running on it, that job is rescheduled and placed on hold.
Other scheduled jobs are rerouted to working devices in the device
Concurrent processing. Devices in the device pool
run different jobs at the same time, allowing maximum hardware
Dynamic load balancing. Jobs are more evenly
distributed between all of the devices included in the device pool
when running simultaneous jobs.
Cascaded drive pools. Drives of the same type are
linked together so that large backup jobs that exceed the capacity
of the media in one drive automatically continue on the media in
the next drive that is defined in the pool. The cascaded drives
appear logically as one device.
