I've have two B2D devices in a device pool, and set my backups to use that device pool.

My weekly full backup at the weekend failed when the first device became full. I thought that the main

benefit of using a device pool was that when one device became full, the job would switch to the next.

I've just manually restarted the job, and it's started using the second device, the one with free space.

I've tried Cascaided Drive Pools, which would appear to do exactly what I want, except that it's for tapes drives only, not B2D folders.

Have I missed something? Is there a way of getting jobs to auto switch devices as they become full?

Thanks.
