Load balancing in disk pooks currently does not work in an optimal fashion.
We are current planning (subject to change) to introduce some enhancements in this area that will allow the selection at the start of a job, of the disk device with most free space, however this enhancement is currently planned for the next full release of Backup Exec and will not be available in the current version.
One thing that is not planned to be changed is the limitation where GRT enabled sets cannot span from one device to another when the device fills up mid job. This is because we have to be able to mount the GRT image from one location to recover individual data from within it.
Note: Spreading the data over multiple disks in the pool in parallel (similar to RAID 5) is known as Multi-Streaming and I believe is something available in NetBackup and not in Backup Exec.
