Eliza:

At the Disk only Backups Technical Exchange, IBM recommended 2-4 GB volume
size. (This was stated by the presenter, it was not written on the PDF
presentation.)  We started with 25 GB volumes and have now switched to 4 GB
volumes.

Using smaller volume sizes allows a better utilization of space and
increases restore performance with multi-session restore. (Also helps
eliminate contention if multiple clients are restoring from the same volume)
