I've read somewhere in the TSM documentation a list of the priorities
for tape operations, and I would bet a fair amount of money that
restorations were on the top of the list, followed by several others
such as space reclamation, with backups at the bottom of the list.

This parallels my experience with TSM 3.7 and 4.1, where I've seen a
restore request stop a storage pool backup and a space reclamation.
