Well, unless when calculating percentages you round up to the nearest
percent, this still doesn't quite work.

He wants to be sure everything is on tape (so do we, every morning). What
if there are only 2 files in the disk storage pool that total 0.23% of the
backup pool space, and we want to force them to tape. Would migration even
start if I set the High migration threshold to 1%?
