I've automated that by running it in a script after the backup finishes. Still want to modify it so it only compacts when the percentage of free space exceeds a certain amount (or with some other condition; suggestions welcomed) instead of every time.

I'm after practical recommendations from those who have used SuperDuper for some time with long periods of only using "smart backup."

I've been successfully using Smart Update with sparse images for over six months.
