Sparse file support on the backup medium is also very useful if the
backup program supports it. If the utility has compression support,
that's also a benefit to conserve space on the backup medium.

Of course, you could use something like SDFS (OpenDeDup) for the
backup medium and get even greater compression without resorting to
compression or sparse file support in the utility. OpenDeDup is sorta
new, but it does work.
