The fact that it does incremental backup natively, understanding the
difference between a full and an incremental. It also does many levels
of incremental if you need that (Tower of Hanoi scheme).

The fact that it works on the file system level also has advantages. You
can restore a partition EXACTLY to what it was before. This means
timestamps, ownerships, access times, ...etc.
