mirroring/increments rather than full backups.
there are numerous ways to use rsync as the foundation of a true
incremental backup system; here is one i've used quite a bit:
<http://code.google.com/p/rsync-backup/>
some of rsync's advantages (e.g. backing up only the changed portion
large files) don't kick in unless you are syncing across a network, but
the fact that rsync checksums all files it transfers (and can do a
checksum on the whole fileset) would be one way to improveme on
SuperDuper (which does not verify the integrity of files it backs up)
i also frequently use Carbon Copy Cloner, free from:
<http://www.bombich.com/>
i mainly use it for bootable clones, but it can also do incremental
backups, and provides a GUI interface for scheduling them; however it
isn't quite as powerful for syncing across networks or verifying files
as rsync
btw, i'm not certain what Cotty's goal is with his procedure, but Mac
disks don't really need defragging:
<http://support.apple.com/kb/HT1375?viewlocale=en_US>
so the only benefit i can see to Cotty's wipe & restore ritual is to
avoid filesystem corruption; it would save a lot of time and probably be
just as safe to simply run Disk Utility and verify the volume
periodically; then use the wipe and restore approach only if/when an
error is reported
