[OS X TeX] OT: Backup software

I have two backup strategies:
(1) A clone of my main drive, done by SuperDuper!, to be on the safe
side, in case of a hard drive failure or a botched OS update.
(2) Daily incremental backup to a third external hard drive (LaCie
Triple extreme 300GB, fast, silent, excellent) using ChronoSync: the
backup looks like a copy of your original files (for the latest
incremental backup) with a few additional folders containing the
older versions of the files.
With regard to Bruno's dilemma with his mail:
- Either have your mail on the server deleted only by your PowerBook,
or delete the read mail after a longer period, e.g., a week.
- Cc your sent mail from your MacPro to your account.
