I use the rdiff-backup tool and a cronscript that looks as follows:
# Remove old
/usr/bin/rdiff-backup --force --remove-older-than 1M /srv/backup/rdiff/

# Do rdiff-backup
/usr/bin/rdiff-backup
--exclude-globbing-filelist /opt/local/etc/rdiff-backup.exclude / /srv/backup/rdiff/


This keeps all backups for one month and backups everything acording to
the rules listed in /opt/local/etc/rdiff-backup.exclude

Which looks like:
- **/lost+found
- **/cache
- **/Cache
- **/tmp
- **~
- **.o
- **/#*
- **/.xvpics
- **/.thumbnails
- **/thumbnails
- **/.nfs*
- **/.gnome-smproxy*
- **/.ee/minis/
- **/.sawfish/sessions
- **/.metacity/sessions
- **/.nautilus/thumbnails
- **/.jpi_cache
- **/mysql.sock
- **/.journal
- **/.pwd.lock
- **.rpmnew
- **.rpmsave
- **/.cddb
- **/epiphany/favicon_cache
- **/.galeon/favicons
- **/.kde/share
- **/.kde2/share
- **/proc
+ /etc
+ /home
+ /opt/local
+ /tftpboot
+ /var/lib/squirrelmail
+ /var/log/rpmpkgs
+ /var/lib/mailman
+ /var/named
+ /var/spool/mail
+ /var/spool/imap
+ /root

The destination catalog is of course another disk than the rest of the
system.
