The other thing I do is ship the backup files across the internet (encrypted of course) so that they are in another physical location. I backup the whole database to the same file each night (rename the night before's) and then use XDelta http://xdelta.org to find the bit level differences between the backup file last night and tonights, I then send the resulting patch file across the internet (normally 50-150mb for a 20gb database per day) and rebuild the backup file on the other location. Works perfectly... Offsite backups are very important these days unfortunatly. 20gb file processed in less than an hour to create the patch file.
