Ok well the server died a second ago....
Same here. Currently a script hotcopies the database everynight at 3am, and backs it up/plus backs the site files up and stores them on the server + uploads them to a second server (just in case one dies).
Also a store every months backups on DVD, so I have every day from everymonth.. I've only been doing this since the last server upgrade Sept 6th or whatever that was.
