You're probably better off taking a "small" hd, around 6-10GB, and make nightly incremental, weekly and monthly full backups on that special purpose hd. The hd should be mounted ro to prevent accidential deletion and the like. Based on these Backups you could do a weekly backup to cdr/w as you like. One point I especially don't like about your procedure is, that if you forget to take out the disk of the last day, you would loose two days of backup if the box fails exactly after the disk was erased. And what do you do if you're on vacation, say, two weeks? -- Tschoe, Get my gpg-public-key here Jens http://gecius.de/gpg-key.txt
