There are 2 issues with backups, losing the drive or issuing the wrong command, and someone stealing your computer or having the house burn down. I run mirrordir every night to a spare drive to cope with the former, and backup (too infrequently) to CD-R for the latter. sbisson sounds like he has both covered. Now I've ripped my CD collection I suppose I should offsite that, but its too many CD-Rs for me to bother. If I can get a MP3 player for the car perhaps I'll ship off the CDs then.
