I still hope there is some juice in the fruit. Well, there were several alternative methods offered to the OP which ranged from RAID 1 to cheap tape drives on eBay, there were discussions and opinions on reliability of all those, and it went all the way to experiences with repairing a car alternator without proper tools, ways that fire safe works, and such. Oh, and there was a moral discussion on whether the list should give a straight answer to the OP on how to do it, or try to suggest that he doesn't really want to do a backup of 1TB to dvds whilst risking that the OP might get offended by such approach. There were also some clear-cut answers like bacula or dar, if you really plan to actually burn 1TB of data to dvds (on a regular basis?). But all in all, it boils down to what Frank Cox just said (and some people have been repeating from the very start of the thread) --- don't do that, it's impractical and unreliable. Use RAID, use usb hard drives, use networked fileserver or use tape drives. Don't use dvds. Best, :-) Marko
