Most of my CD-R from the 96-00 era have already detoriated to unusable state, CD-R's are bad media. If you have some really important data you want to back up for sure, go for DAT/DLT tape, they're usually promised to maintaid their data for 30+years if stored properly. Cheaper and easier method is store everything on a good quality harddrive and store that in a good place.

DVD-R is worse backup media than CD-R beacuse it is more sensitive to physical damage.

Shiver runs down on my spine because I haven't backed up my studio computer over a year :E
