What I use to do is make 1 CD backup/archive of my pictures/data that I have, and place it in a fire proof safe - which then after some research learned that even though it is a fire proof safe, it is not rated to keep CD's and such safe - meaning it would probable get warm enough to melt things - but not burn. I had since made 2nd copies of all CD backups, taking the second copy elsewhere out of my home.
I have not actually looked at any of those CD's to see if any of those have gone bad, but recently I opened a pack of CD's that I purchased many years ago, and there were a few brand new ones (few years old) that you could already tell was "going bad".
I'm going to have to dig out the old CD's to take a closer look at them here soon since I'm kind of curious now.
