There's a thread about this on the forum not too long ago. I'll repeat what I said there. I don't use CD/DVD for storage. I store them on my PC and on my server (the server is the backup). The chance of them failing at the same time is negligable. If you don't have a server (I can imagine most people don't) I recommend 1 or 2 portable USB harddrives. To be even safer, store one of the HD's in a different location, and I do mean out of the house :)
