CD/DVD care, handling and storage guide from Institute of Standards and Technology: 
http://ow.ly/3VbgR

CD/DVD's are not used for storage by back up companies because they fade over time due to oxidation. You can slow the process down with proper care, and some types will last longer than others, but you can't stop the process any more than you can stop a photograph from fading. Tape and Hard drives are used because magnetic storage media last much longer. You still have to be concerned about mechanical failure which is why a backup company will use RAID.

Cheers,
Mark
