The most common ways to destroy optical media is time, sunlight, heat, moist and scratches. Keep it dark, dry and at a stable temperature, and it will last longer, but don't count on it.

How does it fail: CD/DVD/Blue-Ray
Optical media is still a popular form of backup, and for a good reason: It is cheap and lets you keep the copy "forever". But what is that? In general you should not count on a burnable optical media to last for more than 5 years. The chemistry is changed all the time, and the media are made for practically no money in all sort of far east countries, so you really does not know what you got.
