DVD / CDs
Backing up via CDs or DVDs is inexpensive—at first. But backing up regularly will require hundreds of discs over the course of a year. Keeping track, storing, and labeling these discs becomes a management nightmare and they can easily be damaged. In fact, a recent study conducted by the French National Centre for Scientific Research found that that preserving data on CDs and DVDs can do more harm than good in the end. They discovered that the lifetime of discs rarely lasted longer than a few years!
