Backing up to magnetic media (hard drive, floppy disk, flash drive, etc) is generally much more reliable over time than any type of optical media (CD, DVD, Blu-ray, etc).

The average optical disk has a life expectancy of 5-10 years with a decent, and consistent, level of care. For many users this level of care is impractical. Everyday use, or constant temperature and humidity levels (among other things), make optical archives unreliable for the average user. Media will therefore be damaged in less time - providing a less accurate, or completely unreadable, copy.

Multiple copies can help alleviate the problem, but are not a guarantee.
