Susan,   Yes, media can fail anytime so it is always a good idea to have two
copies (preferably on two types of media.)  Lifespan beyond 10 years is
pointless anyway because you will most likely want to take advantage of
bigger and speedier and cheaper storage devices.  Don't sweat it, keep
moving.
