No entity, large or small is immune from the issue of losing content on magnetic media or film. A few years ago NASA lost up to 20% of the information carefully collected during the 1976 Viking mission to Mars due to it being trapped on a decaying magnetic tape format. NASA had to call mission specialists out of retirement to help the agency reconstruct what was left.
When you consider the massive amount of time and money that was spent to send the Viking spacecraft to Mars in the first place, the magnitude of this loss becomes evident.
