Problems in Computer Conservation
sobachatina writes "The Computer museum at The University of Amsterdam has an interesting page with examples of the problems that they run into maintaining 20+ year old hardware such as rubber rollers from card readers melting or mold growing inside CRT terminals.I hate it when I get mold growing inside my monitor!"
Interestingly enough, the old technology is not considered the best, at least not as a backup medium. This is the thing most of the preservation efforts go and should go into.

Admitted, paper lasts very long, there is enough ancient evidence
But look e.g. here http://www.osta.org/technology/cdqa13.htm,
they say that CD-Rs last 50-200 years(!)
Compare that to magnetic tapes, discs, etc.
But the final solution for very important data may well be the engraving into gold-plated aluminium, as the NASA did it for pioneer 10...
It seems that mechanically changed media (stones, CD recordables etc.) have the longest lifetime.
