for OT subjects is it forum protocol just to preface with OT and it's cool??

Anway the OT question is what the hell do we do about long term computer storage. I am now told DVD's only last a few years, so you need to re-burn. So what in fact is the solution, we all take a heap of digital images, cars, family etc,, some you print but the vast majority we dont, we store, but there is no long term storage (to my knowledge) so any ideas?
