I wouldn't count on 'put it in the cloud' being the answer, for a number of reasons.
Personally, I think that the only answer to the "preserve the family stuph for a 100 years" is to migrate it all to the most reliable media available every 5-10 years (it used to be every 3-5 years). Even if there was an archival media that was 100% reliable 100 years from now, will there be something that can read it?
