The media is the answer. (nod to that 60's canadian guy)

TAPE is the storage media for 50+ years, with evidence from the world. There are digital tape files that are 50+.

Other thoughts:
on-line, may not last since ONLINE is a company and you are just a customer bound by their terms which may mean you can't transfer the contents (even upon your death). 

This paper indicates that the longest term storage media is "paper"
