Interesting problem. And yes you are right, there are a number
of problems to solve here, see:

That looks interesting, but true archiving is needed. The level of
archiving for this application is that copies would be kept thousands
of feet underground in a stable salt mine on continents 'A' and 'B'.
An alternative is special temperature, humidity, and pressure
controlled above-ground bunkers. It is desired that the data be
preserved for hundreds or a thousand years, which would of course
require copying to more modern media ever so often. The cost to
create the original data is up to $200 million (today's cost) and it
can not be recreated. The size of the originals to be archived ranges
from 2TB to 400TB depending on how "deep" the archiving is.
The existing archive approach is in analog form but it is found that
there is noticeable degredation after 50 or 100 years which is not
possible to fully correct.
When saw a discussion of these requirements today, ZFS immediately
came to mind due to its many media-independent error detection and
correction features, and the fact that it is open source.
