If this digital data didn't have to be put away somewhere, I would make the most of intelligence. Put someone in charge, with the skills to transfer the data the newer mediums as they become popular and to ensure that the copies are not corrupted in the process. This person would be paid in whatever kind of way leads to the most loyalty, I would also leverage their sense of pride. Maybe have a few different people each tasked with protecting overlapping segments of the data to help ensure nothing is ever lost.

Ideally some kind of artificial intelligence would come about sometime in the future to assume the role of data keeper - hiring people to do any work it couldn't do from within the computer and running off some kind of fund that had been set up. Maybe one day there will be a market for creating intelligent services like this, I hope I have something to do with them.
