On the other hand, I'm thinking of long term archive media, for "long term" on the order of centuries or millennia -- possibly even geological deep time.
The issue here is good indexing and using metadata to keep track of the archived material, not to mention caching and hierarchical storage management. If it takes five minutes to discover exactly what great-great-uncle Bob was doing at 4pm on the damp Friday afternoon in July a hundred and twenty five years ago, I suspect historians can live with that. Hell, if it takes five days to retrieve that data, they can live with it: because it sure as hell won't take five minutes or days to retrieve the really interesting stuff that's already been accessed repeatedly, and it won't take more than milliseconds to seconds to access what happened to you five weeks ago.
