So, here’s the deal: You’ve managed to acquire the data, but disaster strikes, and your time machine is destroyed by an enemy time traveler team. This is crucial historical data that you’ll have to get into the future to avert the apocalypse. Due to the constraints of the space-time continuum, all time travelers staying outside of their “home” time for longer than 1 year will die, so you have exactly 1 year to prepare. How do you make sure the future discovers the data, while preventing the enemy time traveler faction from stealing the data?
(Remember: don’t just chuck it in a hard drive and bury it in a forest somewhere, the data will degrade)
As a time traveler I expect to have knowledge of what readers exists. verbatim makes archival grade DVD, blu-ray, and CD media guaranteed to last 100 years. Put copies on a couple different time capsules and I’m good. However I don’t have much confidence that media readers for any of this will exist. Even if I put a reader in the time capsule I’m not confident it will survive - the media will be good but the mechanics probably are lost to corrosion, so this is the most important part.
Does it really need to be all 100tb? Can I find a small subset that matters? We have history of payrus scrolls with the correct ink that have a proven history of lasting thousands of years when left in a desert garbage dump. You can find the recipe for making both the scrolls and the ink in the bible. Copy by hand, leave in the desert, in a location I know archeologists will dig in 100 years. This is very limited amounts of data that can be saved though.
If the above doesn’t work, non-acid paper when laser printed (not inkjet!) should last plenty long. Again I don’t think I can get anywhere near your 100tb, but I remain convinced everything we need can be archived on it.
