Wouldn’t the other risk be that after you’re dead and stop paying the data is deleted or inaccessible?
Maybe if you could prepay 100 years it’d work?
If you wanted to make a sort of digital time capsule and didn't care who discovered it, your next best bet would probably be the Internet Archive or some other archival community.
If your data isn't appropriate for archival (i.e., can't be publicly consumed) and isn't interesting enough for your friends/family/etc. to keep around on your behalf, keeping the data is purposeless.
Though considering these comments and the advent of mRNA/CRISPR, perhaps we could store data for future generations in our own DNA. That'd be fascinating if you could read journals or even audio/video of your ancestors from your biological inheritance from them. What if we could engineer an extra chromosome to do just that, then let them remix and recombine segments of memories so everyone's would be unique.
By comparison, we'll create more data in the next ten minutes than entire centuries from our relatively recent history. Lots of stuff is getting preserved in lots of places with substantive redundancy for virtually nothing. Your slippers today are likely to be more valuable than the near-infinite troves of documents and photos and whatever else.
