> But you're relying on your chosen cloud-provider staying around for 30 years. Yes, and I recognize that the company existing, or at least that product existing for that long isn't incredibly likely. But I think the fact that there's 3 products from massive companies like Amazon, Google, Microsoft, and 2 from smaller ones, dropbox/backblaze that lasted 10 years means that at the very minimum ~20 years should be considered as realistically possible. And honestly, if we're willing to assume whatever we're storing isn't worth them storing for longer (let's say against your will) - then you should just rekey it anyway yourself. But I'm lazy, and again we're getting to near 15 years for some of those services now. > The number of tech companies that have died in the last 30 years easily exceeds the number still standing [citation needed]. I don't disagree with your premise that the company/product you pick isn't likely to last for 30 years - however I don't think this specific statistic is the correct one to evaluate this with, given the wide range of tech companies with differing products, markets, financial situations, regulations, the many startups that are effectively designed to be acquired, etc. At the very least, I don't think it's fair to compare Google/Microsoft/AWS to "insert latest crypto based file storage startup" in terms of long-term viability.
