I use Kopia to perform incremental encrypted backups (with some retention policy of up to two years) and store them on Backblaze B2, which is reasonably cheap.

That, on the other hand, is only viable, if you are sure, data never needs to expire. Dedicated backup solutions work with retention policies.

Where I could see an LLM being useful is categorizing entries and maybe proposing sanitization (for example when the payment provider uppercases or abbreviates stuff)

The cheat developers, yes. Because there is demand. The question though was, why there is demand.

From maybe to definitely not.

If you go for subscription, you accept that the stuff is temporal. Or at least you should. So it should make no practical difference if a game vanishes because it gets pulled from the catalog or if you decide to cancel the subscription because you consider it too expensive.

If it fits your gaming profile, it’s a pretty good deal.
