I think torrents are the best approach to this thanks to their decentralized nature. they can die if nobody seeds anymore but that doesn’t mean uploading it on some site is gonna make it better as that site can go down too. Besides, if you have a spare laptop you can keep always plugged in and doesn’t consume a ton, you can make it constantly seed your stuff.

I think personally the best approach is through torrents but that’s how I see it. Do what you think works best
