Grooves: Storage is dirt cheap now.
Magnitus: Not dirt cheap, but affordable if you are middle class or higher.
Grooves: Cloud storage even more so.
Magnitus: Not when you got close to 10TB of games it isn't.
AWS glacier would cost me about 8$-10$ a month, which is pretty afforable (until I need to download my games if my local backup goes kaput anyways... then they'd hit me with their download cost which would be 700$-900$ for a collection my size), but it has some important access restrictions that need to be taken into account.
Backblaze B2 would be about 40$-50$ a month which is not horrible, but I wouldn't call it a negligible expanse.
Regular AWS S3 would be about 4x the price of Backblaze B2 and that is starting to get pricey.
However, none of those options are as cheap as a pair or redundant drives. It just fulfills a non-local redundancy requirement and because of the prohibitive cloud-to-internet transfer costs clouds tend to have, you use them strictly as a backup and hope you end up not having to rely on it as it will cost you a fair amount of money if you do (but if you end up needing it, the transfer cost is still a preferable alternative to losing all your games).
Grooves: ZERO worries about GOG going out of business.
Magnitus: Because?
Grooves: Whenever I buy a game I immediately download the installer, throw it on my NAS which has redundancy which automatically uploads it to my cloud storage so triple redundancy. Use the tools at your disposal.
Magnitus: Yes, I've started investigating my cloud backup strategy as you can see above with pricing in mind as my collection is rather large.
However, I'm quite busy with work (and have been so for the last ~4 years) and given that GOG currently provides me with redundancy and I got a redundant RAID 10 setup locally to complement that, its not my most immediate priority.
It is something that I'm easing into as time allows.
It comes down to what matters to you. My game collection matters. So I invest in it and the storage to keep it. I pay for the 365 sub that includes a terabyte of storage and then 1TB for 5 other people. So I created accounts for all those slots so I am getting 6tb of storage which auto uploads from my NAS for literally nothing since I need the 365 sub anyways. For the rest I use backblaze. If you can't swing that much I don't know what to tell you.

JakobFel: I would not say "dirt cheap". Even a 2TB mechanical hard drive runs around $50. Given the sheer size of games these days, combined with some GOG libraries being hundreds of games, neither cloud storage nor physical backup storage is particularly cheap.
It really is "cheap" at this point. If you look around there are tons of cloud storage deals you can use.
