Freyon47: For the main one i use only
Im storing only low weight games of course without sharing,but uploading something to Cloud even if its set to "private" its not sharing by itself?

timppu: What would be the benefit of downloading your installers from google drive cloud, instead of downloading them from GOG.com servers? You will probably get a more up-to-date version from GOG servers.

To me it makes sense to store the backup installers only locally, so that you can install your games even if you lose internet access (to either GOG.com or Google drive cloud), and you are not limited by your internet download speeds.

Ancient-Red-Dragon: The point would be to add security to the backup copy.
If you think having only one backup copy, on a single HDD, makes the copy secure and guarantees that it will be yours forever...well, that is woefully inaccurate information.
That HDD could easily receive hardware damage and make the backup copy totally unusable.

timppu: My GOG game installer library is currently over 6 terabytes in size, counting only English Windows versions of games. It would be even more, much more, if I wanted to keep also other languages and e.g. Linux versions.

How much does it cost to keep a 6-10 terabyte archive online on e.g. Google cloud or similar? I presume the free options do not offer anything near that much capacity.

As long as GOG is around, it is the best cloud backup you can have for your GOG games. They even keep your games up to date for you (yes yes, there are some rare cases where you'd want to keep an older installer as well or instead, but those cases are rare).

EDIT: I tried to find the pricing from Google Drive pages, but it seems quite complicated as it is apparently not based on only the amount of data you want to store in their cloud, but also how much you upload or download and stuff.

Freyon47: 2TB ~10€ month

Freyon47: From what I found out opinions are divided and some think we can store games anywhere and some think it is copyright infringement.

Ryan333: This article is from a few years ago, but it does cite that Google uses hash-matching algorithms to identify copyrighted content on Google Drive:

At the time the article was written, Google was not taking any action on users who were simply storing copyrighted content in their private storage. As many here have said, there's nothing wrong with making a private archival backup copy of a piece of copyrighted media in whatever storage medium you choose, so long as that storage medium restricts access to only you.

The only time Google was stepping in was when people were sharing that content with other users. And that pretty much backs up the notion that the storage medium is irrelevant -- what matters is whether you're sharing the content to others.

MasterW: Did you miss the Snowden leaks? Google knows exactly what files you are storing on theirs servers. And no you can't sue them for millions.
