Hammercorps: So I grabbed the Beat for GOG Galaxy this morning, and as I was poking around , I've noticed that although the GOG staff have said you can download backup installers, I haven't found a way to do this yet. Am I just missing something? Or do you still have to use the GOG.com Downloader and download them from the browser?
Thanks!
Even better,
GOG has now a excellent restore function with can easily restore your previously installed and updated games.
Before reinstalling the System or GOG Galaxy simply copy the folder where you have all your GAMES and paste it somewhere safe. Once you have completed your re installation start the new GOG Galaxy to see if it works. Exit GOG Galaxy. Copy or move your backed up games folder back to your desired location.
Start the GOG Galaxy again. Go to library, choose the game you wish to restore Click the MORE button go to Manage and Import folder. Choose the game directory and let it do its thing.
To restore Witcher 3, 32 gig including updates it only took 250 MB of internet tragic.
Thank you GOG, we love you.
P.S. As far as I am aware GOG doesn't have could save function. So make sure you will back up your saves properly when you are backing up the game as well.
