Best way to backup entire 2k17 game

I don't play this much lately, and want to free up some disk space, but also don't want to lose this if/when it gets removed from the Steam store.

I think if I completely backup these 2 folders, I will be able to restore them later and get the full game back:
C:\Program Files (x86)\Steam\userdata\*random number*\385760\remote
C:\Steam\steamapps\common\NBA 2k17 (this has data + modded folders)

Does this sound correct?

You'll still be able to download the game if it's in your library, even after it's removed from the Steam store. The official patches will also come through. However, the in-game updates (rosters, tuning fixes, etc) won't, so you'll definitely want to back up those folders so that you've still got those assets. You might also want to back up the NBA 2K17 folder under %appdata%\2K Sports, but those three should be sufficient.

Andrew is right.
The only folder you should keep is <main-Steam-folder>\userdata\<user-id>\385760\ which contains yours saves (myleague / sliders / rosters)

Thank you for the info!
