How to save games save files?

[[RK] Kaiser Zero]

Hi I just wonder if I could backup my savefiles into a external hard drive. Just the save files just in case my CPU got formatted so I can still play my games on the last saved game. Is there a tutorial on how to do this?

Many games use the SteamCloud to sync gamesaves.
You can also use tools like:
