If you are playing on PC, make sure the "saves" folder in "game" folder stays there when you are updating your files. On Android, IIRC you can just install the update APK and it'll retain your save file while updating the game.
would it be a smart move to copy the save folder somewhere else just in case? and plop the save in? i asume this is what you mean
Sure, you can take an emergency backup, just in case.
