I wouldn't mind user controlled files but you have a way to back up the game. Just back up the whole folder or the key files or whatever you want like any other data. I am hands-on so typically I run a command line compressor (7zip, specifically) in a batch file over the folder using the task scheduler. But any sort of backup utility will do, dump it to a cloud or usb stick or your other disk drive, whatever works for you.
