HELP!! I just accidently overwritten my main game save file, what should I do?

@blockhart93  That image is from the PC version. We don't have it on console. For XB1 you only get cloud backups. For PS4 you can use cloud or a USB to back up saves.  

If you haven't backed up in the cloud or on USB, the save data is lost. This is also the way it works for any console game. Save often, have multiple saves and back your saves up.
