Use KSP Backup to back up your quicksave files in Kerbal Space Program. KSP Backup allows you to say "what if I had done this" and then go back to find out. Jump back and forth through time, even create a new timeline. You have the option to restore the quicksave to the original save folder in KSP or you can copy that save folder to a new name and start a new timeline from the same humble beginnings.
**WiFi access to your PC running Kerbal Space Program is required to use KSP Backup**
