I am looking to format my Mac and reinstall everything including the new Mountain Lion. I currently have SourceTree on version 1.6.0.1. I have over a hundred repos setup. Rather than cloning all my repos and losing all my preferences and logins etc. Is there a way to backup my entire SourceTree including all my repos, settings, logins etc. So when I have reinstalled my OS I can just setup SourceTree as it was?
