Just a suggestion, turn on time machine and use a pertable hard drive. I have a presentation that I have a ton of time in on the same machine and OS that you do and would die if I lost it. I purchase 2 one TB Passsports from Apple and always have at least one of them connected when I am working on the presentation.
