OK, day two with the new UMBP. Everything going great. Files are where I want them, all my programs are installed and running perfect. So, time to backup on an external drive. Is the best method to use time machine for a backup and super duper to clone the drive? In the event of catastrophe, I know I can reinstall OSX and then use time machine somehow. Maybe that's the easiest? Whats the best way to set this up?
