I know very little about Leopard and therefore I am looking forward to future TMU Podcasts to learn more before switching over. However, there is one thing that is nagging me a bit and I would appreciate if someone can enlighten me. I see that the feature ‘Time Machine” is billed as Apple new backup solution. It will allow backing up to external drives. What I am not clear about is how is this different from using something like SUper Duper to clone my drive? Why use Time Machine?
