I am a little late to the new improved Carbon Copy Cloner. I just installed the beta for Yosemite and it is very nice. Much more robust than what I used years ago. It is a lot faster than Time Machine. I am liking it. If you would like to use CCC beta for Yosemite, you can sign up for free on their site. Once you verify your email address, you can be up and running with the new beta in a matter of moments.
