With the launch of OS X Mountain Lion, Carbon Copy Cloner has made the transition from donationware to commercial product. The cloning software that makes a bootable backup of your hard drive will be $29.96 until August 12, then the price rises to $39.95. A free 30-day trial is available.
To run CCC on Mountain Lion, you’ll need the new paid version. I use CCC all the time, and have no problem paying for it.
