Cloning to a disk image will (obviously), not yield a bootable volume unless you use CCC to restore the image to a physical partition or disk.
Now you can setup a regular backup regimen that occurs in the background, even if you are not logged in! Version 2 also offers enhancements for lab administrators, including the option to run pre and post*flight shell scripts, the ability to modify the list of items to be removed at the end of a clone, and the ability to create a disk image on the fly. In addition to the features that CCC has provided in the past, version 2 offers synchronization of the source and target as well as scheduled backup tasks. Have you ever wanted a simple, complete, bootable backup of your hard drive? Have you ever wanted to upgrade to a larger hard drive with minimal hassle and without reinstalling your OS and all of your applications? Have you ever wanted to move your entire Mac OS X installation to a new computer? Then CCC is the tool for you! CCC makes these tasks simple by harnessing the Unix power built into Mac OS X.
