Mike Bombich has released Carbon Copy Cloner 1.2.2, an update to his OS X-only cloning utility developed with AppleScript Studio. It assists users in backing up or moving OS X installations from one partition to another as easily as possible. Version 1.2.2 adds "Authenticate" to the File menu, sets the target disk to be the startup disk when finished, and fixes a permissions problem that affected items copied to the root level of the target disk.

Can stall
I've used CCC 2.0 and it stalled at one point.
To remedy this, force quit the app, type top and find the PID of ditto. Then type sudo kill -7 [PID].
Restart the CCC app and continue cloning, ensuring that you've activate the synch option, so you don't have to sopy all the files again.
