Whether you’re making a backup or transferring your data from one Mac to another, Carbon Copy Cloner is an essential utility. Under Mac OS 9, it was easy to move your system to a different drive or Mac: you just selected all your files and folders and dragged them to the new drive or Mac. Mac OS X can’t be copied in that way, but Carbon Copy Cloner does the job. It puts a simple interface on a series of complex Unix-based scripts. Version 2.1 includes several slick new features, including the ability to synchronize files, schedule backups, and create bootable disk images of your drive.
