(There's no video for Carbon Copy Cloner 3.x yet. Please contribute to MR and add a video now!)
The main function of CCC is to clone data from one hard disk to another, for example to replace the laptop unit with a larger model without losing any data. CCC, however, can also be used to make periodic backups of the Mac. Just select a disk drive, activate the folders to be archived and choose a destination, then simply press the clone button.
