How to Do a Mac Backup to an External Drive (13 Steps)

Download Carbon Copy Cloner (CCC).
Double-click the DMG file you downloaded to mount the CCC disk image. In the window that appears, drag the CCC icon to the 'Applications' folder alias to copy CCC to your Applications folder.
Launch CCC from your Applications folder. The first time you launch the program, click the 'Agree' button in the drop-down pane to acknowledge the license agreement, then click 'No Thanks' to proceed to the main interface.
Select your Mac's built-in hard drive from the 'Source Disk' drop-down menu, then select your external hard drive from the 'Target Disk' drop-down menu. If your external hard drive is not in the list, power it on and connect it to your Mac, making sure its icon appears on your desktop. Leave the 'Backup everything' option selected in the 'Cloning options:' drop-down menu, unless you only wish to back up some of your Mac's data. You can also choose 'Incremental backup of selected items', then specify which files to copy using the checkboxes in the file list that appears in the left pane of the window. Note that the external hard drive must be formatted using the HFS+ file system to create a backup with CCC (see References 1).
Click 'Clone' to begin the process. Then Enter your administrator password when prompted to do so, and wait until the process completes. Be sure that you have rewiewed the backup scheme you've specified in the 'What is going to happen:' field near the bottom of the window.
