    Give CCC a try, you won't believe how easy it is to "clone a drive".

    You can also clone partitions of a drive, to other drives and/or partitions.

    The initial clone will take a while to complete, as it copies EVERYTHING on your source drive.

    Afterwards, "incremental" backups go much faster, because only changed files are copied.

    Also -- if you do a backup clone of your internal (boot) drive, I suggest you do a "test boot" after the clone is finished. To do this:
    - Leave the backup drive connected and powered on
    - Restart
    - As soon as you hear the startup sound, hold down the option key and KEEP HOLDING IT DOWN
    - In a few moments, the startup manager will appear
    - Use the arrow key to select the backup drive, then hit enter/return
    - The Mac should boot from the backup

    Note: doing a "switch-boot" as above does not change the setting in the "startup disk" preference pane. If you reboot again, the Mac should boot from the internal drive as before.
