Using the ClickFree HD700 is most probably one of the easiest ways to do back-ups of your important data.

Instead of pressing buttons and installing software, you only need to plug the device into the USB port of your computer, and you’re good to go. The specs of the 2.5-inch SATA hard-drive are average, but there is one important detail that could be improved: storage capacity. Only 120GB for a back-up solution? Oh well…

The ClickFree HD700 costs $170 and is compatible with USB 2.0 (and 1.1).
