ABSTRACT:
A backup device and method for automatically backing up the memory of a computer. The device is installed inline between the electrical outlet and the computer, and also inline between the keyboard and computer. The user initiates a backup/powerdown routine by moving a switch on the device to "off". This in turn disables the keyboard and sends a keycode string from the device to the computer to begin execution of a previously specified backup routine. When the backup is completed, the device de-energizes a relay in the power line to the computer which powers down the computer.
