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.

Claims

1. A device for automatically backing up information on a first non-volatile memory media of a computer to a second non-volatile memory media upon initiation of powerdown by an operator of the computer, said device comprising:

a power input port;

a power output port connected to said power input port;

a CPU capable of sending initiating instructions to said computer when powerdown is initiated by said operator, said instructions directing said computer to begin running a backup routine capable of selectively backing up said information from said first non-volatile memory media to said second non-volatile memory media;

a memory connected to said CPU, said memory storing said initiating instructions and disconnection instructions;

a clock connected to said CPU;

a means for selectively disconnecting said computer from its power supply, where said means for disconnecting is connected inline between said power input port and said power output port and is further connected to said CPU and where said means for disconnecting disconnects said computer from its power source upon receiving said disconnection instructions from said CPU, said CPU sending said disconnection instructions when confirmation is received that back up to said second non-volatile memory media is complete; and

a computer port connected to said CPU.

2. A device as recited in claim 1 which further comprises a means for initiating a backup process where said means for initiating is connected to said CPU.

3. A device as recited in claim 2 which further comprises a means for canceling said backup process where said means for canceling is connected to said CPU.

4. A device as recited in claim 1 which further comprises a means for selecting an operating mode where said means for selecting is connected to said CPU.

5. A device as recited in claim 1 which further comprises a means for switching, where said means for switching is connected to said CPU and where said means for switching controls from where said computer receives its commands.

6. A device as recited in claim 5 wherein said means for switching comprises a logic gate connected to a keyboard and said computer.

7. A device for automatically backing up information on a first non-volatile memory media of a computer to a second non-volatile memory media upon initiation of powerdown by an operator of the computer, said device comprising:

a means for storing instructions for directing said computer to back up said first non-volatile memory media;

a means for processing said instructions connected to said means for storing wherein when powerdown is initiated by said operator said means for processing directs said computer to back up said information from said first non-volatile memory media to said second non-volatile memory media;

a means for initiating powerdown and processing of said instructions connected to said means for processing; and

a means for selectively disconnecting said computer from its power supply, where said means for disconnecting is connected to and controlled by said means for processing, and said means for processing disconnects said computer from its power supply upon confirmation that back up is complete.

8. A device as recited in claim 7 wherein said means for processing is a CPU.

9. A device as recited in claim 7 wherein said means for initiating processing is a switch connected to said means for processing.

10. A device as recited in claim 7 wherein said means for initiating processing is a keyboard connected to said means for processing.

11. A device as recited in claim 7 which further comprises a means for interrupting processing of said instructions wherein said means for interrupting is connected to said means for processing.

12. A device as recited in claim 7 wherein said means for selectively disconnecting is a relay.

13. A method for automatically backing up non-volatile memory media of a computer when user of said computer initiates powerdown of said computer which comprises the steps of:

A) installing the required hardware and software comprising the sub-steps of;

connecting a backup device to a computer having non-volatile memory media to be backed up, said back up device having a power input port, a power output port, a CPU, a memory connected to said CPU, a clock connected to said CPU, a relay between said power input port and said power output port, said relay being connected to said CPU, and a computer port for sending instructions to said computer;

modifying a boot control file of said computer to include a path to a backup memory location where routines to be used during backup of said non-volatile memory media of said computer are stored;

creating a backup control file able to backup said non-volatile computer memory media when executed by said computer;

storing said boot control file at a selected location accessible by said computer; and

storing said backup control file to said backup memory location;

then

B) maintaining said computer in a normal operation mode; and

then

C) executing said backup control file when operator of said computer initiates powerdown, wherein said executing step comprises running a first routine and a second routine, said first routine backing up said non-volatile memory media and said second routine disconnecting said computer from a power supply connected to said power input port by de-energizing said relay, said second routine running when running of said first routine is completed.

14. A method as recited in claim 13 wherein said computer includes a keyboard, said memory connected to said CPU includes system specific initiating keycodes and running said first routine further comprises the sub-steps of:

disabling said keyboard;

locating and initiating keycodes matching said computer;

then

transferring said initiating keycodes to said computer through said computer port.

15. A method as recited in claim 14 wherein the disabling step further comprises the sub-step of sending a signal from said CPU to a logic gate, where said logic gate enables said computer to receive keycodes from said CPU.

16. A method as recited in claim 14 wherein said locating said initiating keycodes step further comprises the sub-steps of:

determining what mode has been selected by a operator of said computer; and

retrieving said initiating keycodes corresponding to said mode selected from said memory connected to said CPU.

17. A method as recited in claim 13 wherein said creating a backup control file step further comprises the sub-steps of:

creating a backup keycode string capable of backing up said non-volatile memory media to a specified location upon execution by said computer; and

placing said backup keycode string in said backup control file.

18. A method as recited in claim 13 wherein said creating a backup control file step further comprises the sub-steps of:

receiving the backup schedule from operator of said computer; and

placing in said backup control file a datecheck routine for comparing, upon execution by said computer, the execution date with said backup schedule to determine whether to backup or to immediately begin said running of second routine.

19. A method as recited in claim 13 wherein said executing said control file step further comprises the sub-steps of:

monitoring a clock connected to said CPU; and

discontinuing said running of said first routine and said second routine upon expiration of a specified time interval.

20. A method as recited in claim 13 wherein said modifying boot control file step further comprises the sub-steps of:

receiving input from said operator specifying whether backup error detection is desired; and

receiving input from said operator specifying whether capability to backup and power down is desired form a non-operating system command line.

21. A method for automatically backing up non-volatile memory media of a computer when the user of the computer initiates the powerdown of the computer, where the computer has a CPU and a relay connected to said CPU for interrupting power received from a power supply which comprises the steps of:
