## Background
CLAIM OF PRIORITY TO PRIOR APPLICATION
This application claims priority under 35 U.S.C. § 119(e) to U.S. provisional patent application Ser. No. 60/187,843, filed on Mar. 8, 2000, incorporated herein by reference.


FIELD OF THE INVENTION
Embodiments of the present invention are directed to a method and system for remotely backing-up a computer memory utilizing a global communications network. More specifically, embodiments of the present invention are directed to a method and system that remotely administers a memory back-up procedure, ensures that the memory back-up procedure is successfully completed, and automatically performs necessary repairs.
BACKGROUND OF THE INVENTION
Backing-up computer memory essentially consists of making a copy of the computer's hard drive and storing that copy in a remote location. It is well known that errors in back-up procedures occur frequently, however, these errors may not be detected and repaired until days, weeks, or months after the back-up procedure has been performed. The errors may result from mechanical failures, computer viruses, natural disasters or human error.
With the advent of the INTERNET, systems have been developed to provide computer back-up services by remotely connecting to a customer site to perform a computer memory back-up procedure. However, many individuals dislike the idea of providing a memory backup procedure through an open media like the INTERNET. Transferring private files over the INTERNET may compromise privacy, and may seriously damage any data in the files. Furthermore, processes for efficiently transferring large data files utilizing the INTERNET typically require very expensive wideband T1 connections.
Typically, speed of data recovery is not a concern. However, a memory back-up procedure that requires 10–20 minutes is preferred over an off site memory storage facility that may require as much as two days to recover any stored data.

DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention are generally directed to a method and apparatus for automatically backing-up a computer system and ensuring that the back-up was successfully completed. In particular, embodiments of the present invention are directed to a method of remotely backing-up a computer system and utilizing a global communications network to ensure that the back-up was successfully completed. Embodiments of the present invention will now be described with reference to FIGS. 1–2.
FIG. 1 is a schematic diagram of a communications network 100 that implements a method of the invention. The communications network 100 includes a central office 120 that further includes a first computer 112. The central office 120 is in electronic communication with a plurality of computers 160. The plurality of computers belongs to various customers that request the back-up procedure of the invention. The central office 120 is in communication with the plurality of computers through a global communications network 140, such as the INTERNET. In general, the first computer 112 located in the central office 120 connects to the global communications network 140 through a modem 110. The modem 110 is in electrical communication with a telephone line 145 that connects to the global communications network 140.
Typically, the global communications network 140 includes an internet service provider (ISP). In one embodiment of the invention, the ISP facilitates an electronic connection to the plurality of computers 160 through the telephone line 145. In one embodiment, the computers 160 are individually connected to separate automatic transfer libraries 170. In one aspect of the invention, a dedicated electronic link 165 is provided. The dedicated electronic link 165 connects the automatic transfer libraries to one of the plurality of computers 160.
In one embodiment, a communications network may comprise one or more telephone lines or other networking system to operatively couple a first computer 112 with a computer network 120 or a second computer 162.
Utilizing the communications network 100 shown in FIG. 1, the first computer 112 receives a ready signal from a customer's computer network 160, and the first computer 112 electronically connects to the customer's computer network 160 after passing through a firewall 150. The first computer 112 administers a transfer of data to the ATL 170 as described hereinbelow. Upon termination of the data transfer, the first computer 112 sends an appropriate electronic message that the data transfer was successfully completed or repairs are required. If repairs are required, then the first computer 112 may remotely perform any required repairs, or notify the local administrator that human intervention is required.
Referring to FIG. 2, a flow chart 200 shows the steps of a method of the invention. Specifically, the flow chart shows the steps of a method that utilizes a global communications network, such as the INTERNET, for electronically backing up a computer system and for ensuring that the back-up was successfully completed. In one embodiment of the present invention, the first computer 112 receives a ready signal from a customer's computer network. The steps of the method further include electronically connecting to the customer's computer network (Steps 205–220), performing a back-up procedure (Steps 230–245), and sending an appropriate electronic message that repairs are required. In a further embodiment of the invention, a step of the method includes remotely performing required repairs (Steps 250–265).
In one embodiment of the invention, a step of the method includes a central office computer receiving an electronic message from a second computer 162 (Step 205). In one aspect, the second computer 162 belongs to a customer that is a member of an organization that provides a computer memory back-up service. The electronic message behaves like a ready signal that prompts a first computer located in the central office 120 to begin the back-up procedure. The first computer 112 is located in the central office 120 of the organization that provides the computer back-up service. The back-up procedure begins when the first computer 112 remotely connects to a second computer 162 located at the customer's place of business or a computer storage facility (Step 210).
The first computer provides an electronic identification signal to the second computer 162 (Step 215). In one embodiment of the invention, the electronic identification signal includes a cryptographic or encoded message sent by the second computer 162 that is only recognized by the first computer 112. Likewise, the first computer 112 may respond by sending an electronic signal that is only recognized by the second computer 162.
After an electronic connection is obtained, the back-up procedure may begin (step 230). Throughout the back-up procedure the electronic connection is continuously observed. In one embodiment of the present invention a security check is used to validate the private key (Step 220). In that embodiment, if neither the first or second computer recognize the numerical combination, then the electronic connection is closed, the back-up procedure is terminated and a record of an electronic path is recorded by both computers. The electronic path serves as an electronic fingerprint that may be used to identify any attempted breaches in security.
At Steps 235–245, the back-up procedure begins by transferring data from the second computer 162 to an automatic transfer library (ATL). In general, the ATL 170 is a data storage facility that may be located at a site of the customer's choosing. In one embodiment of the invention, the ATL 170 is in electronic communication with the first computer. In one aspect of the invention, the ATL 170 has a dedicated electronic connection to the second computer 162, and the ATL 170 is not directly linked to the global communications network. Data is transferred from the second computer 162 to the ATL 170, and the first computer administers the data transfer. A person of ordinary skill will appreciate that the transfer of data does not occur over open network lines. As a result, an added level of data security is provided to the customer because the possibility of tapping electronic lines to obtain a stream of confidential data is reduced.
In the method of the invention, the first computer administers the data transfer to the ATL 170. The first computer may also check for any errors that may have occurred during the data transfer (Step 250). If an error occurs, then the first computer may provide a remedy to fix a source of the error (Steps 255–270). As a result, the error is automatically corrected, the back-up procedure is not halted unnecessarily, and a human administrator is not required to intervene. However, if the error requires human intervention, an electronic message may be generated that identifies the problem and suggested solution (if any), and sent to a local administrator (Step 260) or to a technician that may be dispatched to the site to perform any necessary repairs. In one embodiment of the invention, the electronic message is in the customer's standard language. In addition, the method of the invention requires an acknowledgment of the electronic message by the local administrator. In this way, the error is corrected and the back-up procedure can be reinitiated at any time.
A method for automatically backing-up a computer system and ensuring that the back-up procedure was successfully completed has been described above. Embodiments of the present invention include a method of remotely backing-up computer systems utilizing a global communications network to ensure that the back-up was successfully completed. The steps of the method include utilizing a first computer to receive a ready signal from a customer's computer network. The steps of the method further include electronically connecting the first computer to the customer's computer network and performing a back-up procedure. The back-up procedure includes transferring data to an automatic transfer library 170 located at a site of the customer's choosing. The steps of the method also include sending an appropriate electronic message that repairs are required, allowing the first computer to remotely perform the required repairs, or notifying a local administrator that human intervention is required.
In another embodiment, a system for automatically backing-up a computer memory and ensuring that the back-up was successfully completed has been described above. The system includes a communications network that implements a method of the invention. The system includes a mechanism that remotely connects to a customer's computer through a global communications network. The system further includes a mechanism that remotely administers a back-up procedure that transfers data to an automatic transfer library. Further, the data transfer does not occur over open network lines. Thus, tapping open network lines during data transfer does not occur. Accordingly, a more secure environment for data storage is provided.
Having thus described at least one illustrative embodiment of the invention, various alterations, modifications and improvements will readily occur to those skilled in the art. Such alterations, modifications and improvements are intended to be within the spirit and scope of the invention. Accordingly, the foregoing description is by way of example only and is not intended as limiting. The invention's limit is defined only in the following claims and the equivalents thereto.
