Abstract: A method of transparently transferring data between a network application running on a first processor and a target service running on a second processor through a tunnel server running on a third processor, the method comprising: connecting a target program running on the second processor to the tunnel server; connecting a client program running on the first processor to the tunnel server; connecting the network application to the client program through a network adapter running on the first processor; sending data from network application to the tunnel server through the client program; connecting the target program to the target service through a network adapter running on the second processor; and relaying data from the tunnel server to the target service through the target program.

Abstract: A data backup system for backing up a data file from a source device having a source processor and an input device to a target device having a target processor and a database over a communication network. The source processor determines whether the data file has been modified, and if so, determines the modified data block(s). The modified data block(s) are transmitted from the source processor to the target processor over the communication network. The target processor receives the modified data block(s) from the source device over the communications network, and uses the modified data block(s) to construct the data file, and to store the data file on the database. Concurrently, it is determined if the input device is active at any time during the backup process, and if so, the backup processing is interrupted until the input device has been inactive for a predetermined period of time.
