US Patent 7814365 Backing up selected files of a computer system

A system and method for providing substantially concurrent mirroring of files across a network. A data file is selected for mirroring on a local computer system and one or more remote computer systems are designated to store a back-up copy of the selected data file. As changes to the selected data file occur, change information is captured by a mirroring driver, which is attached to the file system driver, and then forwarded from the local computer system across the network to the remote computer system or systems. Each remote computer system then updates the back-up copy of the data file.
