A client and a system for file backup are provided to perform a backup operation as to files by file unit by backing up the files in real time based on a file control message. At least one application program is prepared, and a device driver(200) generates the backup files as to the files that a message indicates among messages created at a window Kernel. A Kernel message filtering unit(210) watches the messages generated at the window Kernel and extracts the messages which controls the files. A copy generating unit(230) extracts a file path that the extracted message indicates, and generates the backup files about the files that exist in the extracted path.
