PROBLEM TO BE SOLVED: To provide a data duplication system, a duplication method and a program, which facilitates incorporation of a data duplicating function and management of duplicate data. SOLUTION: A save function 2A stores normal data, and stores copy source data for paste. A load function 2B reads the normal data, and restores the copy source for paste by object from a specific file for copy and paste. A copy function 2C specifies copy source data, and creates a data file for paste by using the save function. A paste function 2D creates the duplicate of the copy source necessary for paste by using the load function. COPYRIGHT: (C)2010,JPO&INPIT
