A method and an apparatus for duplicating a database to plural systems are provided to enable more accurate data synchronization by authenticating data after duplication of the data. An apparatus for duplicating a database to plural systems includes an original source database(200), a plurality of destination systems(310,320,330), a trigger(110) and an IFS(Internet File System) table(100). The original source database is a target to be duplicated. Duplicated data is applied to the destination systems. The trigger checks an amount of changed data of the original source database. The IFS table manages the amount of the changed data and transmits the amount of the changed data to each plurality of destination system.
