PPROBLEM TO BE SOLVED: To properly select a section necessary for maintaining the matching of a database, and to efficiently generate the backup of the section. PSOLUTION: This backup generation device for generating the backup of a database stored so as to be distributed in a storage device inputs object designation information to designate the backup object database, selects all the storage devices in which at least a portion of the object database is stored, performs quiescent point ensuring processing for the object database, generates backup by copying the whole storage devices in a batch for each of the selected storage devices under such conditions that the quiescent point ensuring processing has been performed, and records the quiescent point ensuring data instruction information showing data whose quiescent point ensuring processing has been performed at the time of generating the backup in each storage device corresponding to the generated backup.
