摘要：
A controller sets a specified time which is a time that specifies a time in the future relative to the current time for all of one or more secondary storage systems. The respective secondary storage systems have a logical volume for backup (BVOL), and set a backup preparation end state when a journal up to a specified time has been established, and report information showing a preparation end state to the controller. The controller issues a backup command to all of the one or more secondary storage systems when information showing a preparation end state is reported from all of the one or more secondary storage systems.
