  • Publication number: 20250147850
    Abstract: A system managing apparatus decides a time optimum for executing data copying from a copy source volume to a copy destination volume, and manages an RPO requirement of a user and a quiescing time period for each application at the time of a copy start. The system managing apparatus calculates a copy execution time and a copy execution interval such that data in which application consistency is maintained can be acquired at an interval that satisfies the RPO. In addition, the system managing apparatus monitors the use status of an application and the use status of a copy line after the start of copy operation, and calculates a copy execution time and a copy execution interval that allow a return to an appropriate recovery point, taking into consideration an application quiescing time period and a period of time required for copy completion that change in real time.
