15. A system management method implemented an information processing apparatus that manages a hybrid cloud system that includes a computer system including a first storage constructed in an on-premises environment and a second storage constructed in a cloud environment, the hybrid cloud system being configured to practically apply data copying by which a copy of data of an application stored on the first storage is stored on the second storage to guarantee consistency of the application, the system management method comprising:
acquiring a recovery point objective, an application quiescing time period per unit data amount, a copy data amount, and a copy time period regarding the data copying of the application,
calculating a timing of a copy execution instruction for the data copying that guarantees the recovery point objective that maintains consistency of the application, on a basis of the recovery point objective, the application quiescing time period per unit data amount, the copy data amount, and the copy time period, and
executing the copy execution instruction based on the calculated timing that guarantees the recovery point objective to guarantee consistency of the application.
