System management device, system management method, and system management program

Abstract

To provide a system management apparatus, a system management method, and a system management program capable of deriving an appropriate DR configuration based on RTO, RPO, and RLO in a DR using a cloud.SOLUTION: A hybrid cloud system includes a management server, a storage of a source-side data center serving as a remote copy source, and a storage in a cloud service provided from a target-side data center serving as a backup destination. The management server determines a disaster recovery configuration using the storage in the cloud service, based on a target recovery time requirement related to a target recovery time, a target recovery point requirement related to a target recovery point, and a target recovery level requirement related to a target recovery level.SELECTED DRAWING: Figure 1
