A system-replication control apparatus includes a processor that executes a process. The process includes: monitoring a use state of a resource in each of data centers; storing facility information indicating resources respectively held by the data centers and a use cost of the resources, and replication condition applied when each system is replicated in a resource of another data center; and selecting a resource composition that satisfies the replication condition and that costs lower than a currently-selected resource, as a replication destination of the system, from among available resources by referring to the use state of the resource obtained at the monitoring and the facility information.
