A remote copy system includes: a first storage system providing a main site; and a second storage system providing a sub site. A storage controller stores data and an operation processed in the main site as a main site journal, sends the main site journal to the sub site for sequential processing, stores data and an operation processed in the sub site as a sub site journal after a failover to the sub site is performed, and cancels an unreflected operation that is not processed in the sub site after being stored in the main site journal prior to the failover in the main site and sequentially processes the sub site journal in the main site, when a failback to the main site is performed."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Remote copy system and remote copy management method","description":"A failure in a main site is recovered by operating in the same operational environment as a sub site.
