The processor deduplicates unupdated data among data of the first volume. The processor compresses the deduplicated data to create compressed data. The processor stores the compressed data in a second volume of the storage device. The processor selects, when the snapshot is created for two or more generations, the second volume corresponding to each of a plurality of snapshots of generations earlier than a predetermined generation. The processor detects unpopular data from the compressed data existing in the selected second volume based on a reference count. The processor collects and decompresses detected pieces of the unpopular data when the number of the detected pieces of the unpopular data is equal to or more than a predetermined threshold value. The processor combines and recompresses the decompressed data to create recompressed data."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Storage control apparatus","description":"A storage control apparatus includes a processor that creates a snapshot of a first volume of a storage device.
