发明名称 COMPUTING SYSTEM AND DATA MANAGEMENT METHOD
摘要 Proposed are a computing system and a data management method for improving the usage efficiency of logical volumes without lowering the response performance In a computing system that includes a first storage apparatus in which first and second storage volumes are configured, a file storage apparatus for controlling the first logical volume, a second storage apparatus, and an archive apparatus for controlling the second storage apparatus, the first storage apparatus acquires a snapshot of the first logical volume at regular or irregular intervals and stores differential data in the second logical volume, specifies a file for which the consumption amount of the second logical volume exceeds a predetermined threshold, causes the first storage apparatus to acquire a snapshot of the specified file, and if a read request to read the file is supplied, generates the file on the basis of data stored in the first and second logical volumes.
