Abstract
A computer system is coupled to a local storage system and a remote storage system, and comprises a data mover, and a recall size analysis unit. The recall size analysis unit uses a combination of type of the data and size of the data as a retrieval key of an access characteristics to analyze the logs of the same access characteristics and to determine a recall size for each of the access characteristics. The data mover obtains a target data corresponding to the recall size of the access characteristics of the target data from the remote storage system in a case of receiving a read request for the target data that is not stored in the local storage system.
