Abstract
A metadata processing unit acquires the first metadata from a first data storing unit at a first frequency and makes a second data storing unit store the first metadata. A file data processing unit specifies, based on the update history of the first metadata, second metadata that is updated on and after the last acquisition date and time of second file data stored in the second data storing unit, acquires the first file data associated with the specified management data at a second frequency that is lower than the first frequency, and makes the second data storing unit store the first file data. A switching unit switches a read/write process that is performed by using the operation data stored in the first data storing unit such that the read/write process is performed by using the second metadata and the second file data in the second data storing unit.
