Abstract
In a file storage that is coupled to a cloud storage storing data and manages a file, the cloud storage compresses and stores the data, and the file storage includes a processor. When data of a part of a file held in the file storage is updated, the processor is configured to compress updated update part data so that the update part data is in a compressed state and transmit the update part data in the compressed state to the cloud storage, and cause the cloud storage to replace the updated part of the file with the update part data and to store a range including the update part data in a compressed state in the cloud storage.
