Relay Apparatus, System, And Method

A relay apparatus includes a receiving unit, a downloading unit, and an uploading unit. The receiving unit receives a file operation request from a client apparatus. The file operation request includes storage source information identifying a file stored in a storage area of a first server apparatus providing a cloud service with a storage location of the file, storage destination information identifying one storage location included in a storage area of a second server apparatus providing a cloud service, and operation type information instructing copy or movement of the file. The downloading unit downloads the file identified by the storage source information from the storage location identified by the storage source information. The uploading unit uploads the downloaded file to the storage area identified by the storage destination information included in the received file operation request without transmitting the downloaded file to the client apparatus.
