摘要:
A relay server includes a storage configured to store first access right information of a first cloud storage service to which a first user is subscribed and second access right information of a second cloud storage service to which a second user is subscribed. The relay server further includes a communication interface configured to request, from the first cloud storage service, first data that is stored in the first cloud storage service, based on the first access right information, and receive the requested first data from the first cloud storage. The relay server further includes a controller configured to control the communication interface to store the received first data in the second cloud storage service, based on the second access right information.
