PROBLEM TO BE SOLVED: To provide a remote date control method having a relatively low network bandwidth requirement in executing a remote backup, having a relatively small space requirement for a server terminal, and capable of restoring a client terminal in a state where a backup operation is executed before selection. SOLUTION: This remote data control method includes steps for: executing a first backup operation in order to create a backup of the first content of a client data storage medium 21 in a server data storage medium 31; and executing another backup operation in order to create a backup only for the changed content of the client storage medium in the server storage medium when the change of the content of the client data storage medium since the last backup operation is executed. The backup of the changed content of the client data storage medium is stored in the server data storage medium without overwriting a backup created as the result of a previous backup operation.
