PURPOSE: A data dualizing method for a block storage service of cloud computing is provided to improve performance by connecting a volume of a storage server close to a physical server in which an instance is executed. CONSTITUTION: If a terminal requests a computer resource, a server rack supports an instance(S100). If the terminal requests volume generation by using the instance, an active volume is generated in a storage server included in the server rack(S200). If the terminal requests volume dualization, a standby volume is generated in a storage server included in another server rack and connected with the active volume to be provided(S300). The active volume, used by the instance of the server rack included in the storage server in which an error occurs, is extracted(S400).
