CLOUD STORAGE SERVER AND SYSTEM BY USE OF VIRTUAL NAS AND METHOD THEREOF

摘要

PURPOSE: A cloud storage server using a virtual NAS, a system thereof, and a method thereof are provided to generate a virtual NAS(Network Attached Storage) by a cloud hosting service, thereby enabling a user to back data up by data synchronization between a NAS device in an SMB(Small Medium Business) and a virtual NAS device of a cloud hosting server. CONSTITUTION: A NAS device(114,118,122) is installed in an internal network. The NAS device stores file data which are made by an internal terminal. A cloud storage server(106) is connected to the NAS device and a communication network. The cloud storage server generates virtual NAS(114-1,118-1,122-1)s wherein the NAS device and the virtual NASs synchronize and back up data. The cloud storage server copies file data stored in the NAS device through the virtual NAS and stores the backup data.
