PURPOSE: A virtual storage service system based on a block device and a method thereof are provided to supply a volume snap shot backup except for redundancy data by designating a distributed node for a device volume by users. CONSTITUTION: A web server(100) receives selection information including virtual storage capacity, the number of storage nodes(410-440), a kind of the storage nodes, a distributing method, and a selected storage node for a virtual storage service from a terminal. A control center server(300) generates a virtual disk volume by referring to the selection information. The storage nodes generate the virtual disk volume according to the control of the control center server. A database(200) stores information about the storage nodes and information about the virtual disk volume.
