A replication system includes: N (>=3) storage devices; and N nodes, connected to a host via a 1st network and connected to the N number of storage devices via a 2nd network, each to receive a request for accessing a storage device associated with itself and to have an access with a content in response to the received access request to the storage device, wherein when a node receives a write request of data from the host, each of M nodes (1<M<N) including the node stores the data in the storage device associated with itself, and if first data in a first storage device cannot be read out, the first data stored in another storage device is stored into a second storage device not stored with the first data by transmitting the first data via the second network.
