N2 - We study a novel distributed storage system integrated Data Centers (DCs) and satellite networks. This integrated system is expected as distributed storage system that can keep the storage service even if disasters strike because satellite is tolerant to link disruption caused by disasters. In this paper, we focus on data distribution method in the integrated system, and assume an erasure coding and a simple replication as data distribution method. We evaluate the storage volume and transmission time on each method which are required to restore lost data when some DCs are damaged by disasters. The storage volume of the erasure coding becomes lower than that of the replication while the transmission time becomes higher. A data transfer method is proposed in this paper to shorten the transmission time of the erasure coding. The proposed method can reduce the transmission volume on downlink communication by using network coding technologies. The numerical results show that the proposed method can restore the lost data in less time.
