The existing evaluation is not accurate to redundant storage strategies of structured peer-to-peer(P2P) networks. Hence, introduced a new evaluation data invulnerability, which was irrelative about the node availability. After that, this dissertation modeled the data invulnerability through three perspectives: replication, blocking replication, blocking replication based on a fixed central point. Based on the proposed data invulnerability, this paper proposed a dynamic center-based data storage (DCDS) strategy. Simulation results show that the DCDS strategy can increase the number of data in networks efficiently on the premise of node failure continuously.
