To solve the problem of the low efficiency of Multi-duplicate under the environment of Cloud Storage, this paper proposed a high-efficiency strategy of data safety storage. The strategy adopts the parallel processing ideology and designed the high-efficiency algorithm of the data parallel storage. The algorithm designed to transponder the request coming from the user to many workers, which write user data to the given duplicate server. The strategy is designed as the integrity coordination and the parallel processing mode, which is to say that all the workers are handled by the manager, and every worker is served to the given duplicate server. The manager handles the mutual actions with the users, and all the workers are transparent to the users. Thus the design mode does not increase the complexity for users to use the cloud storage. The experimental data indicates that the strategy this paper designed can decrease the time spoilage under the condition of Multi-duplicate and can ensure that the efficient of the read and write to the cloud not lower than the single-duplicate. The scheme is used for cloud storage environment and efficient data storage is feasible and effective.
