Research of Data Redundancy Strategy in Cloud Storage

With the extensive application of cloud storage,the method of redundancy is generally used to ensure the integrity and availability of data.This paper firstly introduces the data storage method in cloud storage,next,studies some data redundancy strategies in cloud storage,analyzes the advantage,disadvantage and scope of application of these strategies partly,and finally makes a quantitative analysis of these data redundancy strategies in availability of data.The authors hope this paper is helpful to one who wants to select right data redundancy strategy.
