How to guarantee the reliability of data in cloud storage system is a hot issue in cloud computing field. Replica backup technology is an important means to guarantee data reliability, but it has the problems of large storage space and low storage efficiency. The erasure code can provide optimized data redundancy to prevent data loss, proper use of erasure codes can improve the efficiency of space utilization and obtain better data protection effect, has been widely used in communication. In this paper, the erasure code is introduced into the cloud storage system instead of the copy backup strategy to improve the performance of the cloud storage system. Experimental results show that the proposed scheme can effectively improve the data reliability and space utilization.
