With the rapid development of network technology and increasingly network resources,the magnitude of data storage is rose rapidly,so the data protection becomes vital to maintain business continuity,How to backup/restore data efficiently and effectively is one of the most urgent questions today.Optimizing the data assignment method of heterogeneous disk array to increase the rate of different disk array backup/restore.A feasible method of dividing heterogeneous disk I/O bandwidth to improve data read speed is proposed,which can significantly decrease backup time and storage cost compared with traditional data backup/restore method.
