摘要
随着网络技术的快速发展与网络资源的日益丰富。数据的存储量级急速增长,数据保护的重要性显得尤为重要,如何快速有效地对数据进行备份/恢复成为数据保护领域亟待解决的关键问题之一。通过对异构磁盘阵列的数据分配方法进行优化,使不同磁盘阵列间进行数据备份/恢复速率提升。提出划分异构磁盘I/O带宽方式提高磁盘数据读取速度的可行性方案,与传统的数据备份/恢复相比,在时间利用率和备份性能上都得到了很大的提高。
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.
