摘　　要：当发生诸如爆炸、火灾等灾难时,或者遭到恶意病毒侵害时,或者磁盘寿命终止时,布置了大量磁盘的数据系统很可能发生多个磁盘同时毁损的事件,以至于数据无法被恢复。在众多的数据备份方案中,以基于RAID6的冗余技术为基础,设计了磁盘数据恢复方案,可以对多个磁盘在确保其读写概率相同的情况下实现数据恢复。When there is a such as explosion, fire disaster, such as, or was malicious virus infringed upon, or the disk is at the end of life, Data system with a lot of disk be decorated is likely to occur the events of damaged to more disks at same time, that data can not be restored. In many data backup scheme, As the foundation based on RAID6 redundant technology, design the plan of the disk data recoveryed, To realize data recovery to multiple disk In ensure the same probability of reading and writing case.
