摘要
基于网络层存储虚拟化,结合(n,m)数据分散技术,提出了一种适于分散部署的多数据中心、多容灾备份中心之间的分布式数据容灾保护方案。该方案通过对容灾数据的拆分与整合来实现分布式保护,在保证容灾数据灾难恢复能力的基础上,既减少了存储空间的占用率,又增强了容灾数据的安全性。
Based on the storage virtualization in the network layer,and combined with the(n,m) data dispersal technology,this paper proposes a project about the distributed data disaster-tolerance protection,which is adaptive to the multi-data center and multi-backup center.Through encoding-dispersing and decoding-integrating,we implement the distributed data protection.This project saved storage space,and strengthened the safety of the data,without compromising the basic ability of disaster recovery.
