摘要
该文提出并实现了一种基于Internet的数据级容灾系统。采用基于数据块存储的远程数据复制技术,将本地服务器上的数据通过网络备份到远程数据库中,当发生灾难时,利用多种恢复策略手段,实现数据恢复,并通过一致性检测手段确保主备数据的一致完整性,实现了一个能够为广大用户提供备份及恢复服务的容灾平台。
A data level disaster tolerant system based on internet have been designed and implemented in this paper.Using the data block restores technology for data replication,made the local servers data backup to the remote database.When the disaster happened,it will use variable recovery strategy measures to resume the data.Data consistent check technology ensures the data consistency between the primary and backup system.Afford a flat which can support the data backup and recovery come true for variable users.
