设计并实现了一种远程容灾系统。通过实时监控本地存储服务器上的数据变化,并将变化数据通过Intemet发送到远程灾备服务器来实现数据的远程备份,通过将远程备份数据写回到本地存储服务器来实现灾难恢复,生产服务器的容灾数据存储于本地存储服务器中,通过iSCSI技术访问。该系统提供了多种数据同步与恢复策略,并提供了图形化Web配置管理平台,支持多种操作系统。
A remote disaster tolerant system is designed and implemented. The remote backup is implemented by monitoring local datachanges and sending changed data to remote backup server on the Intemet, the disaster recovery is implemented by writing the backup data to local storage server. Production server' s disaster recovery data are saved in local storage server, it accesses the data via iSCSI technology. System provides several data synchronization and recovery strategies, a graphical web configuration management platform, and supports various operating systems.
