设计并实现了一种远程备份/恢复容灾系统——DRC。该系统采用本地灾备网关作为中间介质,实现本地高速镜像;通过镜像远程设备到本地,实现远程数据备份;使用实时状态监控和系统重建技术完成系统的自动恢复,以达到容灾的目的。另外,该系统支持多种操作系统和数据库;远程备份和恢复工作采取用户控制和系统自动实现两种方式;该系统还提供了配置管理工具,便利远程管理。
A remote backup/recovery disaster tolerable system referred to DRC has been presented. The system uses local gateway as medium to mirror local data in high speed ; backups data in the way of imaging remote devices ; recovers data automatically by real-time system monitoring and system reconstruction, and it supports many operating systems and databases, The backup and recovery can be controlled either by users, or by the system itself, It provides a management tool for the ease of remote control of the system.
