摘　　要：该文设计并实现了一种分布式多策略数据库容灾系统,该系统提供了多种备份和恢复策略,能快速有效地备份和恢复用户数据。当主数据库发生灾难时,能切换备用数据库为主数据库继续对外提供服务,保证业务的连续性。在主数据库失控"后,能销毁数据库上的数据,防止重要数据外泄。A Distributed and multi-strategy disaster tolerant System for database system has been presented. This system proves the varied strategy of backup and pecovery, and it can backup and recover the data of user availably and fast. After disaster happens, it will switch back-database main-database, and then provide service for users unceasingly. And it well ensure the continuity of service .When the main-database is ＂out or control＂, this system can destroy the data which is stored in the databases and can prevent the important date from leaking out.
