| Abstract: | A Distributed and multi-strategy disaster tolerant system for database system has been presented. This system provides the varied strategy of backup and recovery, and it can backup and recover the data of user availably and fast. After the disaster happens, it will switch back-database as the main-database, and then provide service for users unceasingly. And it will ensure the continuity of service. When the main-database is "out of control", this system can destroy the data which is stored in the databases and can prevent the important data from leaking out. |
