The operation of modern enterprises are more than depended on information technology, any lose of information data may lead to immeasurable damage to corporations. How to response large disaster is more important to all companies. At the present time, It is unique solution that the remote disaster recovery system is built. Backup and recovery operation of crucial data have become an important part of systematic daily operation maintenance.Disaster Tolerance System (DTS) of XX project has its data-backup centre in remote area far from the local place,the data is backup to remote data sit via Internet. And the local high availability cluster computer system is used to improving the availability. Data backup in different areas is the core technology of disaster-prevention system. It plays an important role in consistency and reliability of data, which also affects system's expansibility. By valid data copy, transmitted data in local area and other city can be synchronous which can ensure that disaster-prevention centre in long range can take charge of operation promptly when local system is in trouble.User Interface Subsystem, State Analyze Subsystem, Policy Manage Subsystem, Take-over and Concur Subsystem, Data Recovery Subsystem are composed the Disaster Tolerance System of XX project. In the exploitation of Disaster Tolerance System (DTS) of XX project, an approach of data backup and data recovery based of Linux platform has been put forward, this paper also designs the Data Recovery Subsystem in detail, and proposes data backup approach based on mirroring table and triggers best serve the turn of XX project.This papers describes the background of this task and its origin, the states of application and investigation, states the importance of Disaster Tolerance System (DTS), researches the scheme of the DTS in XX project , does detailed design on Data Recovery Subsystem of DTS in XX project, designs a program of data backup server the turn of DTS in XX project. The actual detections show that the approach this paper proposed has very important effect in the things like that it guaranties that XX project system offers service promptly and continuously, achieves backup and recovery of data in XX project, and also provides it's...
