The Backup Disaster Recovery System Of Guangshen Public Transport

The railway sector and is closely related to people's livelihood, but also dependent on information systems is very high, in the event of malfunctions and accidents can cause serious social impact and consequences. Disaster recovery system for the building of the railway company's information systems to establish a comprehensive information security system for the stability of the railway transport business to provide free security guarantees; At present, railway ticket booking system and available for sale, transport chain of command scheduling, passenger and freight rail Marketing systems has become increasingly dependent on computer systems, information systems will lead to the interruption of rail transport throughout the production is seriously affected, the information system of disaster recovery is essential.SYBASE the ASE database can be a dual system of on-line, real-time security Backup, and by all the mainstream hardware / platform vendors (IBM, HP, SUN, NCR, DEC, NT, etc.) support, and is widely used in the key Industry applications.This article elaborated on the principle of disaster recovery, as well as the application of the current mainstream technology, and various classifications theories of technical knowledge. And describes the application of key technologies disaster recovery development for Disaster Recovery System to make the necessary data replication technology, disaster detection technology and application switching technology more in-depth research, combined with the practical application of the project, as well as the characteristics of their own SYBASE Provided some very good command of the instrument, such as: BACKUP SERVER and BCP, the former database to log all the data or as a backup to a file, which can easily form a data backup and recovery. Combined with the practical application of the work, made use of the Sybase back-up tool for data backup and recovery program.In this paper, identified by the disaster recovery system to achieve the specific technology used.
