| Abstract: | This article summarized the common faults of EMIS field database, analyzed the advantages and disadvantages of the existing database backup strategy. According to the actual usage of the EMIS field database, the article optimized and studied the existing database backup scheme in-depth, made a set of database backup scheme which was easy to operate and high availability. The scheme was implemented and applied to all of the EMU depots for improving the integrity and continuity of database recovery, ensuring the security and stability of information system data. |
