Abstract: This article analyzed the demand of backup for the database of station system and application program, studied on the basic framework and features of the general parallel file system(GPFS), added the new host to the existing GPFS cluster, implemented the real-time concurrency access to shared storage in a cluster. It was solved the problem of third party backup for the production data of the station system and application crash recovery, achieved the purpose of integrating backup resources, avoiding single point, hidden danger, saving backup cost, further ensured the safety production of railway information.
