A Study On Centralization Of Backup For Disaster Recovery Basing On Region-Centralize Large System

This article is the research about centralization of backup for disaster recoveryin a long distance for the certain financial market. Considering the characteristic andpresent state of the enterprise, the enterprise decides to establish a centralization ofbackup system for disaster recovery to protect the data of thirty one provinces.Analyzing the present technology of backup for disaster recovery, thecentralization of backup for disaster recovery that is a long-distance mode byarchivelog style of the database meets the requirement, validates the feasibility byexperiments. At the same time, the enterprise further clarifies the requirement basedon existing system environment and test data, the system is designed considering notto influence the existing system, to centralize the backup for disaster recovery, toexpedite the transfer speed via transfer software, to reduce the couple of the producecenter and the disaster recovery, to avoid the transfer difficulty caused by theproduction burden so as to arouse the problem of the data base source.The program is made to the requirements to satisfy the disaster recovery backupand design a system transfer mode to guarantee the consistence of the main and thebackup database while reduce the couple at the same time, and expedite the transferspeed by compressing, splitting and parallel communication, validate the data byverifying. The program is approved to have more advantages in long-distancetransfer and avoidance of man-made demolish than the pure database level disasterrecovery backup.The conclusion is a summary of the research which the author participates andto present some opinions relating to the research program. The author takes part inthe program design and test, and the research and development, and commits thea(?)rangement of the testing areas.
