Research On Data Backup And Recovery System For Electric Power Industry

Information has become an important asset of the all kinds of organization of whole society such as state,enterprise and individual.In the network application environment,many factors may result in data loss,data damage and data destruction,which will bring huge losses to the people's daily life and even the country's economic development.Power industry is the basic industry of national economy,the data of power industry are very important.State Grid Shandong Electric Power Company has made the corresponding protection to the information system.However,with the development of cloud computing,IT infrastructure has changed dramatically.In the new situation,this thesis studies the data backup and recovery of State Grid Shandong Electric Power Company.In this thesis,the needs of disaster center,personal data backup and recovery,virtualization based fast recovery will be researched.The main work of this thesis are:1.Research on the information system of State Grid Shandong Electric Power Company.The related indicators of disaster recovery center are given including IT infrastructure,recovery level and continuity of business.The information systems are classified according to data importance level,application importance level,loss of data corruption,loss of application interruption,etc.In accordance with the protection level and the cost of construction and operation of disaster recovery system,the protection and recovery policy is designed.The policy includes data protection policy,application protection policy,recovery policy,check point policy and so on.With the policy applied,the information systems are protected effectively and the interruption of the power production is minimized.At the same time,according to the importance of the system,different backup/recovery technology and backup strategy are chosen and applied.2.The personal data backup and recovery system for private cloud desktop environment are designed and implemented.This thesis designs a method to filter the changes according to the rules.The changed file is classified according to the source of the change,file type,process type and so on.The files that need to be backed up are filtered out.The relationship between the files and the backup files are calculated.The necessary files are backed up and recovered in the proper time.Therefore,this method can effectively reduce unnecessary backup files,protect the files with backup value and improve the backup efficiency.3.A fast recovery system based on virtualization technology is designed and implemented.The system architecture,fast recovery process,backup chain and recovery chain are designed.By building specific experimental environment,this method can improve the backup efficiency and reduce the difficulty of verifying backup files.
