Design And Implementation Of Disaster Recovery And Backup In Big Data Center

With the arrival of the big data era and the rapid development of e-government,the data produced by the government is growing rapidly,and the distributed storage types are changing to centralized storage.While the massive data brings convenience to the government office and the people's livelihood service,the data security becomes particularly important,and the disaster recovery backup shows his necessity.According to the Yangzhou municipal government data resources center as the main design,according to the present situation of government data center,and analyzes the necessity of disaster recovery,disaster recovery and the introduction of existing core technology choice,given the overall construction plan,the project implementation schedule,the estimate of the fund etc..(1)summarize and analyze the status quo of Yangzhou municipal government data resource center,and put forward the necessity and feasibility of establishing disaster recovery backup center.The work of the government in the development of information technology change rapidly in the background,although the risk of government cloud computing center did not collapse,but a large number of data loss can lead to paralysis of the people's livelihood of many,the work of the government will be unable to expand.(2)disaster recovery center room refers to a prescribed distance within the region,the establishment of room to check the switch function and health status of two or several sets of the same function,business center room system accident disasters or other disasters such as stop running,the service system can quickly switch to the backup center room.In order to ensure the normal operation of the business.The disaster recovery system mainly used for serious disaster disposal irresistible to the entire production center,providing rapid recovery production center operations,to achieve high availability of business systems.(3)give the overall construction plan,including construction regulations,tactics,direction,essence and so on.The construction of the Yangzhou municipal government information resources management center backup and security system is the information security system is an important part of the strategic plan and the main development trend,can adapt to information technology;but the need to follow the principle of e-government disaster recovery system(4)through the comprehensive analysis,put forward suitable for Yangzhou data resource management center and disaster recovery mode construction scheme.The cloud computing center is the main production center responsible for the normal operation of all application systems.In the event of a disaster,can in the city disaster recovery center in time to restore all the important business and ensure normal operation.The Bureau commissioned the Xuzhou remote disaster recovery center to carry out important data backup,to ensure that the core data of disaster stricken business systems will not be lost.(5)proposed the software and hardware selection and design of disaster recovery construction,through the actual business system of Yangzhou cloud computing center of the use of specific recommendations of hardware and software,which contains the design of hardware and software integration system,database backup,cloud computing platform system of the city and remote disaster recovery.(6)for replication and "cloud" data UPS,GoldenGate computer room precision air conditioning system was tested and verified by Dangxiang synchronous test of GodenGate data replication technology,verification of unidirectional synchronous DML in actual operation can be realized and reliability;for sampling test UPS,precision air conditioning system,verify "infrastructure and environment Huayun room" as standard municipal government with disaster recovery room.
