The Design Of Backup System Based On Cloud Computing

With the widespread use of the Internet,all walks of life have established their own portals and data centers.These important data are often the lifeblood of the company and determine the future development of the company.The development of informatization,the increase of business volume,and the increase of data flow have made the data of enterprises more and more centralized,and the threat of data loss has become more concentrated and increased.In recent years,companies that have declined due to data loss and bankruptcy are not uncommon.The loss caused by data loss is huge and even immeasurable.More and more enterprises are considering to back up data.Domestic disaster recovery backup policies have also been issued,requiring government departments to ensure the security and integrity of data,and to take disaster recovery backup measures for important data when necessary.Based on the specific needs of a government user,this paper analyzes and discusses the disaster recovery backup scheme applicable to the user.After the requirements are understood,the technical route is discussed,and the networking scheme is compared,the disaster recovery backup scheme of the two centers is formed.According to the user's data,business and other specific conditions,select the appropriate hardware equipment and backup software to implement the disaster recovery backup in the field,the effect is good,and the user's expectations are met.The work of this paper is mainly divided into the following aspects:(1)Analyze the specific needs of users,study the relevant regulations and guidance for the disaster recovery backup of the national policy,and determine the construction level of the user's disaster recovery backup system by comparing the levels of the disaster recovery system.Summarize the various implementation methods of disaster tolerance and determine the research direction of this program.(2)Summarize the advantages of cloud computing,combine the development of Unicom in cloud computing,compare and analyze the advantages of cloud computing for disaster recovery,and determine the disaster recovery mode of private cloud based on the advantages and disadvantages of different types of cloud computing.Research on the application of storage key technologies in disaster recovery backup,and integrate horizontal expansion,load balancing,and snapshot technologies into the underlying disaster recovery storage.Analyze the advantages and disadvantages of asynchronous disaster recovery and synchronous disaster recovery,compare the conditions and effects of disaster recovery and remote disaster recovery in the same city,and develop the disaster recovery networking mode of the two centers.(3)Communicate with users,further calculate the storage capacity and business volume of the user system,determine the data capacity of 70 TB per center,inspect the environment of Unicom's computer room,and set the IDC machine room of Silicon Valley Street as the center of the same city,and set the computer room of Baishan.It is a disaster recovery center.Organize equipment procurement and on-site implementation,and verify the construction effect of the program through drill verification.The results show that the disaster recovery mode of the three centers in the two places can ensure the integrity of the data and ensure the continuity of the service in different scenarios.It has good stability compared with the single city live and remote storage disaster recovery.Sexual and catastrophic,the loss of data is the smallest compared to other models,meets the expected standards of program development,meets the requirements of users,achieves the desired results,and is satisfied by users.The main contributions of this paper are as follows:(1)Fully combine the advantages of Unicom in cloud computing,and integrate disaster recovery backup and cloud computing perfectly.On one hand,it solves the business continuity and data integrity requirements of users,and on the other hand drives the cloud computing business.The income has established the professional image of Unicom and enhanced its brand awareness.(2)The disaster recovery backup mode of the three centers in the two places has broken the single mode of double-lived or remote disaster recovery in the same city,and combined the two disaster recovery modes to ensure the double-lived service level that can be realized in the same city.Disaster tolerance has solved the problem of data loss if there is a local geological disaster.(3)The scheme has good reproducibility,can be flexibly adjusted according to different users,and can be deployed quickly,and does not involve professionalism in different business fields.It is conducive to Unicom's deployment in various industries and cooperation,which is the first sight.Customer,a good solution for breaking ice.Can bring good returns to the company.
