The Design And Implement Of Cloud Disaster Backup System For The Data Of Local Tax Bureau

As an important national functional department,the tax system has high requirement for the safety and reliability of data.With the information progress becoming greater and greater,the demand of data disaster backup is increasing.The traditional data disaster backup mechanism can not meet the new demand of real-time and reliability in architecture and function.The cloud data disaster backup system can meet the demands of real-time,reliability and scale.This thesis design and develop a system of cloud data disaster backup for tax system.The main work of the thesis include:1.Combed and analyzed the tax business,collected the requirement of data disaster backup of tax system.According to the exist research and application,analyzed the problem of disaster backup in tax system.2.Researched the related technology of data disaster backup mechanism,analyzed the feasibility of cloud data disaster backup in tax system.Then focused on two key points of cloud storage and cloud safety.3.Analyzed the detail requirement of tax data disaster backup,especially the requirement of cloud data disaster backup.4.Designed the mechanism of cloud storage,including the data model and handle,application architecture and function.5.Designed the safety mechanism for cloud data disaster backup system,including the data encoding,multistage confidence mechanism,access control and safety audit.In general,the thesis present the method of cloud tax data disaster backup,which can be developed to more similar area.
