The Study And The Realization Of Data Remote Backup And Its Recovery Technology

With the high development of information technology in society,the computer has played a more and more important role in the country,enterprises as well as the personal field.As the most important component in the informational system, data has obtained high attention from the public for its security.The wide-spread usage and fast development of the web has made the delivery and usage of the data much more convenient,but personal mistakes,the computer virus,the light-off may lead to the loss of certain data,thus data backup is increasingly critical.First of all,the article discusses the meaning of data recovery and data recovery at home and abroad to develop the field of the status,shows the significance of the study subjects,the overall framework and the modules in this subject.Based on the detailed analysis of the demand,the thesis explored deeply into the technological characters as well as the application advantages of the C/S structure,and devised the general structure of the system on the basis of the C/S structure.Besides,the theoretical storage mechanisms under the current two popular file systems of Windows:FAT32 and NTFS have also been analyzed in details.What's more,the thesis has also touched upon the explorative concepts using groupware,and made researches of the data structure and their functions of the modules designed under the direction of the theory of serving the objective users like the inspecting module for file checking,the data security module, the management module of the data delivery on the web,the data backup module.At the same time,the respective structure flow of each module has also been examined fully. Finally,the neat and friendly interface for the users has also been elaborately designed, which greatly promotes the feasibility of the thesis and the fine interactive functions with the users.The content of the thesis can be divided mainly into four parts:In the first chapter, the file storage theories of the two popular Windows file systems have been introduced, with the file backup theories illustrated.In the second chapter,with the help of the Hook technology and the rules and regulations of self-definition,the instant inspection on the computer file data has been realized to secure the integrality of the data.The data security has been greatly improved by the use of the mainstream encryption technology and the self-definition arithmetic interface.The synchronous delivery of the file data based on the Sockets has been realized,which is stable and less loaded for the web.In the third chapter,the backup of the file partition table under the systems of FAT32 and NTFS has been illustrated from the practical angle.In the fourth chapter,the usage of the system has been briefly introduced,with some improving suggestions put forward.
