Research On The Data Recovery Technology Based On Backup

With the development of computer, the storage and reliability of data is increasingly important. More attention is paid to hardware memorizer, the main carrier of storing data. Therefore, the problems such as how to make backup before losing hardware data and how to quickly and completely recover data after losing it with the purpose of reducing the users'loss as much as possible should be immediately solved. The research is carried out in the following aspects.Firstly, the basic theoretical knowledge about data recovery technology and backup technology is introduced in details.Secondly, the failure causes of partition table are analyzed, the concept of self-backup is imported and the access to backup file is achieved by means of self-link file and then the data recovery scheme in sensitive area is proposed.Thirdly, the frequent failure from common removable storage medium is analyzed in details and corresponding data recovery methods are put forward. Especially, the rules of piloting sections storage position are summarized. Later, the present self-backup strategy is improved and the self-backup scheme verifying before backup is set forth.Finally, the functional module used by various data recovery software is fully analyzed. The data recovery scheme of quick positioning is proposed through combining all factors related to data recovery for the sake of too long searching time in the process of using the software. The achievement process of the scheme is shown by analyzing some instances...
