A Data Backup Method Based on File System Filter Driver

As an important means of information security, data backup technology has attained increasing attention. This paper proposes a data backup method based on file system filter driver. It monitors various operated events of application program through file system filter driver and do incremental backup by recorded events. The related experiment verified that the method reduces the file backup redundancy, improves the backup efficiency, and to the right to monitor the file attributes, name changes and other events. The method has broad application prospect in actual data backup system.
