In order to improve the efficiency of file backup,a method of event-based file backup is proposed.The method is real-time monitoring the file through the file system filter driver,to capture the success of operation made by monitored file,and write the infor-mation into the log.According to the log records to classify the file,then backup them with corresponding strategy,file monitoring,backup queue generation and difference set reconstruct methods are given.The experimental results indicate that,compared with Rsync the method can effectively reduce the amount of file backup calculation and decrease the amount of network traffic,significantly improve the efficiency of file backup.
