Can Zhang · Jisuanji gongcheng · 2008
A method of Fast Differential Backup(FDB) is proposed and implemented,by which the renaming problem that troubles industry for a long time is solved. Through applying the policies of snapshot management,file fast filtration,differential calculation and differential remote playback,the approach is put into practice. By experimental analysis,this method is proved to be able to reduce the overhead of remote storage server effectively,save network resource,improve the utilization rate of system resources,and reduce the customers' data security risk and cost of running the backup system.
