Fragments File Recovery System Based On Disk Access Log

With the rapid development of global informationization,information has become an important resource of social development,on the resources to carry out the global competition.Priceless "" computer has a price,data is the information age to recognition of the importance of data,the development of the information society makes information resources possession.Therefore,data security has become one of the hot issues people care about,one of the important research topic is the data recovery.Data recovery research in China starts late,but development soon,now more authority is a delegate with Mr Dai Shijian military institute and represented by Mr TuYanHui data recovery company,and some data recovery software,such as doctor PTD partition table.With the rapid growth of data quantity,there are more and more big file data.The data in the modern operating system file management,mainly adopts discrete storage method,therefore,these large file data will produce a lot of debris in the disk storage.Traditional data recovery technology for fragment file recovery effect is not very well,often appear to restore the data will not be able to use,such problems as incomplete and prolonged recovery.Therefore,how to solve the efficient data recovery of fragmented files,become an important research in the field of data recovery problem.In view of the problems existing in the traditional data recovery technology,and data recovery is very important for today's information society is,so I study in this thesis a for fragment file recovery method of high speed and success rate of recovery,to meet the demand of data security in today's massive amounts of information society.In this thesis research disk storage technology,on the basis of the structure and the file system is put forward based on the log file analysis of missing data for rapid and high success rate of recovery method,can be in the loss of data,through the lost before analyzing log files on disk,quickly locate file data area,which will be lost quickly and data recovery.The recovery of this method for debris file will greatly improve the success rate and speed of the recovery.This thesis has the following innovation and features,first of all,the paper puts forward a kind of innovation for fragment file recovery method,can guarantee the fast and high success rate of fragment file recovery.Secondly,this paper to fragment file recovery does not rely on the analysis of the file structure,saves a lot of analysis of the process of file structure,improve the efficiency of data recovery.In addition,this thesis has carried on the cloud to log records also backup,strengthening the reliability of the system.Inspection and testing experiment of this paper,illustrate the validity of the proposed new data recovery method,and data recovery efficiency.
