dc.description.abstract | With the progress of internet application and cloud computing, people have become increasingly accustomed to using computers to handle various issues, there are more and more data which include personal information or business secrets been stored in hard drives, flash drives, database, or even in the cloud storage. But when we have these important information stored in the computer, data corruption may be happened due to hardware failure, miss operation or so on, in order to ensure the safety of these data, data backup have become the most effective solution, and we can use the previous backup image to do data recovery when suffer data corruption, therefore, how to efficiently complete the data backup and data recovery is a serious issue and very worth to research.
However, Since each operating systems usually have dedicated file storage format, which make the market had exist more than 10 common file systems, but most of the traditional data backup solution only support mainstream file system such as FAT/NTFS/exFAT, and in fact, now we are still lack of a generic data backup and recovery solution which design for various file system. The purpose of this thesis is to satisfy these demands, the first we design a innovation data backup image format support various file system, and in order to improve the efficiency of data backup and data recovery, we further design and implement a file system used to easily store and retrieve these backup images, and we called it as “Image File System”.
