Abstract


As users continuously improve data backup , file archiving tool also includes in addition to the simple file copy , transform and manage files . Market mature file backup tool , the system is powerful and a wide range , such as WinRAR, WinZip , etc. , but there are several problems : the complexity of system design , lack of versatility ; WinRAR lack of management of the file set ; system maintenance difficulties ; function curing system does not support third-party extensions , high development costs ; system is the lack of openness . Data handling , file archiving tools are streaming very large amount of data to be processed , and the different functions of each of the data processing . Each data processing is a separate entity and has the same interface , information filtering , transformation and extraction , not only can achieve loose coupling between the system modules , but also enhance the versatility of the system and the input data block scalability. In this paper, consider drawing on the pipeline - filter model to establish an archiving model , each data processing as a separate entity to follow the same interface , data processing pipeline will link up to the formation of an archiving system . Specific problems exist from the currently popular backup software , the first semi-formal basis for the definition of the archive system analysis and summarized its mathematical properties , a flow -driven computing model ; then the flow -driven computing model mapping software components , to verify the feasibility and correctness of applied archiving system . Followed by detailed design, data processing and systems using pure C language implementation of a filing system . Finally, the contrast with existing backup system worry about bad summary of the deficiencies of the current system performance and system design .
