A High-efficiency Differential File Recovery Method
For the problem of low efficiency and slow speed in file recovery area, a fast differential file recovery method was proposed . The remote backup center keeps the reverse difference set and the latest full backup file,to achieve the recovery file, the reverse differential files are used to reconstruct the file we need by time reversal. Experiment results show that this method significantly reduces the reconstruction time, and improves the efficiency of file recovery evidently in comparison with the traditional differential recovery method.
