Research of File Backup Method Based on Double Cache and Minifilter Driver

摘要

Aiming at the shortage of the low efficiency of file backup, large amount of data, highly occupancy rate network resource, Put forward a file backup method based on double cache and mini-filter driver. Method uses Cache Manager creates two caches in kernel model, at the same time combined with real-time monitoring of mini-filter driver to the file of operation information, turning it into a log classification records that procedures easily identify, and processing the file backup in cache, so as to achieve fast and efficient file backup. Experimental results show that this method can effectively reduce the disk reading and writing frequently, reducing the network resource occupancy rate when carry on the file backup, substantially increasing the speed of file backup.
