Abstract

The invention discloses a system to remove redundant file in file storing system, which is characterized by the following: comprising sea quantity memory system; constructing with the memory server module and index server module; also comprising pre-treating module, quick storing module and removing repeat server module; getting file MD5 value and file size with the pre-treating module; proceeding file quoting number statistic with the quick storing module; deleting repeated file when the file quoting number reach intended value with the removing repeat server module; connecting the index server module, the storing server module and the pre-treating module consecutively; connecting the quick access module, index server module, storing server module and the pre-treating module to the removing repeat server module. This invention also discloses a corresponding method to remove redundant file in accessing system. This invention can control carrying cost effectively.

Description

technical field [0001] The invention relates to the field of data processing, more specifically, to a system and method for quickly eliminating redundant files in a file storage system. Background technique [0002] In any large-scale storage system, there are a large number of redundant files. For example, there are often multiple copies of a file in the local hard disk of a personal computer. Many of these copies are due to operational errors or user forgetting. caused by copying. However, in a system shared by many people, due to poor sharing between users, the redundancy of files is very high. With the rise of network hard drives, many Internet companies provide users with many redundant files in the network hard drives. In addition, there are also a large number of repeated web pages and files in web search engines. For a file storage system, the main cost is the equipment cost, and eliminating redundant files in the system can greatly save equipment costs, and elimi...
