DEVICE AND METHOD FOR ELIMINATING FILE DUPLICATION IN A DISTRIBUTED STORAGE SYSTEM

摘要

The present invention relates to a device and method for eliminating file duplication in a distributed storage system. The device and method for eliminating file duplication in a distributed storage system according to the present invention involve calculating chunk-specific hash values for active files, calculating secondary hash values by adding the chunk-specifically calculated hash values, checking for file duplication by using the chunk-specific hash values and secondary hash values, and then eliminating duplicate files in the results of the check.
