DEDUPLICATION METHOD AND DEDUPLICATION SYSTEM USING DATA ASSOCIATION INFORMATION

摘要

A deduplication method using data association information includes extracting information about a target file and at least one reference file associated with the target file as association information before duplication determination is performed. The at least one reference file is identified by the association information as a comparison target set for comparison when the duplication determination of the target file is performed. The duplication determination is performed with the target file with respect to the at least one reference file in the selected comparison target set.

1. A method for deduplication in a memory system using data association information, comprising:
extracting information about a target file and at least one reference file associated with the target file as association information before duplication determination is performed; identifying the at least one reference file using at least the association information as a comparison target set for comparison at substantially the same time as the duplication determination of the target file is performed; and performing the duplication determination with the target file with respect to the at least one reference file in the selected comparison target set.
