METHOD AND APPARATUS FOR CONTEXT AWARE BASED DATA DE-DUPLICATION

摘要

An apparatus and a method for context aware based data de-duplication is provided, the method comprising the steps of: assigning (S1) a de-duplication module by loading at least one metadata of written data and at least one metadata of written data into a metadata memory cache (40) and separating the data to be written into data chunks; counting (S2) a number of the data chunks of the data to be written and of the written data for each data segment by scanning the cached metadata in the metadata memory cache (40), the number of chunks representing a score of the data segment; and calling (S3) a data segment selection procedure providing a set of data segments based on the score of the data segment to de-duplicate the data to be written and the written data.
