Handling rewrites in deduplication systems using data parsers

摘要

Methods, computer systems, and computer program products for deduplicating data are provided. Data is parsed to identify portions of metadata within the data. The data and identified portions of metadata are processed by a deduplication engine to be storable in a single repository. The deduplication engine is adapted for deduplicating the data without at least one of deduplicating and indexing the identified portions of metadata.
