Abstract
A technique for performing deduplication on compressed data in a file system operates inline with storage requests, e.g., prior to writing compressed data specified in those storage requests to persistent file system structures. As requests to write data arrive, the file system compares those data with data already stored in the file system. If a match is found, metadata structures are written but compression and file system storage of the newly arrived data is avoided.
