Data deduplication using CRC-seed differentiation between data and stubs

Various embodiments for differentiating between data and stubs pointing to a parent copy of deduplicated data. Undeduplicated data is stored with a checksum of an initial value. A stub pointing to the parent copy of the deduplicated data is stored with an additional checksum of a differing, addition...
