DATA DEDUPLICATION USING CRC-SEED DIFFERENTIATION BETWEEN DATA AND STUBS |
| 摘要 |
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, additional initial value. |
