LOOKUP-BASED DATA BLOCK ALIGNMENT FOR DATA DEDUPLICATION |
| 摘要 |
Calculating fingerprints for each one of a multiplicity of alignment combinations of fixed-size deduplication data blocks and comparing each of the fingerprints to stored deduplicated data fingerprints in a lookup database for determining a preferred deduplication data block alignment. A deduplication data block comprises each of the fixed-size deduplication data blocks. |

1. A method for lookup-based data block alignment for data deduplication using a processor device in a computing environment, the method comprising:
calculating fingerprints for each one of a plurality of alignment combinations of fixed-size deduplication data blocks and comparing each of the fingerprints to stored deduplicated data fingerprints in a lookup database for determining a preferred deduplication data block alignment. |
