DEDUPLICATION IN DISTRIBUTED FILE SYSTEMS |
| 摘要 |
Deduplication in a distributed file system is described. Key classes are determined from a set of potential keys, the potential keys used to represent file content stored by the file system. Control of the key classes is apportioned among index nodes of the file system. Nodes in the file system, during deduplication of data chunks of the file content, generate keys calculated from the data chunks. The keys are distributed among the index nodes based on relations between the keys and the key classes controlled by the index nodes. |

1. A method of deduplication in a distributed file system, comprising:
determining key classes from a set of potential keys, the potential keys used to represent file content stored by the file system; apportioning control of the key classes among index nodes of the file system; nodes in the file system, during deduplication of data chunks of the file content, generating keys calculated from the data chunks; and distributing the keys among the index nodes based on relations between the keys and the key classes controlled by the index nodes. |
