Abstract
A file deduplication processing system is provided. The system deduplicates raw files to generate deduplicated vault files and a descriptor indicating a storage location of each data chunk in the vault files corresponding to the raw files. When receiving a writing request of a write data, the system finds at least one data chunk including old data corresponding to the write data according to the descriptor, loads and recovers the data chunk whose boundary is not overlapped with a boundary of the write data in the vault file comprising the old data corresponding to the write data so as to generate an update data by incorporating the recovered data chunk and the write data, deduplicates the update data to generate a new vault file and stores the same in the chunk store, and updates a content corresponding to each data chunk in the descriptor.
