Abstract
The present disclosure discloses a method and system for data deduplication. The method comprises: acquiring meta data and multiple data chunks corresponding to at least one original data object, which are generated by using a data deduplication method; combining the acquired multiple data chunks into a new data object; performing deduplication on the new data object to generate new meta data and new data chunks corresponding to the new data object; and storing the meta data corresponding to the at least one original data object, the new meta data corresponding to the new data object, and the new data chunks. The method and system can further improve deduplication ratio, lower data storage amount, and save costs.
