Abstract:
1. A method for data deduplication, comprising: acquiring meta data and data chunks corresponding to at least one original data object, wherein the data chunks are generated by performing a deduplication; combining the acquired data chunks into a new data object; performing an additional deduplication on the new data object to generate new meta data and new data chunks corresponding to the new data object; 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; and using the new meta data and the new data chunks corresponding to the new data object as meta data and data chunks corresponding to another original data object, iterating through the combining of the data chunks into another new data object and the performing of the additional deduplication until new data chunks obtained in a present iteration from the additional deduplication are identical to data chunks obtained from a previous iteration.
