Method and system for data deduplication

A computer program product for data deduplication, the computer program product comprising:

• a computer-readable medium having program code embodied therein, the computer readable program code, when executed by at least one processor of a computer, is configured to perform:
• 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;
• 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.

A data deduplication system, comprising:

• at least one processor;
• and
• a storage device coupled to the at least one processor, wherein the storage device stores program code, and wherein the processor is configured to execute the program to perform operations, wherein the operations comprise:
• 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;
• 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.
