Patent ID: 8560716

Claim:
A method for processing data comprising: receiving a datastream; analyzing the datastream for chunk headers, data chunks and chunk maps; determining from the chunk headers a first data manipulation technique of a data chunk, an unmanipulated data chunk size, and a manipulated data chunk size, wherein the first data manipulation technique includes at least one from a group comprising data compression, data deduplication, and data encryption; wherein the chunk headers indicate a size of the data chunks after the first data manipulation technique has been applied to the data chunks; and wherein the chunk headers indicate a false size of the data chunks that comprises a raw data size to a backup application; reconstructing data based on analyzing the datastream and determining the data manipulation technique; and storing the reconstructed data in a computer readable medium, wherein the reconstructed data contains manipulated data, wherein the reconstructed manipulated data is manipulated using a second data manipulation technique.
