Time and bandwidth efficient recoveries of space reduced data
摘要:
A method, article of manufacture, and apparatus for efficiently recovering information are disclosed. In some embodiments, this comprises receiving a datastream and analyzing the datastream for chunk headers, data chunks and chunk maps. The chunk headers are then used to determine the data manipulation technique of the data chunks. In some embodiments, the chunk headers contain information about the size of the manipulated and un-manipulated data chunks. Data is then reconstructed from the datastream analysis and data manipulation technique determination. The reconstructed data is then stored in a computer readable medium. In some embodiments, the reconstructed data may be stored in multiple destinations. In some embodiments, the storage of the reconstructed data in multiple destinations may be simultaneous.
