ABSTRACT:
The present invention is directed toward methods and systems for data de-duplication. More particularly, in various embodiments, the present invention provides systems and methods for data de-duplication that may utilize a data de-duplication system that retrieves data from a data storage device in an order based on the location of blocks on the data storage device. Some embodiments break a data stream into multiple blocks of data and store the blocks of data on a data storage device of a data de-duplication system, wherein a code representing a redundant block of data is stored in place of the block of data. A location for each block of data may be stored. Additionally, the blocks may be read in an order that is determined based on the location of the blocks.
