Method and system for efficient data transmission with server side de-duplication

摘要

The invention provides a method and system for reducing redundant data blocks. The method includes encoding a first data block having a first length into a bitstream having a second length, transmitting the bitstream to a server device, and reducing redundant data blocks by decoding the first data block from a first plurality of data blocks and the bitstream where each block in the first plurality of data blocks has a length equal to the first length.
