摘要： A system for efficiently transmitting data from a first site to a remote site over a communication medium. The data includes a storage for storing data in sub-segment boundaries, such that few sub-segments are accommodated in each block. The system further includes a storage for storing data including signature data. Each one of the sub-segments is associated with a signature of considerably smaller size than its respective sub-segment. The system includes a processor configured to perform the following, as many times as required: receiving a block and partitioning it into sub-segments. For each sub-segment in the block the processor calculating a signature. It then determines whether the calculated signature matches a corresponding signature, if any, stored in the signature storage, and in case of no match (indicating that the sub-segment is new or has been modified), transmitting the sub-segment to the remote site and store the calculated signature in the signature storage.
