METHOD FOR HORIZONTAL SCALE DELTA ENCODING

Data can be transferred between computers at remote sites by transferring the data itself, or by transferring files showing how data at an originating site can be recreated from data already present at a receiving site. As part of the data transfer, a determination can be made as to what is the most appropriate way for the transfer to take place. Further, in cases where data is not transferred directly between originating and receiving sites, it is possible that some preparatory steps might be performed to improve the efficiency of the transfers to the receiving sites when they do take place. Additional efficiencies can be obtained in some cases by using the parallel processing capabilities provided by a cloud based architecture.
