摘要： PROBLEM TO BE SOLVED: To provide an improved method for producing the accurate copy of a source file by a receiving computer.
SOLUTION: When the receiving computer (22) has a reference file (46) that is similar to a source file (46) to be transmitted by a sending computer (20), only differences between the two files are transmitted. In this invention, the data in the reference file is divided into a plurality of blocks, each block is associated with a key value and the key value is compared and the key values are sent to the sending computer in the form of an array. A block of data at the source file is identified, its key value is computed and the key value is compared to the keys in the array. When a match is found, an indication of such is sent to the receiving computer, otherwise, a byte of data from the data block is sent to the receiving computer, a subsequent block of data is identified and analyzed. The latter steps are repeated until a representation of the source file is present at the receiving computer.
