Method and system for managing client data replacement

摘要

A computer-implemented method of managing replacement of a data file residing on a client computer to correspond to a new version residing on a server computer, the data file comprising one or more parts, the parts being sequentially ordered and grouped in plural consecutive chunks. The method comprises identifying those parts of the data file which are identical in the data file and the new version, identifying chunks comprising parts which are so identical, creating replacement chunks comprising parts not comprised in the chunks identified in the previous step, and causing only the replacement chunks to be transmitted to the client computer over a network.
