A data replication system and method. The method and apparatus provides for an efficient means of replicating data over a network in the form of a file between two individuals, or within defined groups of individuals, using a variety of devices to access the Internet, including computers, personal dat a assistants (~PDA~s) and wireless devices. A group is formed through an exchange of invitation, acceptance, and welcome messages. A group member designates a replication directory on the group member~s computer. Files placed in the directory are replicated and stored in the replication directo ry of each of the other members of the group. Any change to a replicated file causes a message by one member to be sent to all other members. Changes are conveyed via patches that represent the changes made to a replicated file. Replicated files are saved without replacing previous versions of the replicated file. The group formation and file replication processes are accomplished using existing network protocols.
