Patent ID: 7219103

Claim:
A computer system, comprising: a source subsystem, wherein the source subsystem is operable to issue a write statement, wherein the source subsystem further comprises, a source node operable to issue the write statement; and a source storage device operable to store data and meta-data and changes thereto in response to the write statement; a target subsystem, wherein the source node and the target node are communicatively coupled and wherein the target subsystem is external to the source subsystem; a repository subsystem, wherein the repository subsystem is external to each of the source subsystem and the target subsystem; wherein the repository subsystem is communicatively coupled to each of the source subsystem and the target subsystem to facilitate the communication of data between the repository subsystem and the target subsystem and between the repository subsystem and the source subsystem; and wherein the repository subsystem is operable to queue the write statement issued by and received from the source subsystem and deliver the write statement to the target subsystem; and a network, wherein the source subsystem and target subsystem are communicatively coupled across the network.
