ABSTRACT:
A computer readable file of an original state is updated to a final state. The original state and the final state are both states within a sequence (100) of states, which sequence (100) includes at least one hub state and one non-hub state. A first hub version, which corresponds to a hub state which is at least as early in the sequence as the original state, is stored locally. A hub incremental update (110) is retrieved (314) and used to update (316) the hub version to a second hub version, which second hub version corresponds to a hub state which is at least as early in the sequence (100) as the final state. A final incremental update (112) is retrieved (320) and used with the file of the final hub version to produce (322) a file of the final state. The files corresponding to both the second hub state and the final state are retained (324).
