Abstract: A method of maintaining a computer file in synchrony between multiple computers is disclosed. The multiple computers may comprise at least one ancestor, a descendant of the ancestor, and a subsequent descendant of the ancestor. A local copy of the computer file may be stored at the ancestor, the descendant and the subsequent descendant and a change log may be maintained at the ancestor, the descendant, and the subsequent descendant, with each change log reflecting changes to local copies of the computer file. The descendant may pass entries in its change log to the subsequent descendant. These entries may be consolidated with the subsequent descendant's change log and may be passed to the ancestor. Changes to the local copies of the computer file at the descendant and the subsequent descendant may be synchronized with the local copy of the file at the ancestor using change log entries received from the subsequent descendant.
