  • Patent number: 6738799
    Abstract: A server generates an update file for transmission to a client that permits the client to generate a copy of a current version of a subscription file from a copy of an earlier version of the subscription file. For each segment of the current version of the subscription file, the server searches an earlier version of a signature list for an old segment signature which matches a new segment signature corresponding to the segment. When a match is detected, the server writes a command in the update file for the client to copy an old segment of the client's copy of the earlier version of the subscription file into the client's copy of the current version of the subscription file, where the old segment corresponds to the segment for which a match was detected.
