  • configuring a plurality of geographically diffuse network attached file servers to operate a file migration controller and to store a file migration control table;

    configuring said file migration control tables to include an entry designating a root device, and at least one time-decaying access control parameter for a file stored locally to one of said servers;

    receiving by a first server a request from a second, geographically remote server for access to an authoritative copy of a file stored by said first server;

    updating said time-decaying access control parameter to reflect said remote server'"'"'s request;

    computing by a server a relative access measurement comparing requests from said remote server to requests received from users of said first server; and
