    organizing the modified files list as a B+ tree;

    updating the modified files list as a file is added to, removed from, or changed on the volume;

    selecting a way-point epoch timestamp; and

    using a backup tool to archive all files listed in the modified files list which were added to the modified files list before the way-point epoch timestamp.
