[NCLUG] Server-to-Server backups

To be even more pedantic, and fail-safe, it looks for files with mtimes
newer than the START of the last rolling backup run that successfully
COMPLETED.  :-)

That is:  Note the time in a touch-compatible format, do the backup,
then touch the last-run file time to the start time.  This way you could
miss one or more backups, but eventually roll all recent files to the
shadow without missing any.
