However, if your purpose is simply to mirror, rather than to continually
test the latest backup, then it's probably considerably more *efficient*
to use rsync.  In fact, *unless* you want to do the daily restore as a
test to make sure the backups are good, you might want to consider
mirroring the live machine to the warm standby with rsync, then backing
up the warm standby.
