I'm not a MySQL expert by any means, but isn't it possible to get a
quiescent backup of MySQL without stopping/starting any services?

It's my understanding that one can issue a "read lock" as part of the
mysqldump command. If this is the case, wouldn't it be less disruptive to
users since the web and email services would not be shutdown in order to
perform a backup.

I have also read that this "read lock" works particularly well when using it
to backup a replica, since this would require zero down time.
