I have 3 schedules per policy using calendar under 4.5. There is a
known bug with calendar. That is if your time schedule overlaps the 24
hour clock it will perform 2 backups in one evening because 23:59:00 is
one day and 00:01:00 (one minute after midnight) is another day. I had
the same problem...2 backups in one evening. When I changed the "window
of opportunity" to not extend past 23:30:00 the problem was resolved.
