What is $Conf{FullPeriod} and $Conf{IncrPeriod}?
I would guess $Conf{FullPeriod} is 28-30 and $Conf{IncrPeriod} is 10.
The reason there are more than 3 fulls kept around is that each
incremental needs the original (dependent) full so that the
incremental can be "filled in" in case you browse or restore
that backup.
So keeping 18 incrementals 10 days aparts requires fulls
all the way back for 180 days, which is around 7 fulls at
a 28-30 day period.
If you reduce the number of incrementals you keep then the
older fulls will get deleted.
