right!

No. I believe I would get one Backup every 4 weeks. 48 weeks each year. I
lost exactly 4 weeks ;-) Therefore 13 would be the correct number ;-)

? should be $Conf{FullKeepCnt} = [4, 0, 12, 0, 100]; for 100 backups every
16 month.

If I use:
$Conf{FullPeriod} = 7,6; # calculated as 365/12/4
$Conf{FullKeepCnt} = [4, 0, 12, 100];
I should get the weekly backups after 8, 15, 23 and 30 (exactly 30,4) days.
and I should get the monthly backups after 30, 61, 91, 122, 152, 182, 213,
243, 274, 304, 334 and 365 days.
And
$Conf{FullPeriod} = 7,61; # calculated from (365*4+1)/4/12/4
should respect also the leap year.
But to get a yearly backup every last or first week in a year is a
challenge, isn't it ?
Could /etc/cron.monthly provide a solution ?
