Full backups are all pretty much the same to backuppc - there's no
concept of which are weekly/monthly/yearly. If you are doing fulls once
a week, your 'daily' requirement will be met by keeping 6 incrementals
which will automatically force the backing fulls to be kept. You'll
then have to use some variation of exponential expiration to approximate
the full ages you want: $Conf{FullKeepCnt} = [4, 0, 12] should keep 4 at
your FullPeriod intervals, and 12 at 4x that interval. If that's close
enough to the 1 yearly, it might be OK. If you meant you want one from
another year back you can't quite hit it with powers of two, but
[4,0,12,0,0,3] might work (3 at 32-week intervals). You might also want
to set FullKeepCntMin to keep some number from ever aging out even if
you stop making new backups.
