Try something like the following
# Full backup every 2 weeks
$Conf{FullPeriod} = 13.67;
# Keep 4 backups @ 2 weeks
# 4 @ 4 weeks
# 4 @ 8 weeks
# 4 @ 16 weeks
# 2 @ 32 weeks
# 1 @ 64 weeks
# Over 4 years backups ( 248 weeks )
$Conf{FullKeepCnt} = [4, 4, 4, 4, 2, 1];
# Incremental backup daily and keep 13
$Conf{IncrPeriod} = 0.67;
$Conf{IncrKeepCnt} = 13;
$Conf{IncrLevels} = [1, 3, 5];
