Incremental backup?

Hi,

I have problems with incremental backup
and I have not been using tar this way before.

According to "man tar" "--listed-incremental" should be=20
"--listed-incremental=3D",
but I down know if that is my problem.

First I run monthly, which creates a complete backup.
but than weekly, and daily also creates the same size of backup.

Is it some configuration, or command option issue?

linux:/home/robert # cat /etc/hdup/hdup.conf

[global]
archive dir =3D /var/adm/backup/
date spec =3D iso
always backup =3D off
skip =3D on
force =3D no
overwrite =3D on
proto =3D /usr/bin/ssh
proto option =3D  -q -oProtocol=3D2
user =3D operator
compression =3D bzip
compression level =3D 6
exclude =3D lost\+found/, /proc/, /dev/, /sys/
nobackup =3D .nobackup

[bu-all]
dir =3D /
chunk size =3D 700m

[bu-home]
dir =3D /home
chunk size =3D 700m
