Today I lost accidentally all my debian packages on our ftp server. This was a point where I thought, it may be a good idea to setup a working repository. So I backported reprepro and installed it. Some scripts by side and a smooth setup is running. :-)
Maybe you wonna add to your /etc/apt/sources.list:
deb ftp://ftp.cyconet.org/debian unstable main non-free contrib
or:
deb ftp://ftp.cyconet.org/debian sarge-backports main non-free contrib
