Hi you could probably do it with rsync, but it's going to take quite
some work because that's not what rsync was really designed for. Instead
of going against the grain I'd recommend you setup a PC with apt-cacher:

$	sudo aptitude install apt-cacher -y

(This is from universe).

Then you will need to edit the configuration files:

$	gksudo gedit /etc/default/apt-cacher

and change "AUTOSTART=0" to "AUTOSTART=1" then save and close this file.

Next edit apt.conf:

$ 	gksudo gedit /etc/apt/apt.conf

And change "Acquire::http::Proxy "false";" to "Acquire::Proxy "false";"
just by deleting six characters in the middle. Then save and close this

Then run the command:

$	sudo /etc/init.d/apt-cacher start

By default all packages you download from now on will be stored
in /var/cache/apt-cacher, if you don't like this you can change it and
many other options in /etc/apt-cacher/apt-cacher.conf  .

ONE MORE THING!! You must change your sources.list to use apt-cacher....

$	gksudo gedit /etc/apt/sources.list

Changes all the sources that you want cached like this:

deb dapper-updates universe

deb http://localhost:3142/ dapper-updates
universe multiverse

So you're just adding in localhost:3142 at the beginning. This is
obviously for the machine the apt-cacher is running on. For the other
computers on the network to use the apt-cacher resources you will need
to replace "localhost" with the IP of the host machine, so it may look
something like this:
deb dapper-updates

Also make sure if you are using some kind of firewalling on the host
that access to port 3142 is allowed, if you haven't installed any
firewalling then it should be OK and won't need additional

Just to let you know what it's all about. Next time you download some
packages they will be stored in /var/cache/apt-cacher so you won't need
to download them again in the future. It works very very well for me
indeed and once you've been using it for a while you get a really good
collection of packages. If you want to import the packages that you have
already on your system into apt-cacher you will need to run the import
script by doing:

$	sudo /usr/share/apt-cacher/ -R
-r /var/cache/apt/archives

I think that should pretty much cover it for you, need further help just
ask. That concludes the longest email I've EVER written!

PS. If you have your /home on a seperate partition then I would store
the apt-cacher files there so in the event of deletion of the root
partition you will still have all your packages handy for the
reinstallation. Just do the following:

$	sudo mv /var/cache/apt-cacher /home/.apt-cacher

This will make it a hidden directory to keep it from getting in the way.
If you don't want it hidden remove the "." from .apt-cacher. Then you
need to edit the configuration file:

$	gksudo gedit /etc/apt-cacher/apt-cacher.conf

Change "cache_dir=/var/cache/apt-cacher" to

One final word of warning that should probably go at the beginning is to
make backups of all you configuration files BEFORE you mess with them.
As an example:

$	sudo cp /etc/apt/apt.conf /etc/apt/apt.conf.bk

Is good, just replace the path and file with the path and file you are
wanting to edit.
