I just use dd with a live CD. 

to make the image, splitting it across gigabyte size files, putting the
images directly on a windows file server:

Boot with live CD and...
for p in `cat /proc/swaps | grep partition | awk '{print $1}'`; do sudo swapoff $p; done
mkdir image_dir
sudo mount.cifs //server/images image_dir -o uid=ubuntu,gid=ubuntu,ip=192.168.X.X,username=foo
cd image_dir
sudo dd bs=900k if=/dev/hda | gzip --fast -c | split -b $((1024*1024*1024)) -d - image-`date +"%Y-%m-%d"`-gz.

to dump the image back:
Boot with live CD and...
for p in `cat /proc/swaps | grep partition | awk '{print $1}'`; do sudo swapoff $p; done
mkdir image_dir
sudo mount.cifs //server/images image_dir -o uid=ubuntu,gid=ubuntu,ip=192.168.X.X,username=foo
cd image_dir
cat drive-image-2006-03-08-gz.* | zcat | sudo dd bs=900k of=/dev/hda
