Make restore cds(dvds)

See, I know with dd (I've not used partimage) that when you create an
image, you get a file the size of the partition (empty space and all),
that's no good for a couple of reasons...
1) if I have a 300g drive with a 10g install, I want to be able to use
a cheap 10g to back up to rather than fork over the premium for a 300g
2) in the case of an array, the space may very well be bigger than
available drives.
system imager btw, is a pretty good solution, it will backup filespace
(vs drivespace), however, to do this with a bootable distro and span
multiple dvd's is beyond my ability presently. Sadly, this is exactly
what mkCDrec claims to do but since I can't get it installed and can't
get support from them, it's moot.
I think in the long run, what we're going to end up doing is providing
an install with systemimager on a smaller drive. This would allow for
booting and instructions to run a bash script that will allow for
reimaging.
thanks for all the advice and help
