Wow... this is what I love about this bunch. I'm glad to know the version of Clonezilla in the repos will run in local unicast mode, too. Should have been obvious if I had stopped to think about it.
@rise82: From this, and from your specs, it sounds like your best bet is to try the repo version (if you have it installed already) unless you need the ability to image other systems, too. The most generic Live CD (that covers the widest hardware range) is the i686. The amd64 only covers 64-bit hardware, and the only advantage it has is the multi-core optimizations make it a bit faster. Personally, I haven't played with the AMD C-Series processors at all, so, if bandwidth is at a premium, go with the i686. What you lose in speed you will gain in versatility (everything Pentium Pro and later should run it equally well). i486 is only for older 32-bit hardware.
Redo Backup is a good, simple tool, and I think will do everything you're needing unless you need multi-cast.
In that case, hit the Server Edition documentation at clonezilla.org
and do the configuration work to get DRBL up and running (there is a DRBL package in the repos that should have installed and been already working, though, when you installed Clonezilla... hmm.)
If you decide to do the Live CD thing with Clonezilla, the docs are here
. Plenty of screenshots, and good detail on getting started. Remember i686.
As so many have already said, learning to use mylivecd is worth doing. I've only used it for basic stuff as I explained earlier, but it can be quite useful and versatile.
Talk to all y'all...
