You're actually not the first to mention rsync, I'll man rsync and see
what I can get!

That's actually a very good point. The only thing is that the machine
doesn't generate any revenue and so it'll heavlily depend on the price
of the RAID controler really... I know there is none at the moment which
is why I was looking into dd and tar. I've read that dd physically
read/write every blocks of the disk whereas tar handles `zero-files`
differently... Thus my question!

Good point, and I'm fully aware that one of the reasons win2k3 requires
so much ram is the bloody UI! But I figured that with 2 ghz... I might
give it a try! My concern tho' is really about configuring X... I've
installed Centos on a test server here, and the X config is based on the
server video/audio cards + monitor... What happens there there are
none!!? :P

Thx for your time... You made me realise that even RAID1 could be
usefull (don't know why, I was under the impression that with only two
disks raid wasn't worth it...!?

Cheers Brad!
