[CentOS] backup server..

Hi, 

I've been playing with CentOS quite a bit lately (and I must say it's
growing on me!! :) and I was now able to convince my boss that we could
get a box and gradually start migrating our hosting from win2k3 to
centos.

So anyway, I've got a new box at the colo ready up and running - P4 3Ghz
w/HT 2Ghz RAM 2x70Gb HDD, running Centos4.4 fully up-to-date. Now my two
questions are;

(1.) In terms of backup, I'd like to have a cron sending out an nightly
incremental backup of user files. I'd also like to have HDA to be copied
backed up entirely (maybe weekly) onto HDB (were're not going to use
140GB anyway!) so that is hda crashes, I`d swap both of the hdds and
boot from the backup. Now for that second step, I was reading that dd
was quite CPU intensive? Would there be other alternatives? Advices on
doing backups?

(2.) I've got no physical access to the box, and the box has obviously
no video or sound. Considering this, would it possible to remotely
administer the box using VNC in a GUI environment? - I figured 2Ghz
could probably handle me starting x sometimes...! So if possible.. How
would I do it? I`m assuming there are no `yum install x`....

Anyway.. Thanks for any input you may have on the both topics!

Cheers, 

Seb.
