We got a good deal on some servers and so we bought two of the exact same spec. They're building now.

We were hoping to have one of those serves be a "clone" of the other, data and all. Each would has a IDE drive and 3 SCSI hardware raid drive(s).

Is there any way to have a script or write one that copies all the files that we need/want onto the other server?

1. You can use dd (info/man dd).
2. You can use cp -arPR "source partition" "destination partition". In this case you use the minimal cd and mount the partitions.

Livecd is not an option. I want this to run automatically at night?

You can write a small script.
It is not possible to copy partitions completly while under use.

I don't need to copy partitions. Just certain dirs.

Why can't you use rsync to copy the data? That way you'd be able to only copy the changes and would be less stressful.
