Duplicating Time Machine

[Michael73]

Can time machine be duplicated?

Here's the situation. I've got a MP with now with 4x500GB HDs. I'm using one of the internal HDs as a time machine drive to back up my boot drive. That leaves the other 2 drives that have some important stuff on them unbacked up. So, is it possible to create a second (or third, etc.) instance of TM and direct it to back up the other drives in a same fashion as my boot drive? Since all my internal drive bays are now filled, this assumes the new TM drives would be externals (either Firewire or eSATA).

I finally got an over the top response from AppleCare read on...

You cannot create duplicate copies of the app time machine only, but if you're crafty here's what to do.

(Internal) Drive 1: Start up disc (No partitions)
(Internal) Drive 2: Storage (No partitions)
(Internal) Drive 3: Storage (No partitions)
(Internal) Drive 4: 3 partitions
1 - Time Machine back up drive for Drive 1 (largest partition)
2 - Install of Leopard as a startup disc (small partition)
3 - Install of Leopard as a startup disc (small partition)
(External) Drive 5: Time Machine
(External) Drive 6: Time Machine

So here we go, TM on drive 1 backs up to drive 4 partition 1. TM on Drive 4 partition 2 backs up partition 2 and Drive 2 to External Drive 1. TM on on Drive 4 partition 3 backs up partition 3 and Drive 3 to External Drive 2.

Can anyone see why this wouldn't work?
