Double Backup Question? Time Machine + 2 HDD's + Time Capsule

[Pumapayam]

So if my current set up on my Mac Pro is (2) 1 TB drives.

(1) for use, and (1) for Time Machine.

Can I connect a 1 TB Time Capsule to essentially "back up my Time Machine back up"?

So I want to have (3) 1 TB HDD's, (2) in the Mac Pro, and (1) in the Time Capsule, all with the same information.

I basically need to know if the software is set up for a 1X's backup only, or can it copy the same information again as a redundant backup?

Thanks!

Time Machine can only back up to one drive at a time, even if it is backing up multiple drives. For other backups, you may want to make a bootable clone using Carbon Copy Cloner.

Thanks for the helpful response. I will attach this question with a follow up then.

So if I am stuck with 1 backup location only, what would you recommend since I want to update my wireless network in my house?

1. Retain my Time Machine setup "as is" can get an AirPort Extreme
   
2. Get a 2 TB Time Capsule, and have Time Machine back up there rather than within my Mac Pro.

Which is more reliable? my Mac Pro (1 TB HDD WD Caviar Black) or Time Capsule?
