drobo is the hot new(2 yrs old) device, that makes redundant arrays of independent disks an easy easy proposition.
They sell the Vanilla Drobo on Amazon for just $350 now, and you can buy 1.5TB Seagate 7200RPM drives on there for $109 a piece to populate your Drobo.
There are discussions and forums online discussing how and if a drobo can be used with or without an Airport Extreme, a Network, Time Machine or many other details. These date back to April 2008 when there were some restrictions, you could only use 2TB for storage and other factors. But today the situation is as follows:
Plugging your Drobo into a Mac in your office through the Firewire 800 port, and installing the Drobo utility will allow you to format the disks you’ve loaded as you please. This process can take five minutes. The next step is to connect your formatted drive to your Airport Extreme and mount it on your office Macintosh(es), enable it as a Time Machine Backup location, and Bob’s your uncle.
