time machine osx server backup to multiple drives?

Hello,

I've just discovered Time Machine for Mac OSx Server. It can act as a centralizad point for the backups of all the computers in the network, how cool!

I know that Time Machine "client" can back a system up to multiple drives. My question is, can I do something similar with Time Machine "server" so I can have more than one storage product onto which I can back up all the systems? That would be very interestin if I want to implement a off-site backup from all my systems.

I would love to hear your inputs.Thanks in advance,

Regards,
