TIME MACHINE and REMOTE SERVERS?

I have an XSERV that I just setup OSX10.5 and time machine. I also have another G5 server running 10.3 .. When the xserv had 10.4 I was using RETROSPECT to backup the XSERV and the g5 server to a firewire hard drive. Is there a way with TIME MACHINE I can tell it to backup the remote server as well as the XSERV that is is currently doing?

Thanks.....

Ok

Thanks for the response... Is there a freeware solution to backup my second server since the version of retrospect I have is OLDER and doesnt seem to work right on 10.5
