I think he means something else: have BackupPC process running on 
10.0.0.170, and have backup physically on 10.0.0.254.

What I do, is running iscsi-target[1] on a storage server (a server with 
lots of space), and iscsi-initiator[2] on a server running BackupPC.

If that sounds complicated, perhaps the best way to do it is to use NFS, 
CIFS (Samba) would be the next choice.

[2] http://open-iscsi.org, use the latest svn
