It has been a couple years since I have used it, but I am sure I did  
it across a network via SMB.  I no longer work there, so I  
unfortunately don't have access to what I did.

I remember it being over a network because the www server was  
separate from the backup server.  I may have done it on the Windows  
machine and had the remote N*X SMB mounted as a network drive. I  
think I also used putty on a Windows server to make an ssh tunnel to  
work over at another project.

To my great fortune I don't currently have to deal with windows at  
all (currently).
