Alright, if I understand this, you have your worker machines map  
share(s) that "Ubuntu" is offering on the network as local drives.   
Each worker machine, when it's done with its task, takes its data and  
copies it to the mapped shares.  This is working fine for all of your  
XP Pro machines, but your XP Home machine, "misty", can't see the  
shares offered by "Ubuntu".  Therefore, you're looking for a way to  
efficiently transfer the data from "misty" to Ubuntu for storage  
(which is currently stalling).  Periodically, you're looking to take  
what's on "Ubuntu" and back it up to some other media for archival  

Well, unfortunately, if this is truly how your set-up is configured,  
you don't have too many options.  Windows only recognizes cifs / smb  
shares natively.  So, you can't really export your shares from  
"Ubuntu" any other way.  You can possibly export your shares using  
NFS, but I don't know if this works well with NTFS or not.  Here's  
where you can get more information on an NFS client for Windows:

Depending on how you're doing your housekeeping on the "Ubuntu" box,  
you still could use rsync.  Rsync does have a switch "-W" in linux, at  
least which tells rsync to not use its normal rsync algorithm, but  
instead just copy the whole file.  It would still make use of the  
compression, though.

You'd set-up rsync to run in daemon mode on "Ubuntu" (rsyncd), edit  
the /etc/rsyncd.conf file to taste (more information by typing 'man 5  
rsyncd.conf' at the command-line) and then using the windows rsync  
client to copy files to the "Ubuntu" box.  Actual command (with  
switches and everything) would depend on your Windows implementation  
of rsync.  But, I would suggest perusing whatever included  
documentation came with it.
