Apologies, the backend does not seem to be doing this to begin with.

I'm not sure what the problem would be, other than some kind of
compatibility issue with ncftp and the server - assuming the control
connection is timing out during an active transfer, without the data
connection timing out.

Actually, which version of duplicity is this? ftplib is not used AFAIK
(I guess it was before?). If this is an older version, I'd recommend
upgrading before any further debugging is done. Particularly if you're
on one of those distros that have the age-old 0.4.10 and such (since
you mention Debian; I believe both sarge and etch have pretty old
versions; sarge definitely does).
