slowly i get it. the "quasi standard" that i know of for syncing like this, you 
might want to call it real secure clouding, is putting your files into 
encrypted file containers, which in turn are synced into the cloud, or in your 
case on a file server.

i heard of scenarios where truecrypt/dropbox combinations work reliably as long 
as you do not attempt to work on them in parallel.

for your case i'd suggest to put all files into a truecrypt file container and 
sync this via rsync (rolling checksum) over to/from your file server.

duplicity is not fitting your purpose here. it is simply no sync tool.
