Can you maybe remember when that hapened? What did you do to 
"investigate"? We analyzed on here, but still can not reconstruct a 
situation that lead to the described behaviour. Maybe you remember more 
information?

Ok, here is why files are deleted:
a) on the client: The files are listed in the client journal and have 
not changed (compared to the database entries). Now on the sync run the 
server has the files not longer in the listing. That means they have 
been removed on server side and that is done than on client side as well.

b) on the server: very similar, the files are in the client database but 
not longer present in the physical local file system. That means they 
were locally deleted. If they are still in the same state as before on 
the server, the local remove is propagated and the files are deleted on 
the server.

Benjamin, can you provide the server access log of that accident?

Thx,
