Yes they are in separate lines. After opening the ssh-connection (a real
shell, but I will change this for the future) the script waits 10sec. If
I remove the "sleep" the connection fails, perhaps the tunnel isn't
really ready?

Yes, this is the main reason.

This wasn't working for me, don't know why. But as I already said - I
don't think, that the ssh-connection is the problem. I can backup my
linux-pc with the same conifg using a ssh-tunnel, too.

I added it, no big different. But in the log of the client I found a
strange thing: The clients sends 27 (!) files more to the server than he
receives.
