Hi!

Thanks for your answer!

To follow up on earlier implementations, I understand they are similar 
in design, but is there any documentation? Maybe the critical point is 
to get it written down and thought through so it's easy to use and all 
variants are designed with security in mind.

SSH for starting the backup and optionally for tunneling, as it is no 
effort. In this context, a client is the computer, the user is the 
person using it. And my goal is automation. However, I realized that 
when using client initiated tunnels, the web start is broken. But that's 
just a feature change.

Yes I vaguely remember that. Kind of the VPN-idea I had to just leave 
the tunnel there.

Depends on variant. Passive "vpn" - nothing, queue - normal rush hour 
handled by BackupPC, dump - hell is loose but it should pass...
Oh, and the idea is of course to allocate a unique port for each client 
when tunneling, so no mistakes about who's being backed up.

Johan
