Sorry, I think we have a misunderstanding. I am the person of this thread and you did not point me to the FAQ 
The channels are up and running and functioning OK, so I do not think the channels need restoring. Also I can send and receive with the wallet. The only problem is: the wallet will not be recoverable if things should go wrong in the future.
My question is what steps to take to have a node with a wallet that can be recovered, should things go wrong.
