[Help required] Backup of the ZHA Network

Hello everyone one,

I have found a tutorial on YouTube where they guy performs a backup of his ZHA Network (and migration to another Gateway). The problem is that he performs this on his Docker installation.
I have a Virtualbox Image where HA runs.

Because I am a total noob in Linux, I would like to ask your help in starting the Python venv from OpenSSH and Terminal.

A second question: did anyone manage to SSH from Mobaxterm? I am getting an error regarding the login method (public key), which i don’t know how to configure on Mobaxterm.

I know that I will get all the needed answers. So… Thanks in advance!
