My current configuration is 2 RPi3s running Kodi. One is linked to the TV via HDMI and the other is running TVHeadend server headless. I'm (slowly) moving over to a single RPi4 and I'd like to avoid having to mess with the TVHeadend settings (Rumster Forest but needs different channels from those TVHeadend sets).
Is it possible to back up the necessary bits using SSH? If so how?
