without backing up the whole thing…
you can “share” those pedalboards and later do the “try now” option on them.
or copy over ssh.
# fetch all pedalboards
scp -r root@192.168.51.1:/root/.pedalboards/*
# copy/replace all pedalboards
scp -r *.pedalboard root@192.168.51.1:/root/.pedalboards/
# restart webserver afterwards
ssh root@192.168.51.1 systemctl restart mod-ui
