So, I was tidying up a Pi on my network which I use for various network tasks (PiHole, VPN, stuff like that), and I saw it had Apache and PHP installed. No need for that I thought, so I proceeded to clear up the packages I didn’t need.
After I was done I was checking things were good on my network and I noticed I couldn’t get to my local emoncms. You guessed it, I was logged into the wrong machine when I was tidying up. 
So, my emonpi is running a rather reduced OS now. I expect my best option is to take the card out and reflash it with a new image, but is there anything I can do from the command line to backup the configuration before I do?
(I’ve got a backup from a couple of weeks ago when I updated the SW version, but I’ve been modifying things a bit these last couple of weeks.)
