@jkandasa Of course I will share it ...
I set MyC to back up to a server /mnt/server.
Then made crontab job to copy from the server back to the myc sd card.
No need to worry about sorting by date or anything as MyC backup has been set to only keep so many backups and therefore that is all there will be when I copy the server backup directory back to the SD card....
Thanks for the reply. In answer to your questions.....
The pro mini is connected via serial connection to the pi (tx/rx on pro mini to tx/rx on pi). I chose 3.3v pro mini as then there is no level shifter needed.
It is definitely being picked up by the compiler as the serial rate between the pi and promini works at 38400. If this were not picked up I would expect 115200. I don't have a nano anywhere, but could try a uno or mega.
I now am running on a 'Pi Hut' 5V 2A supply and have had 2 junk node id's already this morning (But this time both from the same node I think, so will look into that as well). I am also going to see what good power supplies RS Components has and probably add a mains filter as well.
