What files to back up?

[PaddyB]

Thanks.  Here's a little node-red flow which backs up into /home/pi/files/backups 

The files/backups directories need to exist for it to work. 

Saves kplex.conf , all the files in .node-red, files and directories in .opencpn (so the logbook gets backed up, bit big this one so might need some trimming) &  openplotter.conf .

Hope this might be useful, any tips / ideas for improvement please share :
