SD cards have a habit of failing, typically when you have just forgotten how you configured them
I have made an image of my working SD card, so getting station back online if/when the inevitable happens should be simple.
However the ADS-B receiver generates live data, and I would also like to be able to backup/restore this.
At present I am using “rsync” to backup to another server.
I’m only doing the “/var/lib/collectd/” directory. Web pages appear to rebuild themselves in about an hour.
Are there any other files/directories I should consider?
