This is my first post; apologies if I selected the wrong area.
I purchased the PiAware in 2019, and it has been running virtually uninterrupted since then. I allowed the upgrade from v5 to v6 within the web interface. With recent cyber alerts and warnings (in general, not with piAware) I started looking at my linux systems. I realized this one is running a very old OS, from 2018. I’m familiar with linux, and have SSH access to the device. But I’m wondering if it’s safe and is it recommended to update?
Also can somebody recommend a backup strategy? I’d like to perform an image backup if that’s an option.
the quickest way in your case ( since you use the sd card image) is to burn the current sd card image found here PiAware - build your own ADS-B ground station for integration with FlightAware - FlightAware to a new SD card ( keep the current one as a back-up), slip that into your Pi and then set the feeder id in the image to reflect your current feeder id that can be found on your ads-b stat page.
The new SD image is already created with Bullseye.
Steps below are copied from @abcd567 so thanks to him for the explanation for setting the feeder ID
STEP-1:
Go to My-ADSB stats page and copy the feeder-id (Unique Identifier), as shown in red rectangle in screenshot below.
STEP-2:
Issue following command to set your feeder-id.
(Replace xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx by Unique Identifer you have copied from My-ADSB stats page.
I have upgraded my operating system, however, I didn’t know about this step.
As a result, I now have a second site in my dashboard. Can I delete the “extra one”, or should I just accept the second site and ignore the first one?
A (slightly annoying) side effect of this is that the dashboard is displaying an alert that it hasn’t heard from one of my systems for a period of time.
You don’t have to, there’s probably a very slight security risk because it’s connected to the network but providing you’ve got a good first line of defence (no ports forwarded to the Pi, a strong password) then it’s probably not a worry.
I use raspibackup on all my Pis, it runs once a week and creates a compressed SD card image on my NAS. I’ve got it set to keep six weeks worth of history. I have had to use it to restore a Pi and it works well.
