It is not comparable, not even by far.
Assuming your are not a psycho, to safely drive a car is orders of magnitude (in plural) easier than modifying the Sw in a safe and deterministic way.
It is not only that bad people exists, it is about that making a small mistake can kill you
First, second and third most important point is : Tesla needs to allow the connection to an alternative server.
The fourth should be access to the api and data that are exchanged.
You shouldn’t mess with the FW of your own car even for some innocent feature like this one, you don’t know/understand the interactions that may happen between different Sw components and the hw layer, you can not provide a similar of level of testing, including some worst case scenarios, that can make your car unsafe during some problems or unforeseen conditions. And perhaps also, the car could loose its license for driving…
If tesla allows that, then we can start speaking about it. But last time I check on that was not possible
You will need to explain a bit further this statement to mild knowledged internet stranger…
Because the point of waf is exactly about reducing the exposed surface…
Some clarifications :
The 3 2 1 rule applies only for the data. Not the backup, in my case I have the real/live data, then a daily snapshot in the same volume /pool and a external off-site backup
For the databases you got misleading information, you can copy the files as they are BUT you need to be sure that the database is not running (you could copy the data and n the middle of a transaction leading to some future problems) AND when you restore it, you need to restore to the exact same database version.
Using the export functionality you ensure that the data is not corrupted (the database ensure the correctness of the data) and the possibility to restore to another database version.
My suggestion, use borgbackup or any other backup system with de duplication, stop the docker to ensure no corruptions and save everything. Having a downtime of a minute every day is usually not a deal breaker for home users
Then don’t buy tesla, or force legislation about introducing such feature.
But make yourself a favor and don’t play Russian roulette with something that you can not understandbecause there are not data available.
And for final tip, if you really cares about that then enforce the fsf (fsf.org)
