I used to keep a backed up base image to reflash a corrupted sd card. But after the 3rd or 4th time i knew i had to find a better solution.

I eventually moved to docker on the pi. But the pi would randomly go down. I had two of them for redundancy but eventually one of them ended up corrupting its sd card and shortly later the other went down unexpectedly while i was at work and the whole family lost connection without knowing how to fix it.

Decided to move to to dns blocking on the router. Basically its easy to reboot for the family and has yet to fail (more than a year now).

I like it but just not on a Pi. I found it too unstable. I found it easier to host in a docker container.

Although these days i just use blocklists on my router.
