Comment on Best way to keep a hot spare SD card for a raspberry pi?

My real backups are squared away, no worries. Nightly automatic restic snapshots, one to an external drive on this very pi and another to a NAS at my parents’ house.

I ended up making my router my DNS server, so if my router goes down, the internet is down anyway. I have static routes for things on my LAN, so if I hit mydomain.com, I can route it to an internal address instead of going over the internet. So far it works pretty well.
That said, I don’t have a PiHole setup, so I don’t know if that complicates things (I’m guessing pointing the router at the PiHole with a fallback to external DNS would just show ads or whatever if the PiHole is down).

I like the DNS on the router idea, I’ll look into it. I do have some split DNS set up as well as adblocking lists (technician). Not sure what my router can do.

I think most can do it (esp. if you flash something like OpenWRT), but I have an entry-level enterprise router from Mikrotik and that’s a pretty standard feature on that tier.
