Besides adding a UPS, how do you deal with power failures? Are you somewhere where they’re not much of a problem?
In my experience mini computers don’t handle power failures nearly as well as purpose-built hardware.
After several power failures the SSD on my Raspberry Pi became so corrupted it wouldn’t boot, and I was 250 miles away at the time and lost access to my home network for weeks. Overlay file systems work but are a PITA to maintain. By contrast my routers have never had a problem even with repeated power failures, so instead of relying on the Pi I’ve moved my DNS and Wireguard servers to my router.
Power loss protection on SSDs is an interesting addition I hadn’t come across before.
We live in a very windy area and power blinks are common. A high endurance MicroSD was in use the first time the Pi wouldn’t boot, but I was in town and it was just annoying. It was a big issue when the Pi wouldn’t boot from the SSD while I was out of the country.
We don’t have high bandwidth demands so any decent OpenWRT router works fine and supports both Adguard Home and Wireguard. What I really like about putting WG in particular on the router is that if the router is up, WG is working, and the routers come back up without fail after every power outage. A 2nd Wireguard instance still runs on my Pi but since switching to WG on the router a year ago there hasn’t been a reason to even connect to it.
My problems with the Pi had me looking for other solutions and I ended up with a mini Dell laptop running Debian. (Can’t easily run WG on it due to some software conflicts.) It alleviates the need for a UPS and runs for 6+ hours if the power goes out, rather the minutes provided by my small UPS.
One of these days I’ll find a bogus reason to talk myself into upgrading the router with more powerful hardware. Mikrotik looks like a great option and I’ll take a look at RouterOS. Thanks for the info.
