(if that service goes down, everyone in my house gets mad at me)

I bought a PiZero and set it up as a redundant pihole for this reason. It’s slower because it’s wireless, but not super noticeable since it’s ‘just’ DNS. I have the router pointed at the main and backup all the time and if I need to do something (or break the main one messing with dockers) there’s still the backup until I get the main up.

I messed around with some High Availability configs where they both had the ‘same’ ip but could never get it working smoothly. I just use the teleporter functionality within pihole any time I update anything to keep them in sync, which is rare.

Only real reason IMO is dust can collect on the seam and it’s annoying to clean without taking the peel off anyway.

IDK why people get weird about it.

The second one.

Mirroring is good for speed, but a storage mechanism with parity checks will always be more recoverable. And you will have far more storage available.

Is your home connection down that much? I’d think that even syncing once every day or so would populate everything fine, and if you’re at home it should update over wifi.

I might just be spoiled because I’m the only one using mine and only for a handful of devices.
