Not really. I maintain backups (one local, one offsite, one snapshotted and stored on a flash drive I carry around with me) of everything at home, including my OpenWRT devices and the configuration of my Pi-Hole. The Pi-Hole is running on an SBC so I also periodically take local images of it with dd in case I need to write a new microSD card and boot it up. I'm not the only one at home that relies on a net.connection every day, so I have to take other folks into account for resilience.
