docker-mysql-cron-backup VS docker-pi-hole

Awesome backup utilities like this for mysql/mariadb, this one for postgres, and this one for Docker volumes. Along with Duplicatti which can also be run via Docker, this all makes for incredibly simple data backups that are also stored encrypted and off-site in case of an emergency. Since my configuration is also stored in Git, I could be back up and running in the event of hardware failure with very little effort.

Yesterday I deployed the official pi hole docker container on my raspberry pi 3 and set a custom DNS address on my phone addressing to the pi.

You could have a look at docker and try to run a more recent Ubuntu image on the Nano https://github.com/pi-hole/docker-pi-hole

My advice would be either use the docker-pi-hole documentation/quick start, or contact the content creator.
