automatic backups of Pi-Hole (docker), see comments

backup.sh

#!/bin/bash
cd /backup && pihole -a -t

pihole.sh

#!/bin/bash
docker exec pihole-container-name /backup/backup.sh
rsync -avrg /path/to/pihole/backup/ /path/to/backup/storage/pihole/
find /path/to/backup/storage/pihole/ -type f -name '*.tar.gz' -mtime +30 -delete

1] add a volume to the docker via run or compose.
-v /path/to/pihole/backup:/backup

2] inside that folder, add the backup.sh, besure to chmod +x.

3]now whenever you run:
docker exec pihole-container-name /backup/backup.sh

it will create a Pi-Hole teleport backup .tar.gz in /path/to/pihole/backup that you can then backup however you like.

i use a daily cron that runs the pihole.sh
