For each service I run, I have a volume for the persistent storage. For example: Nextcloud has a maria (mysql) db and a server. In my /opt/nextcloud I have a script for creating/updating the docker images. Persistent data lives in /opt/nextcloud/srv/{db,data}. I used systemd for management/dependencies (I don't use docker compose, just simple, single instances that are easy to recreate). Everything is backed up daily using rdiff-backup.
