I use ZFS under everything (including docker) and so I can use scheduled snapshots, backups, etc, to do the real data management, and not worry about losing data. I can use host mounts too, but I prefer to just back up and manage all of docker, out of band, without thinking too much about it. EDIT: granted this is for relatively small databases though. I think it could be scaled up however.
