but database files are not normal user files and can't be backuped while 
the service is running in a safe way like your personal document files

you can put the data in /home/mysql, make a bind-mount from 
/var/lib/mysql to /home/mysql and change the config to use /var/lib/mysql

voila, ProtectHome no longer hits because from the viewpoint of systemd 
and mariadb the datadir isn't below /home
