Hello! Pleasure! Can i help me? i have its docker-compose

services:
  db-mysql-5.7.21:

    image: mysql:5.7.21
    restart: always
    environment:
      MYSQL_ROOT_PASSWORD: 'mypassword'
    ports:
      - '3306:3306'
    expose:
      - '3306'
    volumes:
      - /volume1/docker_compose/db_mysql_5.7.21_una/appdir/config:/etc/mysql/conf.d
      - /volume1/docker_compose/db_mysql_5.7.21_una/appdir/data:/var/lib/mysql
    networks:
      - myNetwork

  backup:
    image: databack/mysql-backup
    restart: always
    volumes:

    depends_on:
      - db-mysql-5.7.21
    networks:
      - myNetwork

networks:
  myNetwork:

but i find this error in databack/mysql-backup mysqldump: Couldn't execute 'SHOW FIELDS FROM host_summary': View 'sys.host_summary' references invalid table(s) or column(s) or function(s) or definer/invoker of view lack rights to use them (1356) cp: cannot stat '/tmp/backups/db_backup_2024-03-06T21:31:14Z.tgz': No such file or directory rm: cannot remove '/tmp/backups/db_backup_2024-03-06T21:31:14Z.tgz': No such file or directory

Looks like you are running the legacy bash-based version. Can you enable debug logging and post here? Just be sure to filter out any sensitive information.

Been digging into it, I remain stumped. There are various reports of similar issues. I thought it might have to do with mysql-backup using a newer version of mysqldump than your database, since the usage of sys tables changed. But I could not recreate it.

What happens if you log into the database container directly and run mysqldump?
