    hostname-dbname1-mar.sql.gz
    hostname-dbname1-mie.sql.gz
    hostname-dbname1-jue.sql.gz
    hostname-dbname1-vie.sql.gz
    hostname-dbname1-sab.sql.gz
    hostname-dbname1-dom.sql.gz
    hostname-dbname2-lun.sql.gz
    hostname-dbname2-mar.sql.gz
    hostname-dbname2-mie.sql.gz
    hostname-dbname2-jue.sql.gz
    hostname-dbname2-vie.sql.gz
    hostname-dbname2-sab.sql.gz

Example Playbook

If you want to create a new system and mysql user using lookup pass plugin:

    - hosts: localhost
      become: yes
      remote_user: debian

      roles:
        - role: gcoop-libre.mysqldump
          gcoop_mysqldump_create_mysql_user: yes
          gcoop_mysqldump_create_system_user: yes
          gcoop_mysqldump_mysql_username: mysqlbackup
          gcoop_mysqldump_mysql_password: "{{ lookup( 'pass', 'mysql/' + gcoop_mysqldump_mysql_username ) }}"
          gcoop_mysqldump_mysql_root_password: "{{ lookup( 'pass', 'mysql/root' ) }}"
          gcoop_mysqldump_system_password:     "{{ lookup( 'pass', 'users/' + gcoop_mysqldump_mysql_username ) }}"

When you already have a system and mysql user:

    - hosts: localhost
      become: yes
      remote_user: debian

      roles:
        - role: gcoop-libre.mysqldump
          gcoop_mysqldump_mysql_username: mark
          gcoop_mysqldump_mysql_password: dadada
          gcoop_mysqldump_mysql_root_password: 123456
