    Fixes MariaDB backups failing since MariaDB 10.11.19 and 11.4.13.
    Mariabackup copied the data directory of ``mariadb_backup_host`` but
    connected through the load balancer, which could route it to a different
    Galera member. The backup lock then applied to the wrong node. It now
    connects to the MariaDB instance on the host it backs up.
upgrade:
  - |
    ``mariadb_backup_target`` no longer has any effect. Backups are always
    taken from ``mariadb_backup_host``.
  - |
    Full backups are now named ``mysqlbackup-<date>.qp.xbc.xbs.gz`` and
    incrementals ``incremental-<date>-mysqlbackup-<date>.qp.xbc.xbs.gz``,
    matching the restore documentation. Existing backups remain restorable.
