      Description

      Since MDEV-17591, MariaDB has installed mariadb-backup as an alias for mariabackup. See here:

      https://github.com/MariaDB/server/blob/mariadb-10.4.11/cmake/symlinks.cmake#L15

      Similar aliases are installed for other commands. For example, mariadb-binlog is installed as an alias for mysqlbinlog. As part of this change, the mysqlbinlog utility now reads options from the [mariadb-binlog] option group as well. From client/mysqlbinlog.cc:

      static const char *load_groups[]=
      { "mysqlbinlog", "mariadb-binlog", "client", "client-server", "client-mariadb",
        0 };
      

      https://github.com/MariaDB/server/blob/mariadb-10.4.11/client/mysqlbinlog.cc#L96

      However, mariabackup does not yet read from the mariadb-backup option group. From extra/mariabackup/xtrabackup.cc:

      static const char *xb_client_default_groups[]={
         "xtrabackup", "mariabackup",
         "client", "client-server",
         "client-mariadb",
         0, 0, 0
      };
       
      static const char *xb_server_default_groups[]={
         "xtrabackup", "mariabackup",
         "mysqld", "server", MYSQL_BASE_VERSION,
         "mariadb", MARIADB_BASE_VERSION,
         "client-server",
         #ifdef WITH_WSREP
         "galera",
         #endif
         0, 0, 0
      };
