 Description   

User with appropriate privileges failed to backup non-galera MariaDB server while using option --galera-info.

KB says :- https://mariadb.com/kb/en/mariabackup-options/#-galera-info If the server is not a Galera Cluster node, then this option has no effect. But it does affect mariabackup , backup keeps failing for all CS.
