 Description   

The MariaDB Backup documentation currently shows the following disclaimer:

MariaDB Backup in 10.2.7 does not support --prepare --export functionality. This is planned for the next release. In this version you can workaround this limitation by preparing the backup as usual (without the --export flag), then start the server and execute FLUSH TABLES FOR EXPORT

https://mariadb.com/kb/en/mariadb/mariadb-backup-overview/#limitations

It may be a good idea to implement it at some point.

Note that the --export functionality currently seems to be broken in XtraBackup as well:

This should be done by internally executing SQL commands in mariabackup.
