Hello Christophe,

Thank you for the report.
Looking at the "MySQL Server-Tool Compatibility" at https://dev.mysql.com/doc/mysql-compat-matrix/en/ it seems to me that what you are trying to accomplish is unsupported operation.

i.e MySQL Enterprise Backup 8.0.12 is incompatible with earlier MySQL Enterprise Backup versions—it does not work with backups created with them.

More details here https://dev.mysql.com/doc/mysql-enterprise-backup/8.0/en/meb-legacy.html
