Estou restaurando um backup incremental com o servidor ZRM no banco de dados mysql. Eu estou tendo dados de blobs nas tabelas. O backup incremental não está sendo restaurado e causando erro no mysql unknown command ' . max_allowed_packet_size'
Tentei alterar o %code% para 1 GB e também obter o problema. Verificou a configuração do ZRM para adicionar o -hex-blob, mas não adiantou.
Erro após restaurar o backup com --verbose:

Todas as sugestões são muito apreciadas e agradecemos antecipadamente.
Não obtivemos nenhuma solução para restaurar o backup de dados do blob capturado, causando Unknown command de erro. Para evitar esse erro de restauração, adicionamos extra-mysqldump-options="--hex-blob --skip-extended-insert" no arquivo mysql-zrm.conf .
Espero que isso ajude alguém !!
