MySQL ZRM 恢复失败，mysql 错误未知命令 \0

我正在使用 ZRM 服务器在 mysql 数据库上恢复增量备份。表中有 blob 数据。增量备份未恢复，并出现 mysql 错误unknown command '\0'。

尝试将其更改max_allowed_packet_size为 1 GB，也遇到了问题。检查了 ZRM 配置以添加 --hex-blob，但无济于事。

使用--verbose恢复备份后出现错误：

非常感谢您的任何建议，并提前致谢。

我们没有找到任何解决方案来恢复导致Unknown command错误的已获取的 blob 数据备份。为了避免此恢复错误，我们已添加extra-mysqldump-options="--hex-blob --skip-extended-insert"文件mysql-zrm.conf。

希望这对某人有帮助！
