MySQL ZRM 還原失敗，mysql 錯誤未知命令 0

我正在使用 mysql 數據庫上的 ZRM 伺服器恢復增量備份。我在表中有 blob 數據。增量備份未恢復並給出 mysql 錯誤unknown command '\0'。

嘗試將其更改max_allowed_packet_size為 1 GB 並且也遇到了問題。檢查 ZRM 配置以添加 –hex-blob 但沒有用。

使用 –verbose 恢復備份後出錯：

任何建議都非常感謝，並在此先感謝。

我們沒有得到任何解決方案來恢復所採取的 blob 數據備份導致Unknown command錯誤。為了避免這個恢復錯誤，我們extra-mysqldump-options="--hex-blob --skip-extended-insert"在mysql-zrm.conf文件中添加了。

希望這對某人有幫助！
