MysqlデータベースのZRMサーバーで増分バックアップを復元しています。テーブルにblobデータがあります。増分バックアップが復元されず、mysqlエラーunknown command '\0'
が発生します。
max_allowed_packet_size
を1GBに変更してみましたが、問題が発生しました。 --hex-blobを追加するためにZRM構成を確認しましたが、役に立ちませんでした。
--verboseを使用してバックアップを復元した後のエラー:

どんな提案でも大歓迎です、そして前もって感謝します。
取得したblobデータのバックアップを復元するソリューションが得られなかったため、Unknown command
エラーが発生しました。この復元エラーを回避するために、extra-mysqldump-options="--hex-blob --skip-extended-insert"
ファイルにmysql-zrm.conf
を追加しました。
これが誰かに役立つことを願っています!!
