バックアップをリモートのPublic Cloud上のオブジェクトストレージに直接送り、DR, BCP対策を行う事が可能ですが、mysqlbackupにもオブジェクトストレージに直接バックアップを送るオプションがあるので、OracleのPublic Cloudを利用して動作確認しました。

※ 2017年3月現在、MySQL Serviceが日本のデータセンタでは提供して無い為、EUの検証環境に対して検証を行いました。
開発環境としては、Enterprise版のモジュール、サポート、コンサルティングサポート含めて利用する事が可能ですので、TCOの削減が可能ですが。レスポンスが要求される本番環境としては、日本のデータセンターでのサービスが待ち遠しい所です。

  

検証したmysqlbackupのバージョン
最新は、mysqlbackup4.1です。

mysqldump: [Warning] Using a password on the command line interface can be insecure.
Warning: A partial dump from a server that has GTIDs will by default include the GTIDs of all transactions, even those that changed

MySQLのmysqlbinlogコマンドでは、MySQL5.6からリモートにあるバイナリーログを読み取る事が可能になりましたが、SSLを利用した通信の暗号化はサポートされておりませんでした。

次期メジャーバージョンのMySQL5.7では、ここら辺も機能拡張されておりmysqlbinlogコマンドを利用して、リモートのバイナリーログを読み込み場合にもSSLを利用した通信の暗号化を行う事が出来るようになりました。
Firewall、セキュリティ機器、セグメント分割された環境で、何処まで必要になるかは状況次第ですが、
リモートサーバーが自然災害対策の為に、自分でインフラを準備する必要が無いPublicクラウド上にある場合などに通信の暗号化が出来ると安心ですね。
※ MySQLのレプリケーションでは、以前からSSLを利用した通信の暗号化が可能です。

ログの中身を確認してみると、特定のログ以降の全てのログを読みこんだログは、
最終変更までのバイナリーログが読みこまれている事が確認出来る。
