EC2インスタンスのバックアップ

AmazonS3上にEC2のイメージファイルを保存 †

• 事前にAmazonS3にてBucket（ストレージ）を作成（Bucket Name: yujidev-backup）

• インスタンス起動時に作成した秘密鍵とX509証明書をEC2上へアップロード

$ scp -i SSH用プライベート鍵 秘密鍵 ec2-user@ec2-54-248-20-228.ap-northeast-1.compute.amazonaws.com

$ scp -i プライベート鍵 X509証明書 ec2-user@ec2-54-248-20-228.ap-northeast-1.compute.amazonaws.com

• 「ec2-bundle-vol -d」コマンドを使用して保存先を指定して（/mnt/backup[yyyymmdd]とする）イメージファイルを作成　※口座番号はAWS>>セキュリティ証明書 https://portal.aws.amazon.com/gp/aws/securityCredentials より取得可能

# mkdir /mnt
# mkdir /mnt/backup[yyyymmdd]
# ec2-bundle-vol -d /mnt/backup[yyyymmdd] --privatekey 秘密鍵 --cert X509証明書 --user 口座番号
