AWS Route 53 Backup Solution

Overview

This repository contains an AWS Cloud Development Kit (CDK) application for backing up AWS Route 53 zone records. As of today (April 2024) AWS does not provide a native backup service for Route 53, making it essential to have a custom solution to safeguard DNS records. This CDK application automatically provisions resources to back up Route 53 zones to an S3 bucket, scheduling backups to occur every day. For more detail please refer to my blog.

Prerequisites

Before you can deploy this application, ensure you have the following installed:

• Node.js and NPM
• AWS CLI
• Python 3.x and pip
• AWS CDK

Setup and Deployment

1. Clone the repository:

   git clone https://github.com/iut62elec/AWS-Route53-Backup-Solution.git
   cd AWS-Route53-Backup-Solution
   

2. Configure your AWS profile (replace xxx with your profile name):

   export AWS_PROFILE=xxx

3. Set up a Python virtual environment and install AWS CDK and Node.js version 18 and the required Python libraries:

   python3.11 -m venv .venv
   source .venv/bin/activate
   npm install -g aws-cdk@latest
   npm update -g aws-cdk
   nvm install 18
   nvm use 18
   pip install --upgrade pip
   pip install aws-cdk.aws-s3 aws-cdk.aws-lambda aws-cdk.aws-events aws-cdk.aws-events-targets aws-cdk.aws-iam
   

4. Bootstrap CDK (replace aws://xxx/us-east-1 with your AWS account and region) and deploy the stack:

   cdk bootstrap aws://xxx/us-east-1
   cdk deploy
   

Application Components

1. S3 Bucket: Stores the Route 53 zone backups.
2. Lambda Function: Executes the backup process every day, writing the zone records to the S3 bucket.
3. IAM Roles: Ensures the Lambda function has necessary permissions to access Route 53 and S3.
4. EventBridge Rule: Triggers the Lambda function on a scheduled basis.

Removing the Solution

Run the following command in your terminal where the CDK project is initialized:

cdk destroy
