Taking Backup of Dynamodb table and restoring it using amplify.

0

In my amplify project, I want to be production ready. So that I want to take backup of dynamodb tables and for rollback I want to restore them. As I have read from this documentation, https://docs.aws.amazon.com/amazondynamodb/latest/developerguide/GettingStartedBackupsAWS.html the restoration does not allow in the same table. And if i delete the table and restore with the same table name, the amplify will be meshed up. Since, all the resources are build from the amplify. So, what may be the best option and how can it be done. Thank you in advance. Tech used: aws-amplify, node js, aws-appsync, dynamodb, awscloudformation.

When working with DynamoDB tables in an Amplify project, ensuring that you have a reliable backup and restore strategy is crucial for production readiness. Here's a recommended approach to handle backups and restores in your Amplify project:

1)Export Data from DynamoDB Table:
    Periodically export your DynamoDB table data to an S3 bucket. You can use tools like AWS Data Pipeline, AWS Glue, or write a custom script using AWS SDK for Node.js to export the data to S3. This will create backups of your DynamoDB table in a structured format.

2)Automate Backup Process:
    Set up automated scripts or AWS services (e.g., AWS Lambda functions triggered by CloudWatch Events) to regularly perform exports to S3. This ensures that your backups are up-to-date and consistent.

3)Version Control Schema Changes:
    Utilize a version control system like Git to manage changes to your Amplify project's schema. This allows you to track changes, revert if necessary, and maintain consistency across your infrastructure.

4)Handle Rollback with CloudFormation Stacks:
    Instead of directly deleting and restoring DynamoDB tables, consider using CloudFormation stacks managed by Amplify. When you need to rollback, you can revert to a previous version of your CloudFormation stack that defines the DynamoDB table. This ensures that all related resources (such as Amplify resources) remain intact and consistent.

5) Test Backup and Restore Procedures: Regularly test your backup and restore procedures in a non-production environment to ensure they work as expected. This helps identify any potential issues or gaps in your backup strategy before they impact your production environment.

6)Monitor and Alerting:
    Implement monitoring and alerting for your backup and restore processes to detect failures or issues proactively. Services like AWS CloudWatch can be used to monitor the health and performance of your backup infrastructure.

By following these steps, you can establish a robust backup and restore strategy for your DynamoDB tables in an Amplify project while ensuring the integrity and consistency of your application resources.
