Which backup methodology should the database specialist use to MINIMIZE management overhead?
Install the AWS CLI on an Amazon EC2 instance. Write a CLI command that creates a backup of the DynamoDB table. Create a scheduled job or task that runs the command on a nightly basis.
Create an AWS Lambda function that creates a backup of the DynamoDB table. Create an Amazon CloudWatch Events rule that runs the Lambda function on a nightly basis.
Create a backup plan using AWS Backup, specify a backup frequency of every 24 hours, and give the plan a nightly backup window.
Configure DynamoDB backup and restore for an on-demand backup frequency of every 24 hours.
Explanations:
Requires manual setup of AWS CLI on an EC2 instance and scheduling, leading to higher management overhead.
Lambda and CloudWatch Events are feasible but require development and management, which adds overhead.
AWS Backup provides an automated, fully managed solution for backups with minimal overhead.
DynamoDB on-demand backups do not support automatic nightly scheduling, leading to more management.
As I understand it, the answer is:
Create a backup plan using AWS Backup, specify a backup frequency of every 24 hours, and give the plan a nightly backup window.
