Exam AWS Certified Solutions Architect - Associate SAA-C03 topic 1 question 178 discussion

Using AWS Backup to copy EC2 and RDS backups to the separate Region is the solution that meets the requirements with the least operational overhead. AWS Backup simplifies the backup process and automates the copying of backups to another Region, reducing the manual effort and operational complexity involved in managing separate backup processes for EC2 instances and RDS databases. Option B is incorrect because Amazon Data Lifecycle Manager (Amazon DLM) is not designed for directly copying RDS backups to a separate region. Option C is incorrect because creating Amazon Machine Images (AMIs) and read replicas adds complexity and operational overhead compared to a dedicated backup solution. Option D is incorrect because using Amazon EBS snapshots, RDS snapshots, and S3 Cross-Region Replication (CRR) involves multiple manual steps and additional configuration, increasing complexity.

Cross-Region backup Using AWS Backup, you can copy backups to multiple different AWS Regions on demand or automatically as part of a scheduled backup plan. Cross-Region backup is particularly valuable if you have business continuity or compliance requirements to store backups a minimum distance away from your production data. https://docs.aws.amazon.com/aws-backup/latest/devguide/whatisbackup.html

AWS Backups are the most suitable here.

A for sure

The easiest way to backup an EC2 instance and RDS Database would be to use AWS Backup. With AWS Backup you can: Create a backup plan and select both the EC2 volume and RDS database for backup. Choose a backup schedule that meets your requirements, such as daily or weekly backups. AWS Backup will automatically take snapshots of the EC2 volume and backups of the RDS database as per the configured schedule. The backups will be stored in S3 for long term retention based on your backup plan configuration.

AWS Backup provides a fully managed, centralized backup service across AWS services. It can be configured to automatically copy backups across Regions. This requires minimal operational overhead compared to the other options:

D would have been a great option but the questions requires less mannual effort. So, A is better.

A is correct

Option B, using Amazon Data Lifecycle Manager (Amazon DLM) to copy EC2 backups and RDS backups to the separate Region, would require more operational overhead because DLM is primarily designed for managing the lifecycle of Amazon EBS snapshots, and would require additional configuration to manage RDS backups. Option C, creating AMIs of the EC2 instances and read replicas of the RDS DB instance in the separate Region, would require more manual effort to manage the backup and disaster recovery process, as it requires manual creation and management of AMIs and read replicas.

Option A, using AWS Backup to copy EC2 backups and RDS backups to the separate region, is the correct answer for the given scenario. Using AWS Backup is a simple and efficient way to backup EC2 instances and RDS databases to a separate region. It requires minimal operational overhead and can be easily managed through the AWS Backup console or API. AWS Backup can also provide automated scheduling and retention management for backups, which can help ensure that backups are always available and up to date.

A is correct - you need to find a backup solution for EC2 and RDS. DLM doent work with RDS , only with snapshots.

using Amazon DLM to copy EC2 backups and RDS backups to the separate region, is not a valid solution because Amazon DLM does not support backing up data across regions.

Option B. Use Amazon Data Lifecycle Manager (Amazon DLM) to copy EC2 backups and RDS backups to the separate Region. Amazon DLM is a fully managed service that helps automate the creation and retention of Amazon EBS snapshots and RDS DB snapshots. It can be used to create and manage backup policies that specify when and how often snapshots should be created, as well as how long they should be retained. With Amazon DLM, you can easily and automatically create and manage backups of your EC2 instances and RDS DB instances in a separate Region, with minimal operational overhead.

Option A as it is fully managed service with least operational overhead

A AWS Backup is a fully managed service that handles the process of copying backups to a separate Region automatically

Ans A with least operational overhead

AWS Backup supports Supports cross-region backups
