Exam AWS Certified Solutions Architect - Associate SAA-C03 topic 1 question 259 discussion

A. suggests using AWS Backup, a centralized backup management service, to retain RDS backups. A backup vault is created, and a backup plan is defined with a daily schedule and a 2-year retention period for backups. RDS DB instances are assigned to this backup plan. B. it does not address the requirement for consistent and restorable backups. Snapshots are point-in-time backups and may not provide the desired level of consistency. C. it is not designed to provide the backup and restore functionality required for databases. It does not ensure the backups are consistent or provide an easy restore mechanism. D. it does not address the requirement for daily backups and retention of consistent backups. It focuses more on replication and change data capture rather than backup and restore.

The solution architect should recommend option B - Configure a backup window for the RDS DB instances for daily snapshots. Assign a snapshot retention policy of 2 years to each RDS DB instance. Use Amazon Data Lifecycle Manager (Amazon DLM) to schedule snapshot deletions. This meets the requirements of: Retaining daily backups for a minimum of 2 years. The daily snapshots captured within the backup window provide consistent, restorable backups on a daily basis. Assigning a snapshot retention policy of 2 years ensures the snapshots are retained for the required period. Using Amazon DLM allows automatically deleting snapshots older than 2 years to comply with the retention period in a cost-effective manner without manual administration. The other option of using AWS Backup vault is not as suitable since it has limitations such as 35 day maximum retention for automated backups. Option B provides a native RDS solution capable of meeting the long term 2 year retention requirements.

Here's why Option B is the best choice: Backup Window: Configuring a backup window for daily snapshots ensures that consistent backups are taken at the specified time each day. This helps maintain data integrity and consistency. Snapshot Retention Policy: Assigning a snapshot retention policy of 2 years to each RDS DB instance ensures that the backups are retained for the required duration. Amazon Data Lifecycle Manager (Amazon DLM): Amazon DLM can be used to automate the management of EBS snapshots, including RDS snapshots. You can configure Amazon DLM to schedule snapshot deletions, making it easier to manage the retention policy without manual intervention. Option A (AWS Backup) is primarily used for managing backups of resources that may not have built-in backup capabilities, but for Amazon RDS, it's better to use the built-in snapshot capabilities and Amazon DLM for snapshot retention.

Create a backup vault in AWS Backup to retain RDS backups. Create a new backup plan with a daily schedule and an expiration period of 2 years after creation. Assign the RDS DB instances to the backup plan.

Backups work with EBS, FSX, RDS. Its managed & can has vault option for more better control over backup retention

Why not B?

A is correct

Why not D? Creating tasks for ongoing replication using AWS DMS: You can create an AWS DMS task that captures ongoing changes from the source data store. You can do this capture while you are migrating your data. You can also create a task that captures ongoing changes after you complete your initial (full-load) migration to a supported target data store. This process is called ongoing replication or change data capture (CDC). AWS DMS uses this process when replicating ongoing changes from a source data store.
