They have chosen to use RDS Oracle as the database.
Which backup architecture will meet these requirements?

  • A. Backup RDS using automated daily DB backups. Backup the EC2 instances using AMIs and supplement with file-level backup to S3 using traditional enterprise backup software to provide file level restore.
  • B. Backup RDS using a Multi-AZ Deployment. Backup the EC2 instances using Amis, and supplement by copying file system data to S3 to provide file level restore.
  • C. Backup RDS using automated daily DB backups. Backup the EC2 instances using EBS snapshots and supplement with file-level backups to Amazon Glacier using traditional enterprise backup software to provide file level restore.
  • D. Backup RDS database to S3 using Oracle RMAN. Backup the EC2 instances using Amis, and supplement with EBS snapshots for individual volume restore.

why no Glacier? Expedited retrievals in Glacier is within 1-5 minutes.

If the question does not specify the Glacier type, we need to assume it's "classic" Glacier with 12 hours retrieval time

Selected Answer: D
D. RMAN is supported at RDS (for Oracle) -> restore individual files from DB, should meet RTO =2h. https://docs.aws.amazon.com/AmazonRDS/latest/UserGuide/Appendix.Oracle.CommonDBATasks.RMAN.html AMIs will provide a quick recovery of the EC2/server. EBS snapshots will provide disk recovery functionality.

AWS RDS oracle supports RMAN https://aws.amazon.com/blogs/database/automate-amazon-rds-backups-using-the-oracle-rman-utility-and-upload-backup-files-to-amazon-s3/ Given 2 hour Restore objective, D is a viable option.

Selected Answer: C
C is correct. A) Backup the EC2 instances using AMIs is nonsense. The only reasonable way to back up your instance is snapshots using DLM. B) Multi-AZ deployment is not from a backup opera at all. It's more of HA strategy. D) For using Oracle RMAN the one have to OS level access to DB instance. Which's not the case with RDS.
