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

infrastructure.
