You are a development lead, and your team has maintained an emailing service for the company’s major applications. The emailing service is deployed on-premises with several RDS on VMware databases to store users’ metadata. There is no plan to migrate the on-premises RDS databases to AWS RDS. However, you need an appropriate approach to backup the databases to AWS so that the database can be quickly restored. Which steps should you take to fulfill this requirement? (Select THREE)

Answer options:

A.Specify an automated backup every day to store the snapshot to the S3 bucket so that the backup has high availability and durability.
B.Configure a read-replica in a different region from the one that the RDS on VMware instance connects to.
C.Create an automated backup schedule in RDS and save the daily snapshots to AWS Glacier for long-term backup.
D.Create a read-replica in the same region for disaster recovery as long as the region supports RDS.
E.Create a manual backup of the on-premise database if needed.

Correct Answer – A, D, E
When using Amazon RDS on VMware, it also makes it very easy to take advantage of the AWS scale for disaster recovery, cloud backups, and read replica scaling. The same RDS console, APIs, or CLI can be used to manage RDS databases running on VMware or RDS databases running on AWS. Refer to https://aws.amazon.com/rds/vmware/ on how to do the hybrid cloud backups and scaling.
Option A is CORRECT: Because the Amazon RDS on VMware backup/restore system enables point-in-time restore for all supported engines and allows you to specify an automated backup retention period of up to 35 days.
Option B is incorrect: Because for Amazon RDS on VMware, you can only create a read replica in the same region as the source DB instance. Details please check https://aws.amazon.com/rds/vmware/faqs/.
Option C is incorrect: Because AWS Glacier is unsuitable for a quick restore.
Option D is CORRECT: Because the read replica can be created in the same region. RDS on VMware is available in AWS US East (Northern Virginia) Region. References can be found in https://aws.amazon.com/rds/vmware/faqs/. Please note that a Read Replica can be promoted if the database needs to be restored in AWS RDS. 
Option E is CORRECT: Because this method can create a manual snapshot in AWS, if needed.
