Topic: AWS Certified Solutions Architect - Associate SAA-C03 topic 1 question 842

A company runs an application on several Amazon EC2 instances that store persistent data on an Amazon Elastic File System (Amazon EFS) file system. The company needs to replicate the data to another AWS Region by using an AWS managed service solution.

Which solution will meet these requirements MOST cost-effectively?

A.
Use the EFS-to-EFS backup solution to replicate the data to an EFS file system in another Region.
B.
Run a nightly script to copy data from the EFS file system to an Amazon S3 bucket. Enable S3 Cross-Region Replication on the S3 bucket.
C.
Create a VPC in another Region. Establish a cross-Region VPC peer. Run a nightly rsync to copy data from the original Region to the new Region.
D.
Use AWS Backup to create a backup plan with a rule that takes a daily backup and replicates it to another Region. Assign the EFS file system resource to the backup plan.

NOTA: EFS-to-EFS backup: You must deploy this solution in the same AWS Region as your source Amazon EFS Folesystem
Not B, C: Not a managed AWS Solution
D: AWS backup will do the job, and is managed service.

To me "an AWS managed service solution" automatically translates to AWS Backup.
...Can't say if this is cheaper than EFS replication tho.

To replicate data from an Amazon Elastic File System (EFS) file system to another AWS Region, the MOST cost-effective solution would be to use EFS Replication. Here’s why:

EFS Replication:
EFS Replication allows you to natively create a copy of your file system in an AWS Region or Availability Zone (AZ) of your choice.
It automatically and transparently copies your data from the source file system to the destination, maintaining an RPO (Recovery Point Objective) of 15 minutes for most file systems.
This solution is specifically designed for replicating EFS data across Regions, ensuring data resilience and protection.
There are no additional costs for using replication failback, and you pay for the usual replication and file system changes as described in Amazon EFS pricing12.
EFS Replication is available in all AWS Regions where EFS is available1.

But it is not a managed service
