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?
- Use the EFS-to-EFS backup solution to replicate the data to an EFS file system in another Region.
- 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.
- 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.
- 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.

  Aws backup is not replicating. Efs replication is and it's managed in that you configure it and then it does the replication - no further actions required. It's also cheapest since it's free, you just pay for data transfer and storage https://docs.aws.amazon.com/efs/latest/ug/efs-replication.html https://aws.amazon.com/blogs/aws/new-replication-for-amazon-elastic-file-system-efs/
