Does Amazon have anything like EFS, only with redundancy?

hbquikcomjamesl asked:

We have an application on AWS, that uses a MySQL database and an EFS file store. We’ve got the database set up with multi-AZ redundancy, but I don’t see anything similar for the EFS file store.

Is there a way to get a similar redundancy and failover capability for EFS? Or for something else that an EC2 Linux instance can mount as a file system?

My answer:

Amazon EFS already supports multi-AZ availability. You need only to choose Regional availability when creating the filesystem. This is the default setting.

EFS create filesystem with Regional availability

You can see whether the EFS filesystem is regional by checking the Availability Zone column in the filesystem listing in the AWS console.
