### Description:

Amazon Elastic File System (Amazon EFS) provides simple, scalable, highly available, and highly durable shared file systems in the cloud. The file systems you create using Amazon EFS are elastic, allowing them to grow and shrink automatically as you add and remove data. They can grow in size to petabytes, distributing data across an unconstrained number of storage servers in multiple Availability Zones (AZs).

### Impact:

Implement a backup solution to recover from unintended changes or deletions to file systems.

  

### Default value:

By default, EFS will enable automatic backups.

  

### Audit:

-   Login to AWS management console
    
-   Go to EFS service at [https://console.aws.amazon.com/efs/](https://console.aws.amazon.com/efs/ "https://console.aws.amazon.com/efs/")
    
-   Click on the File Systems in the left navigation pane
    
-   Select the file system you want to examine and click on view details
    
-   Under Automatic backups see whether it’s enabled or disabled

    If you notice Backups are Disabled follow the implementation steps to enable.
    

  

**Via CLI:**

aws efs describe-backup-policy --file-system-id <value>
