How AWS EFS Works with Backup?
Last Updated :
23 Jul, 2025
Amazon Elastic File System (EFS) is a scalable, managed Network File System (NFS) that provides shared storage for Amazon Web Services (AWS) resources such as Amazon EC2 instances and containers. In this article, we'll explore how EFS works with backup, ensuring the safety and recoverability of your data
What is AWS EFS?
AWS EFS, it stands for Amazon Elastic File System. It is a scalable and fully managed file storage service that provides simple and scalable file storage for use with AWS Cloud Services and On-premises. It facilitates to easily create and manage the file systems quickly and easily. It is deals for workloads that requires the sharing access to data, web serving and big data analytics.
How AWS EFS Works With Backup and Restore?
AWS EFS provides efficient backups through its seamless integration with AWS Backups and performing restore operations. Through this users can create the backup plans with specifying the backup frequency, retention policies and life cycle management. AWS Backups automate the process of creating and managing the backups ensuring the data integrity and compliance.
What Are AWS EFS Snapshots?
AWS EFS snapshots are point-in-time backups of your file system data that is stored in Amaozn Elastic File System (EFS). They captures the state of your file system at a specific moments enabling you to create consistent backups for data protection and disaster recovery purposes.
What Are EFS Storage Classes?
Amazon EFS provides 2 types of EFS Storage Classes based on the performances and latency factors. They are as follows:
1. Standard: IT will be ideal for frequently accessed data that requiring high-performance and low-latency access.
2. Infrequent Access (IA): It is suitable for less frequently accessed data on offiering cost saving with slightly higher latency.
Step 1: First create AWS EFS from the EFS page. On the EFS page click on Create File System.

- On Backup page click on create backup plan, now the AWS EFS has successfully created.
How to Create AWS Backup For AWS EFS? A Step-By-Step Guide
Step 1: Now on create AWS EFS Backup on specifying settings as below . You can select template as per your requirement or you can configure backup plan from scratch .
.png)
- After clicking on the create backup plan, we will be directed for defining the specifications as follows. Choose the specifications as needed.

Step 4: Now select specific resource type as "EFS" under EFS select your EFS from dropdown .
.png)
- Leave other options as default or specify as per your requirement . Then Click assign .
- Once this is done the EFS is associated with backup plan . It will be backup daily for retention period of 35 days as we have specified . You can configure backup plans as your requirement for EFS .
How to Delete EFS Backups? A Step-By-Step Guide
The following are the steps for deleting the Amazon EFS Backups:
Step 1: Access AWS Backup Console
Step 2: Select Backup Vault
- Once landed to AWS Backup Service, choose the backup vault that contains the EFS backups you want to delete.
Step 3: View Backup Jobs
- Locate the backup job that is associated with the EFS file system you wishing to delete.
Step 4: Delete Backup Job
- In the backup jobs, select the backup jobs that you wish to delete and choose the delete option to delete. Confirm once with backup jobs you want delete by entering delete on showing box.
Step 5: Verify Deletion
- After deleting the backup jobs ensure whether they are deleted or not from the vault by viewing in the AWS Backup jobs.
How to do EFS-to-EFS Backups? A Step-By-Step Guide
The following are the steps to perform EFS to EFS backups:
Step 1: Setup Source And Destination EFS file systems
Firstly ensure you have both the source and destination EFS created and accessable in your AWS Account.
Step 2: Use Data Sync
- Now, Try on using AWS Service such as AWS Data Sync a service that is designed for fast and secure data transfers between EFS systems.
- It Configures the DataSync tasks to sync data from the source EFS file system to the destination EFS file system.
Step 3: Schedule Sync Tasks
- Configuring the DataSync, set up a schedule for DataSync tasks to regularly sync data between source and destination EFS file systems to ensures the backups to be up to date.
Step 4: Monitor And Manage
- Regularly monitor the DataSync tasks to ensure smoothly running and resolve troubleshooting issues if any arise. Adjust the scheduling or configurations as needed to optimize the performance and resource usage.
How To Restore an Amazon EFS file system using AWS Backup? A Step-By-Step Guide
The following are the steps used to restore an Amazon EFS file system using AWS Backup:
Step 1: Access AWS Backup Console
- Firstly login your AWS Management Console with your credentials and navigate to your AWS Backup Service.
Step 2: Select Recovery Points
- Choose the backup vault that contains the desired looking EFS file system backups.
- Select the specific recovery point (backup) you want to restore from.
Step 3: Initate Restore Job
- Click on the "Restore" option and provide the details such as the target region and file system settings for restoring process.
Step 4: Review and Confirm
- Review the restoration details once and then confirm it to inititate for restoring the EFS file system process.
Step 5: Monitor Progress
- Ensure to monitor the restoring progress of the job to an Amazon File system in the AWS Backup Console. Once completing the process verify the successful restoration of the EFS system.
What are Automatic Backups?
Automatic Backups refers to the process of automating the backups and managing them without any manual interventions. These backups are typically shceduled at regular intervals for ensuring data protection and recovery in case of data disastery cases. Services like AWS Backup offers the automation of backup solutions for various AWS resources for simplifying the backup management and ensuring the data resilience with minimal efforts from the user.
How Turn Automatic Backups On or Off For Existing File Systems?
The following the steps for turn on or off the Automatic Backups for Existing File Systems:

Step 3: Modify the Backup Settings
- In that configuration of selecting EFS service, under the backup tab, Customize the Automatic Backups settings to turn on or off according to the preference.
Concurrent Backups
Concurrent Backups refers to the capability of a system to execute multiple backup processes simultaneously. This feature facilitates with more efficient use of resources and faster backup completion times. It is especially used in environments with large datasets or high backup demands.
Backup Performance is a measure of speed and efficiency in performing the backup operations. It includes the factors such as backup speed, throughput and resource utilization. Optimization of backup performance provides timely and reliable data protection which minimize the impact on system resources and operations.
