How AWS Backup works with other AWS services

Some AWS services offer their own backup features, including Amazon Elastic Block Store (Amazon EBS) snapshots, Amazon Relational Database Service (Amazon RDS) snapshots, Amazon DynamoDB backups, AWS Storage Gateway snapshots, and others. These features are available to you independent of whether you use AWS Backup.

To configure AWS Backup to centrally manage backups of supported services, you must opt-in to managing that service with AWS Backup, initiate your backups using AWS Backup, and store your backups in backup vaults. However, the backups other AWS services create are not available for central governance through AWS Backup.

Opt-in to managing services with AWS Backup

When new AWS services become available, you must enable AWS Backup to use those services. If you try to create an on-demand backup or backup plan using resources from a service that is not enabled, you receive an error message and cannot complete the process.


Service opt-in settings are Region-specific. If you change the AWS Region that you're using, you must reconfigure the services that you use with AWS Backup.

To configure the services used with AWS Backup

  1. Open the AWS Backup console at

  2. In the navigation pane, choose Settings.

  3. On the Service opt-in page, choose Configure resources. Use the toggle switches to enable or disable the services used with AWS Backup.

  4. Choose Confirm when your services are configured.


Backups created with AWS Backup cannot be deleted using APIs that belong to the backed-up resource. For information about deleting recovery points using the AWS Backup API, see DeleteRecoveryPoint.

Working with Amazon FSx file systems

AWS Backup supports backing up and restoring Amazon FSx file systems. Amazon FSx provides fully managed third-party file systems with the native compatibility and feature sets for workloads, such as Microsoft Windows–based storage, high performance computing, machine learning, and electronic design automation.

Amazon FSx supports two file system types: Lustre and Windows File Server. You can back up any Amazon FSx for Windows File Server file system and any Amazon FSx for Lustre file system that has persistent storage and is not linked to a data repository such as Amazon S3. AWS Backup uses the built-in backup functionality of Amazon FSx. So backups taken from the AWS Backup console have the same level of file system consistency and performance, and the same restore options as backups that are taken through the Amazon FSx console.

If you use AWS Backup to manage these backups, you gain additional functionality, such as unlimited retention options, and the ability to create scheduled backups as frequently as every hour. In addition, AWS Backup retains your backups even after the source file system is deleted. This protects against accidental or malicious deletion.

Use AWS Backup to protect Amazon FSx file systems if you want to configure backup policies and monitor backup tasks from a central backup console that also extends support for other AWS services.

For detailed information about Amazon FSx file systems, see the Amazon FSx documentation.

Working with Amazon EC2

Using AWS Backup, you can schedule or perform on-demand backup jobs that include entire EC2 instances and Windows applications running on Amazon EC2, along with associated configuration data. This limits the need for you to interact with the storage (Amazon EBS) volume. Similarly, you can restore an entire Amazon EC2 instance from a single recovery point. A backup job can only have one resource. So you can have a job to back up an EC2 instance, and it will back up the root volume, all data volumes, and the associated instance configurations.

AWS Backup does not reboot EC2 instances at any time.

Backing Up Amazon EC2 Resources

When backing up an Amazon EC2 instance, AWS Backup takes a snapshot of the root Amazon EBS storage volume, the launch configurations, and all associated EBS volumes. AWS Backup stores certain configuration parameters of the EC2 instance, including instance type, security groups, Amazon VPC, monitoring configuration, and tags. The backup data is stored as an Amazon EBS volume-backed Amazon Machine Image (AMI).

You can also back up and restore your VSS-enabled Microsoft Windows applications. You can schedule application-consistent backups, define lifecycle policies, and perform consistent restores as part of an on-demand backup or a scheduled backup plan. For more information, see Creating Windows VSS backups.

AWS Backup does not back up the following:

  • Configuration of the Elastic Inference accelerator, if it is attached to the instance.

  • User data used when the instance was launched.


For all instance types, only Amazon EBS backed EC2 instances are supported. Ephemeral storage instances (that is, instance store-backed instances) are not supported.

AWS Backup can encrypt EBS snapshots associated with an Amazon EC2 backup. This is similar to how it encrypts EBS snapshots. AWS Backup uses the same encryption applied on the underlying EBS volumes when creating a snapshot of the Amazon EC2 AMI, and the configuration parameters of the original instance are persisted in the restore metadata.

A snapshot derives its encryption from the volume as you have defined, and the same encryption is applied to the corresponding snapshots. EBS snapshots of a copied AMI will always be encrypted. If you use a KMS key during the copy, the key will be applied. If you don't use a KMS key, a default KMS key is applied.

For detailed information about Amazon EC2, see What is Amazon EC2? in the Amazon EC2 User Guide for Windows Instances.

Working with Amazon EFS

AWS Backup currently supports Amazon Elastic File System (Amazon EFS).

For detailed information about Amazon EFS file systems, see What is Amazon Elastic File System? in the Amazon Elastic File System User Guide.

Working with Amazon DynamoDB

AWS Backup currently supports Amazon DynamoDB (DynamoDB).

For detailed information about DynamoDB, see What is Amazon DynamoDB? in the Amazon DynamoDB Developer Guide.

Working with Amazon EBS

AWS Backup currently supports Amazon Elastic Block Store (Amazon EBS) volumes.

For detailed information about Amazon EBS volumes, see What is Amazon Elastic Block Store (Amazon EBS)? in the Amazon EC2 User Guide for Linux Instances.

For more information, see Creating an Amazon EBS Volume in the Amazon EC2 User Guide for Linux Instances.

Working with Amazon RDS and Amazon Aurora

AWS Backup currently supports Amazon RDS database engines and Aurora clusters.

For more information about Amazon RDS, see What is Amazon Relational Database Service? in the Amazon RDS User Guide.

For detailed information about Aurora, see What is Amazon Aurora? in the Amazon Aurora User Guide.


If you initiate a backup job from the Amazon RDS console, this can conflict with an Aurora clusters backup job, causing the error Backup job expired before completion. If this occurs, configure a longer backup window in AWS Backup.

Working with AWS Storage Gateway

Amazon EBS snapshots can be restored as AWS Storage Gateway volumes.

For detailed information about AWS Storage Gateway, see What is AWS Storage Gateway? in the AWS Storage Gateway User Guide.
