Does AWS Backup support multiple NICs?

Hello AWS Customer,

When backing up an Amazon EC2 instance using AWS Backup, 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).[1]

An AMI includes the following:[2]

• One or more snapshots. Instance-store-backed AMIs include a template for the root volume of the instance (for example, an operating system, an application server, and applications).
• Launch permissions that control which AWS accounts can use the AMI to launch instances.
• A block device mapping that specifies the volumes to attach to the instance when it’s launched.

Please kindly note that it doesn't include network configurations like security groups, load balancers, network interfaces etc.

However, you can restore Amazon EC2 recovery points using the AWS Backup API, CLI, or SDK.[3] This option allows you to restore all 38 parameters, including the 22 parameters that are not customizable on the console. The Amazon EC2 API Reference[4] lists all 38 parameters. These parameters also include Network Interfaces.

Hope you will find this information useful.

I hope you are always healthy and have a nice day.

This is an example of running a restore job for an EC2 instance with multiple ENIs attached via AWS CLI.

$ aws backup start-restore-job --recovery-point-arn "arn:aws:ec2:us-west-2::image/ami-xxxxxxxxxxxxxxxxx" \
  --iam-role-arn "arn:aws:iam::123456789012:role/service-role/AWSBackupDefaultServiceRole" \
  --metadata file://metadata.json  
{
    "RestoreJobId": "XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX"
}

metadata.json contains the following parameters.

{
    "VpcId": "vpc-xxxxxxxxxxxxxxxxx",
    "Monitoring": "{\"State\":\"disabled\"}",
    "CapacityReservationSpecification": "{\"CapacityReservationPreference\":\"open\"}",
    "InstanceInitiatedShutdownBehavior": "stop",
