1. Create an EFS Backup Plan:
   • Go to the AWS Management Console and navigate to the AWS Backup service.
   • Click on “Create backup plan” and provide a name for your backup plan.
   • Select the resources you want to include in the backup plan, in this case, select the Elastic File System (EFS) that you want to backup.
   • Configure the backup settings such as backup frequency, retention period, and backup window according to your requirements.
   • Review and create the backup plan.
2. Associate EC2 Instances with the Backup Plan:
   • Go to the AWS Backup service in the AWS Management Console.
   • Click on “Protected resources” and then “Add resource”.
   • Select the EC2 instances that are using the EFS that you want to backup.
   • Associate these EC2 instances with the backup plan you created in the previous step.
3. Verify Backup Configuration:
   • Once the backup plan is created and EC2 instances are associated with it, verify that the EFS is now included in the backup plan.
   • Check the backup schedule and retention period to ensure that it meets your backup requirements.

1. Create an EFS Backup Plan:
   • Use the following AWS CLI command to create a backup plan for the EFS file system:
     Copy

     Ask AI

     aws backup create-backup-plan --backup-plan '{"BackupPlanName": "EFSBackupPlan", "BackupPlanRule": {"RuleName": "EFSBackupRule", "TargetBackupVaultName": "MyBackupVault", "ScheduleExpression": "cron(0 12 * * ? *)"}}'
     

   • In the above command, replace MyBackupVault with the name of your existing backup vault.
2. Assign EFS to Backup Plan:
   • Associate the EFS file system with the backup plan created in the previous step using the following AWS CLI command:
     Copy

     Ask AI

     aws backup associate-file-systems --backup-plan-id <BackupPlanId> --file-system-arns <EFSFileSystemARN>
     

   • Replace <BackupPlanId> with the ID of the backup plan created in step 1 and <EFSFileSystemARN> with the ARN of the EFS file system that needs to be included in the backup plan.
3. Verify Backup Plan:
   • Check the backup plan to ensure that the EFS file system is included in the backup schedule using the following AWS CLI command:
     Copy

     Ask AI

     aws backup get-backup-plan --backup-plan-id <BackupPlanId>
     

   • Verify that the EFS file system is listed under the resources included in the backup plan.

1. Import necessary libraries: First, you need to import the required Python libraries to interact with AWS services. You can use the boto3 library for this purpose.

import boto3

2. Initialize AWS client: Create an AWS client for the EC2 service using boto3.

ec2_client = boto3.client('ec2')

3. Get EFS file system ID: Retrieve the EFS file system ID that needs to be included in the backup plan. You can either provide this ID as input or fetch it programmatically.

efs_file_system_id = 'fs-12345678'  # Replace with your EFS file system ID

4. Create a backup plan: Define a backup plan that includes the EFS file system for backup. You can specify the backup schedule, retention policy, etc., as per your requirements.

backup_client = boto3.client('backup')

response = backup_client.create_backup_plan(
    BackupPlan={
        'BackupPlanName': 'EFS-Backup-Plan',
        'Rules': [
            {
                'RuleName': 'EFS-Backup-Rule',
                'TargetBackupVaultName': 'MyBackupVault',
                'ScheduleExpression': 'cron(0 0 * * ? *)',  # Daily backup at midnight
                'StartWindowMinutes': 60,
                'CompletionWindowMinutes': 60,
                'Lifecycle': {
                    'DeleteAfterDays': 30  # Retention period
                }
            }
        ]
    }
)

5. Add EFS file system to the backup plan: Associate the EFS file system with the backup plan created in the previous step.

response = backup_client.associate_file_system(
    BackupPlanId=response['BackupPlanId'],
    FileSystemId=efs_file_system_id
)

6. Verify the backup plan: You can verify the backup plan settings and ensure that the EFS file system is included in the plan.

response = backup_client.get_backup_plan(
    BackupPlanId=response['BackupPlanId']
)

print(response)
