Creating an agent - AWS DataSync

Creating an agent

To access your self-managed storage, you first deploy and activate an AWS DataSync agent. The activation process associates your agent with your AWS account. An agent isn't required when transferring between AWS storage services within the same AWS account. To set up a data transfer between two AWS services, see Creating locations.

A DataSync agent can transfer data through public service endpoints, Federal Information Processing Standard (FIPS) endpoints, and Amazon VPC endpoints. For more information, see Creating a DataSync agent.

Note

When you configure your agent to use Amazon VPC endpoints, the data transferred between your agent and the DataSync service doesn't cross the public internet and doesn't require public IP addresses. For end-to-end instructions for this configuration, see Using AWS DataSync in a virtual private cloud.

To create an agent to read from a Network File System (NFS), Server Message Block (SMB), Hadoop Distributed File System (HDFS), or self-managed object storage source location

  1. Download the current DataSync .ova image or launch the current DataSync Amazon Machine Image (AMI) based on Amazon EC2 from the AWS DataSync console. For information about how to get the .ova image or Amazon EC2 AMI, see Create an AWS DataSync agent. For information about hardware requirements and recommended Amazon EC2 instance types, see Virtual machine requirements.

    Important

    If you are deploying your agent on Amazon EC2, deploy the agent so that it doesn't require network traffic between Availability Zones (to avoid charges for such traffic).

    • To access your Amazon EFS or Amazon FSx for Windows File Server file system, deploy the agent in an Availability Zone that has a mount target to your file system.

    • For self-managed file systems, deploy the agent in the Availability Zone where your file system resides.

    To learn more about data-transfer prices for all AWS Regions, see Amazon EC2 On-Demand pricing.

  2. Make sure that you satisfy the network-connectivity requirements for the agent. For information about network requirements, see Network requirements.

  3. Deploy the .ova image in your hypervisor, power on the hypervisor, and note the agent's IP address. Make sure that you can reach the agent on port 80. You can use the following command to check.

    nc -vz agent-ip-address 80
    Note

    The .ova default credentials are login admin, password password. You can change the password on the virtual machine (VM) local console. You don't need to log in to the VM for basic DataSync functionality. Logging in is required mainly for troubleshooting, network-specific settings, and so on.

    You log in to the agent VM local console by using your VM's hypervisor client. For information about how to use the VM local console, see Working with your DataSync agent's local console.

  4. Send an HTTP/1.1 GET request to the agent to get the activation key. You can do this by using standard Unix tools:

    • To activate an agent by using a public service endpoint, use the following command.

      curl "http://agent-ip-address/?gatewayType=SYNC&activationRegion=aws-region&no_redirect"

    • To activate an agent by using a virtual private cloud (VPC) endpoint, use the IP address of the VPC endpoint. Use the following command.

      curl "http://agent-ip-address/?gatewayType=SYNC&activationRegion=aws-region&privateLinkEndpoint=IP address of VPC endpoint&endpointType=PRIVATE_LINK&no_redirect"

      To find the correct IP address, open the Amazon VPC console at https://console.aws.amazon.com/vpc/ and choose Endpoints from the navigation pane at left. Choose the DataSync endpoint, and check Subnets list to find the private IP address that corresponds to the subnet that you chose for your VPC endpoint setup.

      For more information about VPC endpoint configuration, see step 5 in Configuring DataSync to use private IP addresses for data transfer.

    • To activate an agent using a Federal Information Processing Standard (FIPS) endpoint, specify endpointType=FIPS. Also, the activationRegion value must be set to an AWS Region within the United States. To activate a FIPS endpoint, use the following command. 

      curl "http://agent-IP-address/?gatewayType=SYNC&activationRegion=US-based-aws-region&endpointType=FIPS&no_redirect"

    This command returns an activation key similar to the one following.

    F0EFT-7FPPR-GG7MC-3I9R3-27DOH

  5. After you have the activation key, do one of the following:

    • To activate your agent using a public endpoint or FIPS endpoint, use the following command.

      aws datasync create-agent \
  --agent-name agent-name \
  --activation-key obtained-activation-key

    • To activate your agent using a VPC endpoint, use the following command.

      aws datasync create-agent \
  --agent-name agent-name \
  --vpc-endpoint-id vpc-endpoint-id \
  --subnet-arns subnet-arns \
  --security-group-arns security-group-arns \
  --activation-key obtained-activation-key

      In this command, use the following arguments:

      These commands return the ARN of the agent that you just activated. The ARN is similar to the one following.

      {
    "AgentArn": "arn:aws:datasync:us-east-1:111222333444:agent/agent-0b0addbeef44baca3”
}
      Note

      After you choose a service endpoint, you can't change it later.

After you activate the agent, it closes port 80 and the port is no longer accessible. If you can't connect to the agent after you have activated it, verify that the activation was successful by using the following command:

aws datasync list-agents
Note

Make sure that you are using the same AWS credentials throughout the whole process. Don't switch between multiple terminals where you are authenticated with different AWS credentials.
