AWS DataSync
User Guide


Activates an AWS DataSync agent that you have deployed on your host. The activation process associates your agent with your account. In the activation process, you specify information such as the AWS Region that you want to activate the agent in. You activate the agent in the AWS Region where your target locations (in Amazon S3 or Amazon EFS) reside. Your tasks are created in this AWS Region.

You can use an agent for more than one location. If a task uses multiple agents, all of them need to have status AVAILABLE for the task to run. If you use multiple agents for a source location, the status of all the agents must be AVAILABLE for the task to run.

For more information, see Activating an Agent in the AWS DataSync User Guide.

Agents are automatically updated by AWS on a regular basis, using a mechanism that ensures minimal interruption to your tasks.

Request Syntax

{ "ActivationKey": "string", "AgentName": "string", "Tags": [ { "Key": "string", "Value": "string" } ] }

Request Parameters

For information about the parameters that are common to all actions, see Common Parameters.

The request accepts the following data in JSON format.


Your agent activation key. You can get the activation key either by sending an HTTP GET request with redirects that enable you to get the agent IP address (port 80). Alternatively, you can get it from the AWS DataSync console.

The redirect URL returned in the response provides you the activation key for your agent in the query string parameter activationKey. It might also include other activation-related parameters; however, these are merely defaults. The arguments you pass to this API call determine the actual configuration of your agent.
