Deploying your AWS DataSync agent in an AWS Region

The following guidance can help with common scenarios if you deploy an AWS DataSync agent in an AWS Region. If you don't have an agent yet, see Deploy your agent on Amazon EC2.

Transferring data from a cloud file system to another cloud file system or Amazon S3

To transfer data between AWS accounts, or from a cloud file system, the DataSync agent must be located in the same AWS Region and AWS account where the source file system resides. This type of transfer includes the following:

  • Transfers between Amazon EFS or FSx for Windows File Server file systems to AWS storage in a different AWS account.

  • Transfers from self-managed file systems to AWS storage services.

Important

Deploy your agent such that it doesn't require network traffic between Availability Zones (to avoid charges for such traffic).

  • To access your Amazon EFS or 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.

For example, the following diagram shows a high-level view of the DataSync architecture for transferring data from in-cloud Network File System (NFS) to in-cloud NFS or Amazon S3.

Note

Deploy the agent in the AWS Region and AWS account where the source file system resides.

  • When you're copying between two Amazon EFS file systems in different AWS accounts, we recommend that you use the NFS (source) to EFS (destination) transfer.

  • When you're copying between two Amazon FSx file systems in different AWS accounts, we recommend that you use the Server Message Block (SMB) (source) to Amazon FSx (destination) transfer.

Transferring data from Amazon S3 to AWS file systems

The following diagram provides a high-level view of the DataSync architecture for transferring data from Amazon S3 to an AWS file system, such as Amazon EFS or Amazon FSx. You can use this architecture to transfer data from one AWS account to another, or to transfer data from Amazon S3 to a self-managed in-cloud file system.
