AWS DataSync is a high-speed, online data transfer service that makes it easy to securely move your data anywhere its needed: on premises, at the edge, or in the cloud. DataSync offers simple, predictable, pay-as-you-go pricing. You pay a flat, per-gigabyte fee for the amount of data transferred between your storage locations. Tasks configured for Enhanced mode are also charged a fee per task execution. These fees cover the costs to move, verify, and synchronize your data. With DataSync, there are no upfront costs and no minimum charges.
Using AWS DataSync Discovery, you can run discovery jobs for up to 31 days and receive recommendations free of charge. DataSync Discovery keeps collected data and associated recommendations for 60 days following job completion.
Enhanced mode data transfers
Using Enhanced mode, you can transfer virtually unlimited numbers of objects between your storage locations with higher performance than Basic mode. Enhanced mode tasks optimize and streamline the data transfer process by listing, preparing, transferring, and verifying data in parallel. Enhanced mode is currently available for transfers between Amazon S3 locations only.
Basic mode data transfers
Basic mode is subject to quotas on the number of files and objects in a dataset. Basic mode sequentially prepares, transfers, and verifies files and objects in a dataset, making it slower than Enhanced mode for most workloads. Basic mode supports all DataSync location types available today.
Additional charges
When using DataSync to copy data, you are charged standard request, storage, and data transfer rates to read from and write to AWS services, such as Amazon Simple Storage Service (Amazon S3), Amazon Elastic File System (Amazon EFS), Amazon FSx for Windows File Server, Amazon FSx for Lustre, Amazon FSx for OpenZFS, Amazon FSx for NetApp ONTAP, and AWS Key Management Service (AWS KMS).
You will be billed by AWS PrivateLink for interface Amazon Virtual Private Cloud (Amazon VPC) endpoints that you create to manage and control the traffic between your agent(s) and the DataSync service over PrivateLink. Only control traffic is subject to PrivateLink charges. This includes commands from the DataSync service to the agent, such as StartTaskExecution. The files or objects transferred by DataSync are not subject to PrivateLink charges. You are also charged standard rates for Amazon CloudWatch Logs, Amazon CloudWatch Metrics, and Amazon CloudWatch Events.
Copying data to and from Amazon S3
When copying data to or from S3, you are charged standard request charges for the following S3 requests: LIST, HEAD, GET, PUT, and COPY. The exact operations performed depend upon the configuration of your DataSync task. For more information, read about evaluating S3 request costs in our documentation. Requests and storage charges can vary between S3 storage classes. You may also incur additional charges when reading and writing objects in different S3 storage classes. Read about working with Amazon S3 storage classes in our documentation.
Copying data to and from AWS Regions
When copying data from AWS to an on-premises storage system, you pay for AWS Data Transfer OUT from your source AWS Region. When copying data between Regions, you pay for Data Transfer between Regions (billed as Data Transfer OUT from your source Region to your destination Region). When copying data between AWS services using the AWS DataSync EC2 agent, you pay for Data Transfer between Regions and for Data Transfer between Availability Zones. To learn more, see Data Transfer pricing.
Using AWS DataSync Discovery
When using DataSync Discovery, you will be billed by AWS Secrets Manager for secrets created to store credentials for your on-premises storage systems, along with any Secrets Manager API calls made by DataSync to access secrets.
Enhanced mode pricing examples
The pricing examples below assume that the DataSync data transfer task has been configured for Enhanced mode to achieve higher performance, scale, and enhanced monitoring and metrics.
Example 1: Copy a 50 TB dataset from one S3 bucket to another, within the same Region, using the S3 Standard storage class
DataSync will perform a one-time copy of objects in one S3 bucket to a destination bucket in the same Region. Objects in both the source and destination buckets are created with the S3 Standard storage class. When the DataSync task executes, it will scan the existing objects in the source bucket to determine which objects should be copied. The scan process involves, at a minimum, LIST and HEAD requests on objects in each S3 bucket, as explained in the AWS DataSync documentation. Assume the source dataset contains 5 million objects.
(50 TB * 1024 GB copied using DataSync * $0.015/GB)
(5,000 S3 LIST requests * $0.005 / 1000)
(5 million S3 HEAD requests * $0.0004 / 1000)
(5 million S3 GET requests * $0.0004 / 1000)
(5 million S3 PUT requests * $0.005 / 1000)
(1 task execution * $0.55)
= $768 $0.025 $2 $2 $25 $0.55
= $797.58
Example 2: Perform a daily replication of a 5 TB dataset from one S3 bucket to another, within the same Region, using the S3 Glacier Instant Retrieval storage class
DataSync will replicate objects in one S3 bucket to a destination bucket in the same Region, using a schedule configured to run once per day. Objects in both the source and destination buckets were created with the Glacier Instant Retrieval storage class. For each daily task execution, DataSync will scan the existing objects in the source and destination buckets to determine which objects should be copied. The scan process involves, at a minimum, LIST and HEAD requests on objects in each S3 bucket, as explained in the AWS DataSync documentation. In this example, we assume a 5% change rate per day.
Cost to use DataSync for each daily replication of 5 TB of 16 MB files into Amazon S3 in the US East (Ohio) Region, assuming 4000 LIST requests in each S3 bucket, one GET per object copied, and one HEAD request per object in each S3 bucket:
Amount of data copied incrementally is 5% of 5TB = 256 GB
(256 GB copied using DataSync * $0.015/GB)
(256 GB retrieved from S3 Glacier Instant Retrieval * $0.03)
(4000 S3 LIST requests * 2 * $0.02 / 1000)
(5 TB * 1024 GB * 1024 MB / 16 MB S3 HEAD requests * 2 * $0.01 / 1000)
(256 GB * 1024 MB / 16 MB S3 GET requests * $0.01 / 1000)
(256 GB * 1024 MB / 16 MB S3 PUT requests * $0.02 / 1000)
(1 task execution per day * $0.55)
= $3.84 $7.68 $0.16 $6.55 $0.16 $0.32 $0.55
= $19.26 / day
Basic mode pricing examples
The pricing examples below assume that the DataSync data transfer task has been configured for Basic mode.
Example 1: Migrate 50 TB from on-premises storage to an empty S3 bucket using the S3 Standard storage class
Cost to use DataSync for a one-time migration of 50 TB of 16 MB files into an empty Amazon S3 bucket in the US East (Ohio) Region:
(50 TB copied into S3 * 1024 GB * $0.0125/GB) (1 S3 LIST request * $0.005 / 1000) (50 TB / 16 MB S3 PUT requests * $0.005 / 1000)
= $640 $0 $16.38
= $656.38
Example 2: Incrementally copy 10 TB from on-premises storage to an S3 bucket with 50 TB of existing data using the S3 Standard storage class
In this example, DataSync will scan the existing objects in the S3 bucket to determine which data should be copied from on premises. The scan process involves, at a minimum, LIST and HEAD requests on objects in the S3 bucket, as explained in the AWS DataSync documentation.
Cost to use DataSync for each incremental copy of 10 TB of 16 MB files into S3 in the US East (Ohio) Region, assuming 500 LIST requests and one HEAD request per object in S3:
(10 TB copied into S3 using DataSync * 1024 GB * $0.0125/GB)
(500 S3 LIST requests * $0.005 / 1000)
(50 * 1024 *1024 MB / 16 MB S3 HEAD requests * $0.0004 / 1000)
(10 * 1024 * 1024 MB / 16 MB S3 PUT requests * $0.005 / 1000)
= $128 $0 $1.31 $3.28
= $132.59
Example 3: Perform a daily replication of a 5 TB dataset from one S3 bucket to another, within the same Region, using the S3 Glacier Instant Retrieval storage class
In this example, DataSync will replicate objects in one S3 bucket to a destination bucket in the same Region. Objects in both the source and destination buckets were created with the Glacier Instant Retrieval storage class. For each daily task execution, DataSync will scan the existing objects in the source and destination buckets to determine which objects should be copied. The scan process involves, at a minimum, LIST and HEAD requests on objects in each S3 bucket, as explained in the AWS DataSync documentation. In this example, we assume a 5% change rate per day.
Cost to use DataSync for each daily replication of 5 TB of 16 MB files into Amazon S3 in the US East (Ohio) Region, assuming 4000 LIST requests in each S3 bucket, one GET per object copied, and one HEAD request per object in each S3 bucket:
Amount of data copied incrementally is 5% of 5TB = 256 GB
(256 GB copied using DataSync * $0.0125/GB)
(256 GB retrieved from S3 Glacier Instant Retrieval * $0.03)
(4000 S3 LIST requests * 2 * $0.02 / 1000)
(5 TB * 1024 GB * 1024 MB / 16 MB S3 HEAD requests * 2 * $0.01 / 1000)
(256 GB * 1024 MB / 16 MB S3 GET requests * $0.01 / 1000)
(256 GB * 1024 MB / 16 MB S3 PUT requests * $0.02 / 1000)
= $3.20 $7.68 $0.16 $6.55 $0.16 $0.32
= $18.07 / day
Example 4: Migrate 100 TB from a self-managed server to Amazon FSx for Windows File Server
Cost to migrate 100 TB from an on-premises Windows File Server to Amazon FSx, using DataSync:
(100 TB copied into Amazon FSx For Windows File Server * 1024 GB * $0.0125/GB)
= $1,280.00
Example 5: Ongoing data transfers for an in-cloud processing and data distribution workflow
Suppose you perform a daily 1 TB transfer into Amazon EFS. Your cost for 31 days will be:
(1 TB copied into EFS * 1024 GB * $0.0125/GB) * 31 days
= $396.80
Example 6: File system replication for business continuity with incremental transfers
Suppose you have a data replication job that copies a 10 TB file system into Amazon EFS in the Asia Pacific (Sydney) Region once and replicates 1 TB of changes every day. Your cost for the initial copy and the 31 following days of normal usage will be:
10 TB * 1024 GB * $0.0125/GB = $128 for the initial transfer
1 TB * 1024 GB * $0.0125/GB * 31 days for the incremental transfers
= $396.80 per month on an ongoing basis
