How do I transfer data from AWS to Wasabi using AWS DataSync?

In August 2023, AWS announced that their DataSync file movement and discovery service would support the ability to transfer data to and from AWS to other compatible cloud services such as Wasabi. While there are many ways to configure AWS DataSync using different source types and agent configurations, for the purposes of this guide we will be focusing on using an AWS S3 bucket as the source for your data movement, a Wasabi S3 bucket as the destination, and an EC2 instance to host the DataSync agent.

Please note: Migrating data across cloud services will incur separate charges from AWS for utilizing their DataSync service, along with any EC2-related and S3 API call charges. It is the responsibility of the customer following this guide to pay for these charges. For more information on charges from AWS, please review their pricing guide here.

Also note that an on-premise DataSync location to any non-AWS file storage destination (such as Wasabi) is not a supported configuration.

In order to transfer data between cloud services, we need to first set up and configure a few items in your Wasabi and AWS accounts.

In your Wasabi account, we need to have the following configured:

  • A Wasabi S3 bucket
  • An IAM user with permissions to write to your Wasabi bucket

In your AWS account, we need to configure:

  • A DataSync Agent running on an EC2 instance
  • A DataSync Task
  • An AWS S3 bucket
  • An IAM role configured to work with your DataSync Task and S3 source bucket
  • Optional: A CloudWatch log group

Configuring your Wasabi account

1. Create a Wasabi S3 bucket, or plan to use an already-existing bucket for this transfer. The Wasabi S3 bucket may be in any region, however we recommend keeping the Wasabi S3 destination bucket, AWS S3 source bucket, and EC2 instance all within a close geographical distance to minimize latency.

2. Create an IAM user

3. Create an IAM permissions policy so that AWS may transfer data to your Wasabi S3 bucket using S3 authentication. An example policy for a DataSync transfer is shown below. Please be sure to modify the bucket name to reflect the name of your Wasabi S3 bucket:

"Version": "2012-10-17",
"Statement": [
"Action": [
"Effect": "Allow",
"Resource": "arn:aws:s3:::bucketname"
"Action": [
"Effect": "Allow",
"Resource": "arn:aws:s3:::bucketname/*"

4. Assign the policy to your user by going to Users > username > Policies > Search for the policy you just created, and select the policy (which will assign the policy to the user)

5. Create an access/secret key pair for the user to use with AWS DataSync

Configuring your AWS account

1. Deploy an EC2 instance

Use a DataSync Amazon Machine Image (AMI) in the region of your choice. For the purposes of this KB, we will be utilizing an AWS S3 bucket and EC2 instance in the us-east-1 region. In order to find the latest AMI for your DataSync agent, run the following AWS CLI command (with your preferred region):

aws ssm get-parameter --name /aws/service/datasync/ami --region region

You should see an output similar to below:

$ aws ssm get-parameter --name /aws/service/datasync/ami --region us-east-1
"Parameter": {
"Name": "/aws/service/datasync/ami",
"Type": "String",
"Value": "ami-0885afb7f09f0b602",
"Version": 84,
"LastModifiedDate": "2023-08-15T08:26:13.979000-07:00",
"ARN": "arn:aws:ssm:us-east-1::parameter/aws/service/datasync/ami",
"DataType": "text"

From this, we can see that the latest AMI (as of this article) for DataSync in the us-east-1 region is 'ami-0885afb7f09f0b602'. Copy your AMI value to your clipboard.

In the AWS Console, go to Services > EC2 > Launch Instance:

Name: Optional

AMI: Search for the AMI you just copied. Once you search, go to the Community tab and select the official AWS AMI that you searched for


Instance Type: You may choose any instance type. For larger data sets, we recommend utilizing an instance type with a healthy amount of RAM, vCPUs, and network bandwidth. For the purposes of this guide I will be selecting the c4.2xlarge type

Key pair: Either select an existing EC2 keypair, or choose to create a new one

Network settings: For activation purposes, it is required to check the box to enable "Allow HTTP traffic from the internet" so that the DataSync agent may activate via HTTP port 80 (Note: While the agent will activate via HTTP, all data transfer will occur via HTTPS). You may also disable SSH access to the instance as it is self-contained and does not need to be connected to by the user


No more settings need to be adjusted for the DataSync agent EC2 instance. Click "Launch instance" to continue.

Once the EC2 instance is launched, make note of the public IP address of the instance and copy it to your clipboard for Step 2.

2. Deploy your DataSync Agent 

Go to DataSync > Agents > Create agent

Deploy agent: Amazon EC2

Service endpoint: Public service endpoints in <region>

Activation key: Automatically get the activation key from your agent

Paste the public IP of your EC2 instance into the "Agent address" field and click "Get key"

You should see that the activation was successful with details of your key and agent address


Optionally give your agent a name, then click "Create agent"

You should now be brought to a page showing your Agent ID and showing a status of "online"


3. Create a DataSync Task to copy the data

Go to DataSync > Tasks > Create task

Configure source location

Source location options: Create a new location

Location type: Amazon S3

Region: <bucket region>

S3 bucket: <customer AWS S3 bucket>

Folder: Optional to add a specific prefix you wish to transfer (leave blank for entire bucket)

IAM role: You can choose to either use a preexisting role from your AWS account, or have the console autogenerate a new role for you for this specific task (recommended). If you choose to autogenerate a role, it will automatically have the correct permissions and trust policy assigned to the role in order to allow the DataSync service to assume the role and access the selected source AWS S3 bucket.


Click "Next"

Configure destination location

Create a new location

Location type: Object storage

Agents: Select your agent which we previously created and activated

Server: The endpoint URL for your Wasabi S3 bucket region

Bucket name: The name of your Wasabi S3 bucket you wish to transfer the data to

Folder: (Optional)

Authentication: Enter in the access key and secret key for your Wasabi user that we generated in Step 5 under "Configuring your Wasabi account" of this KB. This keypair set will be used to authenticate the Wasabi-side requests of this operation.



Click "Next"

Configure settings

Task name: Give the task a name

Verify data: Choose whether you want to verify all data, only data transferred, or all data in destination

Set bandwidth limit: Use available

Data transfer configuration: Choose whether to scan all source data or only specific source locations

Transfer mode: Choose whether to transfer only data that has changed (or does not exist in the destination), or all data. If your Wasabi destination bucket does not have any data in it, or contains no data from the S3 bucket, you can select "transfer only data that has changed"

Select whether or not to keep/overwrite files

Additional settings: Click the dropdown for additional setting and uncheck "Copy object tags" as leaving this enabled will cause the verification process to produce an error as Wasabi does currently (as of this article) support object tagging

Schedule: Choose whether to schedule this as an on-going task or not (on demand)

Tags: Do not enable tagging, as Wasabi currently (as of this article) does not support the object tagging feature

Logging: If you wish to capture logs of the DataSync service, you may choose to autogenerate a new logging group for CloudWatch



Click "Next"

Review all settings configured. If the task looks as you are expecting, click "Create task"

At this point, the task has been created and is ready to be run. If you experienced an error while creating the task, please review the error as described by the AWS console and fix accordingly. Once the task has been created successfully, you will be able to view all of the details of the task, along with the ability to run the task.


4. Run the task

Click Start > Start with defaults

Once started, the task status will change to "Running...". You can go to DataSync > Task history to view the current status of your DataSync task's execution. The execution status will first start off as "Launching..." before moving to a "Transferring..." state.

Once the execution has completed and the task has finished transferring files to your Wasabi S3 bucket, you should see that the execution has a status of "Success" with a green checkmark.

At this point, you may check your Wasabi bucket and verify that all of your data was successfully transferred from your AWS S3 bucket.


If your execution status has an execution status of "Error", please review the error message/logs and adjust your task accordingly.

Final Steps

Now that you have successfully transferred data from your AWS S3 bucket to your Wasabi S3 bucket using AWS DataSync, please ensure that you stop/terminate your DataSync Agent EC2 instance so that you no longer incur any charges for this service.
