# Transferring your data

{% hint style="info" %}
This page was generated from content adapted from the [AWS Developer Guide](https://github.com/awsdocs/aws-datasync-user-guide.git)

## Where can I transfer my data?

* **Important**\
  You pay for data transferred between AWS Regions. This transfer is billed as data transfer OUT from the source to destination Region. For more information, see [Data transfer pricing](http://aws.amazon.com/ec2/pricing/on-demand/#Data_Transfer).

## How DataSync handles metadata and special files

* **Note**\
  HDFS uses strings to store file and folder user and group ownership, rather than numeric identifiers (such as UIDs and GIDs). When copying from HDFS to Amazon EFS, FSx for Lustre, FSx for OpenZFS, or FSx for ONTAP (using NFS), default values for UIDs and GIDs are applied on the destination file system. For more information about default values, see [Default POSIX metadata applied by DataSync](#POSIX-metadata).
* **Note**\
  HDFS uses strings to store file and folder user and group ownership, rather than numeric identifiers, such as UIDs and GIDs. DataSync ignores user and group name metadata values stored in Amazon S3 when copying to Amazon EFS or self-managed NFS.
* **Important**\
  If you're transferring objects from a Google Cloud Storage bucket, copying object tags may cause your DataSync task to fail. To prevent this, deselect the **Copy object tags** option when configuring your task settings. For more information, see [File metadata and management options](https://github.com/kevinslin/aws-reference-notes/blob/main/services/aws_data_sync/create-task.md#configure-file).

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://awsnotes.dendron.so/migration-and-transfer/aws-datasync/topics/transferring-your-data.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
