Quickstart: Use the Copy Data tool to copy data
In this quickstart, you use the Azure portal to create a data factory. Then, you use the Copy Data tool to create a pipeline that copies data from a folder in Azure Blob storage to another folder.
If you are new to Azure Data Factory, see Introduction to Azure Data Factory before doing this quickstart.
If you don't have an Azure subscription, create a free account before you begin.
To create Data Factory instances, the user account that you use to sign in to Azure must be a member of the contributor or owner role, or an administrator of the Azure subscription. To view the permissions that you have in the subscription, go to the Azure portal, select your username in the upper-right corner, select More options (...), and then select My permissions. If you have access to multiple subscriptions, select the appropriate subscription.
To create and manage child resources for Data Factory - including datasets, linked services, pipelines, triggers, and integration runtimes - the following requirements are applicable:
- To create and manage child resources in the Azure portal, you must belong to the Data Factory Contributor role at the resource group level or above.
- To create and manage child resources with PowerShell or the SDK, the contributor role at the resource level or above is sufficient.
For sample instructions about how to add a user to a role, see the Add roles article.

Azure storage account
You use a general-purpose Azure storage account (specifically Blob storage) as both source and destination data stores in this quickstart. If you don't have a general-purpose Azure storage account, see Create a storage account to create one.
Get the storage account name and account key
You will need the name and key of your Azure storage account for this quickstart. The following procedure provides steps to get the name and key of your storage account:
In a web browser, go to the Azure portal and sign in using your Azure username and password.
Select All services > Storage > Storage accounts.
In the Storage accounts page, filter for your storage account (if needed), and then select your storage account.
From the <Account name> - Storage account page's sidebar, go to the Settings label and select Access keys. The <Account name> - Access keys appears.
Copy the values for the Storage account name and key1 boxes to the clipboard. Paste them into Notepad or any other editor and save it. You use them later in this quickstart.
Create a blob container
In this section, you create a blob container named adftutorial in Azure Blob storage.
From the <Account name> - Access keys page's sidebar, select Overview > Blobs.
On the <Account name> - Blobs page's toolbar, select Container.
In the New container dialog box, enter adftutorial for the name, and then select OK. The <Account name> - Blobs page is updated to include adftutorial in the list of containers.
Add an input folder and file for the blob container
In this section, you create a folder named input in the container you just created, and then upload a sample file to the input folder. Before you begin, open a text editor such as Notepad, and create a file named emp.txt with the following content:
John, Doe Jane, Doe
Save the file in the C:\ADFv2QuickStartPSH folder. (If the folder doesn't already exist, create it.) Then return to the Azure portal and follow these steps:
In the <Account name> - Blobs page where you left off, select adftutorial from the updated list of containers. (If you closed the window or went to another page, sign in to the Azure portal again, select All services > Storage > Storage accounts, select your storage account, and then select Blobs > adftutorial.)
On the adftutorial container page's toolbar, select Upload.
In the Upload blob page, select the Files box, and then browse to and select the emp.txt file.
Expand the Advanced heading. The page now displays as shown:
In the Upload to folder box, enter input.
Select the Upload button. You should see the emp.txt file and the status of the upload in the list.
Select the Close icon (an X) to close the Upload blob page.
Keep the adftutorial container page open. You use it to verify the output at the end of this quickstart.
Create a data factory
Select New on the left menu, select Data + Analytics, and then select Data Factory.
On the New data factory page, enter ADFTutorialDataFactory for Name.
The name of the Azure data factory must be globally unique. If you see the following error, change the name of the data factory (for example, <yourname>ADFTutorialDataFactory) and try creating again. For naming rules for Data Factory artifacts, see the Data Factory - naming rules article.
For Subscription, select your Azure subscription in which you want to create the data factory.
For Resource Group, use one of the following steps:
- Select Use existing, and select an existing resource group from the list.
- Select Create new, and enter the name of a resource group.
To learn about resource groups, see Using resource groups to manage your Azure resources.
For Version, select V2.
For Location, select the location for the data factory.
The list shows only locations that Data Factory supports, and where your Azure Data Factory meta data will be stored. Please note that the associated data stores (like Azure Storage and Azure SQL Database) and computes (like Azure HDInsight) that Data Factory uses can run in other regions.
After the creation is complete, you see the Data Factory page. Select the Author & Monitor tile to start the Azure Data Factory user interface (UI) application on a separate tab.
Start the Copy Data tool
On the Let's get started page, select the Copy Data tile to start the Copy Data tool.
On the Properties page of the Copy Data tool, you can specify a name for the pipeline and its description, then select Next.
On the Source data store page, complete the following steps:
a. Click + Create new connection to add a connection.
b. Select Azure Blob Storage from the gallery, and then select Next.
c. On the Specify the Azure Blob storage account page, select your storage account from the Storage account name list, and then select Finish.
d. Select the newly created linked service as source, then click Next.
On the Choose the input file or folder page, complete the following steps:
a. Click Browse to navigate to the adftutorial/input folder, select the emp.txt file, then click Choose.
d. Check the Binary copy option to copy file as-is, then select Next.
On the Destination data store page, select the Azure Blob Storage linked service you just created, and then select Next.
On the Choose the output file or folder page, enter adftutorial/output for the folder path, then select Next.
On the Settings page, select Next to use the default configurations.
On the Summary page, review all settings, and select Next.
On the Deployment complete page, select Monitor to monitor the pipeline that you created.
The application switches to the Monitor tab. You see the status of the pipeline on this tab. Select Refresh to refresh the list.
Select the View Activity Runs link in the Actions column. The pipeline has only one activity of type Copy.
To view details about the copy operation, select the Details (eyeglasses image) link in the Actions column. For details about the properties, see Copy Activity overview.
Verify that the emp.txt file is created in the output folder of the adftutorial container. If the output folder does not exist, the Data Factory service automatically creates it.
Switch to the Author tab above the Monitor tab on the left panel so that you can edit linked services, datasets, and pipelines. To learn about editing them in the Data Factory UI, see Create a data factory by using the Azure portal.
The pipeline in this sample copies data from one location to another location in Azure Blob storage. To learn about using Data Factory in more scenarios, go through the tutorials.
