Use data transfer tools for Azure Stack storage
Applies to: Azure Stack integrated systems and Azure Stack Development Kit
Microsoft Azure Stack provides a set of the storage services for disks, blobs, tables, queues, and account management functions. You can use a set of Azure storage tools if you want to manage or move data to or from Azure Stack storage. This article provides an overview of the available tools.
Your requirements determine which of the following tools works best for you:
A storage-specific, command-line utility that you can download to copy data from one object to another object within your storage account, or between storage accounts.
A task-based, command-line shell and scripting language designed especially for system administration.
An open-source, cross-platform tool that provides a set of commands for working with the Azure and Azure Stack platforms.
An easy-to-use stand-alone app with a user interface.
A virtual file system driver for Azure Blob Storage, which allows you to access your existing block blob data in your Storage account through the Linux file system.
Due to the storage services differences between Azure and Azure Stack, there might be some specific requirements for each tool described in the following sections. For a comparison between Azure Stack storage and Azure storage, see Azure Stack storage: Differences and considerations.
AzCopy is a command-line utility designed to copy data to and from Microsoft Azure blob and table storage using simple commands with optimal performance. You can copy data from one object to another within your storage account, or between storage accounts.
Download and install AzCopy
There are two versions of the AzCopy utility: AzCopy on Windows and AzCopy on Linux.
AzCopy on Windows
- Download the supported version of AzCopy for Azure Stack. You can install and use AzCopy on Azure Stack the same way as Azure. For more information, see AzCopy on Windows.
AzCopy on Linux
- You can install and use AzCopy on Azure Stack the same way as Azure. For more information, see AzCopy on Linux.
- For previous versions (1802 to 1809 updates), see the installation steps for AzCopy 7.1 and earlier versions.
AzCopy command examples for data transfer
Download all blobs to a local disk
AzCopy.exe /source:https://myaccount.blob.local.azurestack.external/mycontainer /dest:C:\myfolder /sourcekey:<key> /S
azcopy \ --source https://myaccount.blob.local.azurestack.external/mycontainer \ --destination /mnt/myfiles \ --source-key <key> \ --recursive
Upload single file to virtual directory
AzCopy /Source:C:\myfolder /Dest:https://myaccount.blob.local.azurestack.external/mycontainer/vd /DestKey:key /Pattern:abc.txt
azcopy \ --source /mnt/myfiles/abc.txt \ --destination https://myaccount.blob.local.azurestack.external/mycontainer/vd/abc.txt \ --dest-key <key>
Move data between Azure and Azure Stack storage
Asynchronous data transfer between Azure storage and Azure Stack is not supported. You need to specify the transfer with the /SyncCopy or --sync-copy option.
Azcopy /Source:https://myaccount.blob.local.azurestack.external/mycontainer /Dest:https://myaccount2.blob.core.windows.net/mycontainer2 /SourceKey:AzSKey /DestKey:Azurekey /S /SyncCopy
azcopy \ --source https://myaccount1.blob.local.azurestack.external/myContainer/ \ --destination https://myaccount2.blob.core.windows.net/myContainer/ \ --source-key <key1> \ --dest-key <key2> \ --include "abc.txt" \ --sync-copy
Azcopy known issues
- Any AzCopy operation on a file store is not available because file storage is not yet available in Azure Stack.
- Asynchronous data transfer between Azure storage and Azure Stack is not supported. You can specify the transfer with the /SyncCopy option to copy the data.
- The Linux version of Azcopy only supports 1802 update or later versions. And it doesn’t support Table service.
Azure PowerShell is a module that provides cmdlets for managing services on both Azure and Azure Stack. It's a task-based, command-line shell and scripting language designed especially for system administration.
Install and Configure PowerShell for Azure Stack
Azure Stack compatible Azure PowerShell modules are required to work with Azure Stack. For more information, see Install PowerShell for Azure Stack and Configure the Azure Stack user's PowerShell environment to learn more.
PowerShell Sample script for Azure Stack
This sample assume you have successfully Installed PowerShell for Azure Stack. This script will help you complete the configuration and ask your Azure Stack tenant credentials to add your account to the local PowerShell environment. Then, the script will set the default Azure subscription, create a new storage account in Azure, create a new container in this new storage account, and upload an existing image file (blob) to that container. After the script lists all blobs in that container, it will create a new destination directory on your local computer and download the image file.
- Install Azure Stack-compatible Azure PowerShell modules.
- Download the tools required to work with Azure Stack.
- Open Windows PowerShell ISE and Run as Administrator, click File > New to create a new script file.
- Copy the script below and paste to the new script file.
- Update the script variables based on your configuration settings.
This script has to be run at the root directory for AzureStack_Tools.

PowerShell known issues
The current compatible Azure PowerShell module version for Azure Stack is 1.2.11 for the user operations. It’s different from the latest version of Azure PowerShell. This difference impacts storage services operation:
The return value format of
Get-AzureRmStorageAccountKey in version 1.2.11 has two properties:
Key2, while the current Azure version returns an array containing all the account keys.
# This command gets a specific key for a storage account, # and works for Azure PowerShell version 1.4, and later versions. (Get-AzureRmStorageAccountKey -ResourceGroupName "RG01" ` -AccountName "MyStorageAccount").Value # This command gets a specific key for a storage account, # and works for Azure PowerShell version 1.3.2, and previous versions. (Get-AzureRmStorageAccountKey -ResourceGroupName "RG01" ` -AccountName "MyStorageAccount").Key1

The Azure CLI is Azure’s command-line experience for managing Azure resources. You can install it on macOS, Linux, and Windows and run it from the command line.
Azure CLI is optimized for managing and administering Azure resources from the command line, and for building automation scripts that work against the Azure Resource Manager. It provides many of the same functions found in the Azure Stack portal, including rich data access.
Azure Stack requires Azure CLI version 2.0 or later. For more information about installing and configuring Azure CLI with Azure Stack, see Install and configure Azure Stack CLI. For more information about how to use the Azure CLI to perform several tasks working with resources in your Azure Stack storage account, see Using the Azure CLI with Azure storage
Azure CLI sample script for Azure Stack
Once you complete the CLI installation and configuration, you can try the following steps to work with a small shell sample script to interact with Azure Stack storage resources. The script completes the following actions:
- Creates a new container in your storage account.
- Uploads an existing file (as a blob) to the container.
- Lists all blobs in the container.
- Downloads the file to a destination on your local computer that you specify.
Before you run this script, make sure that you can successfully connect to, and sign in to the target Azure Stack.
- Open your favorite text editor, then copy and paste the preceding script into the editor.
- Update the script's variables to reflect your configuration settings.
- After you've updated the necessary variables, save the script, and exit your editor. The next steps assume you've named your script my_storage_sample.sh.
- Mark the script as executable, if necessary:
chmod +x my_storage_sample.sh
- Execute the script. For example, in Bash:
#!/bin/bash # A simple Azure Stack storage example script export AZURESTACK_RESOURCE_GROUP=<resource_group_name> export AZURESTACK_RG_LOCATION="local" export AZURESTACK_STORAGE_ACCOUNT_NAME=<storage_account_name> export AZURESTACK_STORAGE_CONTAINER_NAME=<container_name> export AZURESTACK_STORAGE_BLOB_NAME=<blob_name> export FILE_TO_UPLOAD=<file_to_upload> export DESTINATION_FILE=<destination_file> echo "Creating the resource group..." az group create --name $AZURESTACK_RESOURCE_GROUP --location $AZURESTACK_RG_LOCATION echo "Creating the storage account..." az storage account create --name $AZURESTACK_STORAGE_ACCOUNT_NAME --resource-group $AZURESTACK_RESOURCE_GROUP --account-type Standard_LRS echo "Creating the blob container..." az storage container create --name $AZURESTACK_STORAGE_CONTAINER_NAME --account-name $AZURESTACK_STORAGE_ACCOUNT_NAME echo "Uploading the file..." az storage blob upload --container-name $AZURESTACK_STORAGE_CONTAINER_NAME --file $FILE_TO_UPLOAD --name $AZURESTACK_STORAGE_BLOB_NAME --account-name $AZURESTACK_STORAGE_ACCOUNT_NAME echo "Listing the blobs..." az storage blob list --container-name $AZURESTACK_STORAGE_CONTAINER_NAME --account-name $AZURESTACK_STORAGE_ACCOUNT_NAME --output table echo "Downloading the file..." az storage blob download --container-name $AZURESTACK_STORAGE_CONTAINER_NAME --account-name $AZURESTACK_STORAGE_ACCOUNT_NAME --name $AZURESTACK_STORAGE_BLOB_NAME --file $DESTINATION_FILE --output table echo "Done"

Blobfuse is a virtual file system driver for Azure Blob Storage, which allows you to access your existing block blob data in your Storage account through the Linux file system. Azure Blob Storage is an object storage service and therefore does not have a hierarchical namespace. Blobfuse provides this namespace using the virtual directory scheme with the use of forward-slash
/ as a delimiter. Blobfuse works on both Azure and Azure Stack.
To learn more about mounting Blob storage as a file system with Blobfuse on Linux, see How to mount Blob storage as a file system with Blobfuse.
For Azure Stack, blobEndpoint needs to be specified besides accountName, accountKey/sasToken, containerName, while configuring your Storage account credentials in the step of preparing for mounting.
In the Azure Stack development Kit, the blobEndpoint should be
myaccount.blob.local.azurestack.external. In Azure Stack integrated system, contact your cloud administrator if you’re not sure about your endpoint.
Please be aware that accountKey and sasToken can only be configured one at a time. When storage account key is given, the credentials configuration file is in the following format:
accountName myaccount accountKey myaccesskey== containerName mycontainer blobEndpoint myaccount.blob.local.azurestack.external
When shared access token is given, the credentials configuration file is in the following format:
accountName myaccount sasToken ?mysastoken containerName mycontainer blobEndpoint myaccount.blob.local.azurestack.external
