Get started with AzCopy

  • Artikkeli

AzCopy is a command-line utility that you can use to copy blobs or files to or from a storage account. This article helps you download AzCopy, connect to your storage account, and then transfer data.

Note

AzCopy V10 is the currently supported version of AzCopy. The tool is not supported on versions of Windows, Linux, or macOS that are no longer officially maintained.

If you need to use a previous version of AzCopy, see the Use the previous version of AzCopy section of this article.

This video shows you how to download and run the AzCopy utility.

The steps in the video are also described in the following sections.

Use cases for AzCopy

AzCopy can be used to copy your data to, from, or between Azure storage accounts. Common use cases include:

  • Copying data from an on-premises source to an Azure storage account
  • Copying data from an Azure storage account to an on-premises source
  • Copying data from one storage account to another storage account

Each of these use cases has unique options. For example, AzCopy has native commands for copying and/or synchronizing data. This makes AzCopy a flexible tool that can be used for one-time copy activities and ongoing synchronization scenarios. AzCopy also allows you to target specific storage services such as Azure Blob Storage or Azure Files. This allows you to copy data from blob to file, file to blob, file to file, etc.

To learn more about these scenarios, see:

Note

AzCopy does not support scenarios where the source or destination is being actively changed during the transfer.

Install AzCopy on Linux by using a package manager

You can install AzCopy by using a Linux package that is hosted on the Linux Software Repository for Microsoft Products.

  1. Download the repository configuration package.

    Important

    Make sure to replace the distribution and version with the appropriate strings.

    curl -sSL -O https://packages.microsoft.com/config/<distribution>/<version>/packages-microsoft-prod.rpm

  2. Install the repository configuration package.

    sudo rpm -i packages-microsoft-prod.rpm

  3. Delete the repository configuration package after you've installed it.

    rm packages-microsoft-prod.rpm

  4. Update the package index files.

    sudo dnf update

  5. Install AzCopy.

    sudo dnf install azcopy

Download the AzCopy portable binary

As an alternative to installing a package, you can download the AzCopy V10 executable file to any directory on your computer.

These files are compressed as a zip file (Windows and Mac) or a tar file (Linux). To download and decompress the tar file on Linux, see the documentation for your Linux distribution.

For detailed information on AzCopy releases, see the AzCopy release page.

Note

If you want to copy data to and from your Azure Table storage service, then install AzCopy version 7.3.

Run AzCopy

For convenience, consider adding the directory location of the AzCopy executable to your system path for ease of use. That way you can type azcopy from any directory on your system.

If you choose not to add the AzCopy directory to your path, you'll have to change directories to the location of your AzCopy executable and type azcopy or .\azcopy in Windows PowerShell command prompts.

As an owner of your Azure Storage account, you aren't automatically assigned permissions to access data. Before you can do anything meaningful with AzCopy, you need to decide how you'll provide authorization credentials to the storage service.

Authorize AzCopy

You can provide authorization credentials by using Microsoft Entra ID, or by using a Shared Access Signature (SAS) token.

Option 1: Use Microsoft Entra ID

By using Microsoft Entra ID, you can provide credentials once instead of having to append a SAS token to each command.

Option 2: Use a SAS token

You can append a SAS token to each source or destination URL that use in your AzCopy commands.

This example command recursively copies data from a local directory to a blob container. A fictitious SAS token is appended to the end of the container URL.

azcopy copy "C:\local\path" "https://account.blob.core.windows.net/mycontainer1/?sv=2018-03-28&ss=bjqt&srt=sco&sp=rwddgcup&se=2019-05-01T05:01:17Z&st=2019-04-30T21:01:17Z&spr=https&sig=MGCXiyEzbtttkr3ewJIh2AR8KrghSy1DGM9ovN734bQF4%3D" --recursive=true

To learn more about SAS tokens and how to obtain one, see Using shared access signatures (SAS).

Note

The Secure transfer required setting of a storage account determines whether the connection to a storage account is secured with Transport Layer Security (TLS). This setting is enabled by default.

Transfer data

After you've authorized your identity or obtained a SAS token, you can begin transferring data.

To find example commands, see any of these articles.

Note

AzCopy does not have a command to rename files.

Use in a script

Over time, the AzCopy download link will point to new versions of AzCopy. If your script downloads AzCopy, the script might stop working if a newer version of AzCopy modifies features that your script depends upon.

To avoid these issues, obtain a static (unchanging) link to the current version of AzCopy. That way, your script downloads the same exact version of AzCopy each time that it runs.

To obtain the link, run this command:

Operating system Command
Linux curl -s -D- https://aka.ms/downloadazcopy-v10-linux \| grep ^Location
Windows PowerShell (Invoke-WebRequest -Uri https://aka.ms/downloadazcopy-v10-windows -MaximumRedirection 0 -ErrorAction SilentlyContinue).headers.location
PowerShell 6.1+ (Invoke-WebRequest -Uri https://aka.ms/downloadazcopy-v10-windows -MaximumRedirection 0 -ErrorAction SilentlyContinue -SkipHttpErrorCheck).headers.location

Note

For Linux, --strip-components=1 on the tar command removes the top-level folder that contains the version name, and instead extracts the binary directly into the current folder. This allows the script to be updated with a new version of azcopy by only updating the wget URL.

The URL appears in the output of this command. Your script can then download AzCopy by using that URL.

Linux

wget -O azcopy_v10.tar.gz https://aka.ms/downloadazcopy-v10-linux && tar -xf azcopy_v10.tar.gz --strip-components=1

Windows PowerShell

Invoke-WebRequest -Uri 'https://azcopyvnext.azureedge.net/release20220315/azcopy_windows_amd64_10.14.1.zip' -OutFile 'azcopyv10.zip'
Expand-archive -Path '.\azcopyv10.zip' -Destinationpath '.\'
$AzCopy = (Get-ChildItem -path '.\' -Recurse -File -Filter 'azcopy.exe').FullName
# Invoke AzCopy 
& $AzCopy

PowerShell 6.1+

Invoke-WebRequest -Uri 'https://azcopyvnext.azureedge.net/release20220315/azcopy_windows_amd64_10.14.1.zip' -OutFile 'azcopyv10.zip'
$AzCopy = (Expand-archive -Path '.\azcopyv10.zip' -Destinationpath '.\' -PassThru | where-object {$_.Name -eq 'azcopy.exe'}).FullName
# Invoke AzCopy
& $AzCopy

Escape special characters in SAS tokens

In batch files that have the .cmd extension, you'll have to escape the % characters that appear in SAS tokens. You can do that by adding an extra % character next to existing % characters in the SAS token string. The resulting character sequence appears as %%. Make sure to add an extra ^ before each & character to create the character sequence ^&.

Run scripts by using Jenkins

If you plan to use Jenkins to run scripts, make sure to place the following command at the beginning of the script.

/usr/bin/keyctl new_session

Use in Azure Storage Explorer

Storage Explorer uses AzCopy to perform all of its data transfer operations. You can use Storage Explorer if you want to apply the performance advantages of AzCopy, but you prefer to use a graphical user interface rather than the command line to interact with your files.

Storage Explorer uses your account key to perform operations, so after you sign into Storage Explorer, you won't need to provide additional authorization credentials.

Configure, optimize, and fix

Use a previous version (deprecated)
