Get started with AzCopy
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 files.
AzCopy V10 is the currently supported version of AzCopy.
If you need to use a previous version of AzCopy, see the Use the previous version of AzCopy section of this article.
First, download the AzCopy V10 executable file to any directory on your computer. AzCopy V10 is just an executable file, so there's nothing to install.
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 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 in Windows PowerShell command prompts.
To see a list of commands, type
azcopy -h and then press the ENTER key.
To learn about a specific command, just include the name of the command (For example:
azcopy list -h).
To find detailed reference documentation for each command and command parameter, see azcopy
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.
You can provide authorization credentials by using Azure Active Directory (AD), or by using a Shared Access Signature (SAS) token.
Use this table as a guide:
|Storage type||Currently supported method of authorization|
|Blob storage||Azure AD & SAS|
|Blob storage (hierarchical namespace)||Azure AD & SAS|
|File storage||SAS only|
Option 1: Use Azure Active Directory
This option is available for blob Storage only. By using Azure Active Directory, you can provide credentials once instead of having to append a SAS token to each command.
In the current release, if you plan to copy blobs between storage accounts, you'll have to append a SAS token to each source URL. You can omit the SAS token only from the destination URL. For examples, see Copy blobs between storage accounts.
To authorize access by using Azure AD, see Authorize access to blobs with AzCopy and Azure Active Directory (Azure AD).
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).
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.

Use in a script
Obtain a static download link
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:
--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
The URL appears in the output of this command. Your script can then download AzCopy by using that URL.
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 additional
% character next to existing
% characters in the SAS token string.
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.
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 leverage 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
