How to transfert data between Azure subscription from Windows, Linux, OS X, or the cloud

(Ce billet en aussi disponible en français: Comment transféré des données entre abonnements Azure depuis Windows, Linux, OS X, ou le cloud)

Copy, Download or Upload from-to any combination of Windows, Linux, OS X, or the cloud

Data is and will always be our primary concern. Whether shaped as text files, images, VM VHDs or any other ways at some point in time our data need to be moved. I already wrote about it previously, and the content of this post is still valuable today, but I wanted to share new options and convert all ground (meaning Linux, Windows and OS X).


Here few scenarios why you would want to move data.
  • Your Microsoft Azure trial is ending.
  • You are creating a new web application, and you have all those images that need to be move.
  • You have a Virtual Machine that you would like to move in the cloud or from the cloud.
  • ...

AZCopy (Windows)

AzCopy is a fantastic command-line tool for copying data to and from Microsoft Azure Blob, File, and Table storage. At the moment, to write this post AzCopy is only available for Windows users. Another solution will be introduced later in this post for Mac and Linux users.
In his simplest expression, an AzCopy command looks like this:
AzCopy /Source:<source> /Dest:<destination> [Options]
If you earlier have installed an Azure SDK on your machine, you already have it. By default, AzCopy is installed to %ProgramFiles(x86)%\Microsoft SDKs\Azure\AzCopy (64-bit Windows) or %ProgramFiles%\Microsoft SDKs\Azure\AzCopy (32-bit Windows).
If you need only AzCopy for a server, you can download the latest version of AzCopy.
Let's see some frequent usage. First let's say you need do move all those images from your server to an Azure blob storage.

AzCopy /Source:C:\MyWebApp\images /Dest:https://frankysnotes.blob.core.windows.net/blog /DestKey:4YvvYDTg3UUpky8Rj5bDG4KO/R1FdtssxVnunsEd/4rAS04V2LkO0F8mXbddAv39WtCo5LW6JyvfhA== /S


Then to copy those images to another subscription very easy.

AzCopy Parameters

These examples were simple, but AzCopy is a very powerful tool. I invite you to type one of the following commands to discover more about using AzCopy:
  • For detailed command-line help for AzCopy: AzCopy /?
  • For command-line examples: AzCopy /?:Samples

Azure CLI (Windows, Linux, OS X)

Azure CLI is a set of cross-platform commands for the Azure Platform. It gives tools to manipulate all Azure components, but this post will focus on azure storage features.
Let's start by installing Azure CLI. Of course, you can download an installer but since everything is evolving very fast with not getting it from Node Package Manager (npm).

sudo npm install azure-cli -g


To keep the previous scenario, let's try to copy all images to a blob storage. Unfortunately, Azure CLI doesn't offer the same flexibility as AzCopy,and you must upload the file one by one. However, to upload all images from a folder, we can easily put the command in a loop.

for f in Documents/images/*.jpg
   azure storage blob upload -a frankysnotes -k YoMjXMDe+694FGgOaN0oaRdOF6s1ktMgkB6pBx2vnAr8AOXm3HTF7tT0NQWvGrWnWj5m4X1U0HIPUIAA==  $f blogimages


In the previous command -a was the account name, and -k was the Access key. This two information can easily be found in the Azure portal. From the portal (https://portal.azure.com), select the storage account. In the right band click-on Access keys.


To copy a file (ex: a VM disk aka VHD) from one storage to another one in a different subscription or region, it's really easy. This time we will use the command azure storage blob copy start and the -a and -k are related to our destination.

azure storage blob copy start 'https://frankysnotes.blob.core.windows.net/blogimages/20151011_151451.MOV' imagesbackup -k EwXpZ2uZ3zrjEbpBGDfsefWkj3GnuFdPCt2QY5fJcb6kMqV2A0+2TsGno+mk9vEXc5Uw1XiouvAiTS7Kr5OGzA== -a frankshare

The nice thing about this command is that it's asynchronous. To see the status of your copy just execute the command azure storage blob copy show

azure storage blob copy show -a frankshare -k YoMjXMDe+694FGgOaN0oPaRdOF6s1ktMgkB6pBx2vnAr8AOXm3HTF7tT0NQVxsqhWvGrWnWj5m4X1U0HIPUIAA== imagesbackup 20151011_151451.MOV



It's just the beginning

This post was just an introduction to two very powerful tools. I strongly suggest to go dig in the official documentation to learn more. Use the comment to share all your questions and suggestion.
