Data is the key to almost all solutions. Obviously, at some point, we will need to move it. And this is when AzCopy will come to the rescue. In this short post/video I will share how you can securely copy a Zip file (aka. data), from one location (blob storage, AWS) to a blob storage in an Azure subscription (the
same subscription or a different one).
What is AzCopy
AzCopy is a command-line utility that you can use to copy blobs or files to or from a storage account. It can run on
Windows, Mac, and Linux. And... It's already available pre-install inside Cloud Shell!
How it works
AzCopy can do many things but let's focus on the "copy" feature. To copy a file from a location to another one here
the command to execute:
azcopy copy https://url-source https://url-destination
It looks simple, right? And it is. To keep it secure AzCopy can use Shared Access Signature (SAS) tokens. To get those
in Azure, you can execute a command (ex: az storage container generate-sas) or use the Azure Portal.
Once you are in the Azure portal open the account storage of your source or destination (you will have to do both).
From the option on the left search for
Shared
access signature or just
sas and click on it. Select the type of options you need. A best practice is to
allow the minimum requirements. If you know you are only moving files then unchecked the File, Queue, and Table. Same
things for the resources types, permissions, and expiry date/time. Once you are done click the
Generate SAS and
connection string button.
Use those URLs with the SAS token in your command, and voila!
