Before using AZCopy, what do you need to create?

To use AZCopy effectively, generating a shared access signature (SAS) is crucial because it provides secure, delegated access to Azure Storage resources. Without a SAS, users cannot have the required permissions to perform operations like uploading or downloading files to and from Azure Blob Storage. The SAS essentially acts as a temporary key that allows limited access to storage resources while maintaining security.

In many scenarios, even before using AZCopy, users may already have a blob container set up, but if they do not have a SAS, they would be unable to interact with that container. Thus, ensuring that the appropriate access permissions via a SAS are established is a foundational step before leveraging AZCopy to manage data transfers.
