Problem Description
After performing a Druva file-level restore of an Azure Virtual Machine (VM), you can't access restored folders using direct blob URLs. The error message you see is: "The specified blob does not exist." While you can see the folder structure in the Azure portal, direct URL-based access to the folders fails. You can, however, access and download individual files within those folders successfully using direct URLs or Shared Access Signature (SAS) tokens.
Cause
This issue is due to the way Azure Blob Storage handles folders. In Azure, folders are virtual constructs, not actual objects with their own addresses. You can't target them directly with a URL. Only file-level access is supported via direct URLs or SAS tokens because files are the specific objects stored in the blob. This is standard behavior for Azure Blob Storage and not a limitation of Druva's restore process.
Resolution
This behavior is expected in Azure Blob Storage. To access your restored data, you have a couple of options:
Browse and Download: Use the Azure portal to navigate to the desired files and download them.
File-level URLs: Generate a Shared Access Signature (SAS) token for individual files to access them directly.
