Use the Pattern to select the download blob. And a blob URI is not supported as source to download the blob.The following snapshot is my test result.ġ.Use container as the source and container SAS token. We can download a blob from the container source by using account key or container SAS Token. I still think AzCopy needs the missing part of the SAS URI. I've also tried generating the SAS URI programmatically using the SDK so I can specify a Shared Access Policy, but that's not working either. I am able to use the original SAS URI directly via curl, so it's not a question of the signature being inconsistent. Make sure the value of the Authorization header is formed correctly including the signature." This in my experience indicates that the original URI that the SAS signature was generated upon, is not being reconstructed properly. In any case, AzCopy complains that the "Server failed to authenticate the request. This seems consistent with the 403 error I get when I specify the exact blob key here the container is private. The only other candidate I can find is /Pattern, but that seems more for the case of downloading blobs by enumerating through the contents of the container. IMHO, this should be /SourceKey, but specifying my blob key there returns the error: "The supplied storage key (SourceKey) is not a valid Base64 string." This is consistent with the command line help that describes the parameter as the "Storage account key". If /Source is supposed to be the blob container, and the /SourceSAS is supposed to be the SAS token, then somewhere I need to pass in the actual Blob key (). I'm trying to use AzCopy 5.1.0 to download a single blob from a Blob Storage container using a SAS generated by Storage Explorer:
