Authentication error with Azure backend from command line


I’ve been using Azure BLOB storage as target for my backup for a couple of years. Now I want to try to access it from the command line, but get auth errors, even though I’m using the same storage URL as exported by the GUI. It’s on the form:


I get the following from the command-line:

ErrorMessage:Server failed to authenticate the request. Make sure the value of Authorization header is formed correctly including the signature.

Any suggestions on what to do?

You’ll need to escape some special characters. If this is a Windows system, try doubling up the % characters in your password.
