I had been running successfully on Server 2012 Essentials with the old backup agent, and recently upgraded to the new agent as required. I have not had a successful backup since.
Most report an "Unsuccessful" backup in the dashboard with an error message saying "Error: The Windows Azure Backup is not available. Wait a few minutes and then try again. If the problem persists, visit the Windows Azure Backup website for more information."
Twice I have gotten instead a report of "Warning", instead.
I have confirmed in the Windows Azure management portal that my vault is properly set up and the server is properly registered. In fact some files have been backed up in the sessions returning a "Warning". Also no connectivity problems at the server end that I am aware of.
Any ideas or help would be greatly appreciated.
Thank you.
