title: Sql Server Backup to URL (Azure)
body: <p>I'm trying to take advantage of the new backup to url function in SQL Server.  I have created a valid cert and tried a simple backup, but I get the same error every time no matter what I try.<br>
  I have also tried creating a new managed backup.  With the managed backup I see a new storage container but get no new blobs.  When I look through the logs it is getting the same error.</p>
  
  <p>example:</p>
  
  <pre><code>BACKUP DATABASE [mydb] 
  TO  URL = 'https://mybackups.blob.core.windows.net/sqltest-mssqlserver/backup_2014_08_08.bak' 
  WITH  
  CREDENTIAL = N'AzureCreds' , 
  STATS = 1
  GO
  </code></pre>
  
  <p>Message:</p>
  
  <pre><code>Msg 3293, Level 16, State 1, Line 1
  An error occurred while Backup/Restore to URL was initializing. Error message: Internal engine error, invalid parameters caused fatal error.
  
  Msg 3013, Level 16, State 1, Line 1
