As Larnu said, you can Call the Differential Backups (SQL Server) .

Since you have full backup the database to you Azure Blob Storage with the satatements:

BACKUP DATABASE [TestDB] 
TO URL = 'https://cloudspacestorage.blob.core.windows.net/backups/Testdb.bak'
WITH CREDENTIAL = 'Backupcredential', STATS = 10 GO

And from the SQL Server Backup to URL , the Bcakup to URL support you create the Differential Backups .

So you can do an differential backup to Azure Blob like this:

BACKUP DATABASE [TestDB] 
TO URL = 'https://cloudspacestorage.blob.core.windows.net/backups/Testdb.bak'
WITH DIFFERENAL 

Hope this helps.
