I have a v large dB 250 gb and I have backed up to azure blob using the below...

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

I now need to do it again is there a way I can do an differential backup e.g. only the changes since last backup

Thanks

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 . enter image description here

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.
