What method is Microsoft Azure Backup using to encrypt data?

I'm filling in a security assessment form asking for the encryption method ("Are backups encrypted using AES-256 or higher?") used by the Azure backup agent software.

I can't find this piece of information on the Azure backup datasheet (http://azure.microsoft.com/en-us/services/backup/) or the Azure compliance pages (http://azure.microsoft.com/en-us/support/trust-center/compliance/) or anywhere else.

I can find references to "...military-grade AES 256-bit encryption..." on "Storing Encrypted Data in Windows Azure" (http://azure.microsoft.com/blog/2011/04/22/storing-encrypted-data-in-windows-azure/) that tells stories of customers using Azure, however, this is not a direct confirmation of the used encryption method by the current Azure Backup agent software.

Does anyone know or even better can any refer to documentation?

Please see Azure Backup - FAQ page (Security Section). From this page:

Q1. Is the data sent to Azure encrypted?
A1. Yes. Data is encrypted on the on-premises server/client/SCDPM machine using AES256 and the data is sent over a secure HTTPS link.
