Is is possible to backup system state with 2012R2 DC and azure backup?

I have just downloaded the current MARS agent onto a 2012R2 server, which is a DC. When I open Windows Server Backup the local backup option gives me the ability to backup system state. However the Azure options doesn't, it just has the drives.

Is there any way I can use azure backup to backup the active directory info e.g. via system state?

Or do I have to do a 2 stage operation, i.e. backup system state locally, and then back that up to azure?

regards
