Windows Phone

Hi,

Just wondering how whs2011 manages windows phone (7 or 8).
I see that it' possible to install an connector-like application on the phone, but my first concern is backup! and it's not supported.

So what is the best way to auto-backup my windows phone?
Maybe a workflow: phone -> skydrive -> whs2011?
Or server 2012 has such features?

Thanks
