More nuances of why MultiPoint server is different than TS or remote desktop.
MultiPoint 2011 is backed up by SBS 2011 Essentials
As if it’s a client computer, the MultiPoint 2011 Server is backed up as if it’s a client computer. In fact, it’s the *only* server operating system that can be backed up by the SBS 2011 Essentials backup engine.
Unlike the other server skus that well…can be backed up but it’s not supported by Small Business Server Essentials to do so, Multipoint is supported to be backed up by SBS 2011 Essentials.
