volume shadow copy vs data protection manager

Question

trying to implement a VSS backup solution similar to what is described here: http://stackoverflow.com/questions/692848/volume-shadow-copy-vss

there is a new offering called data protection manager: http://www.microsoft.com/systemcenter/dataprotectionmanager/en/us/overview.aspx

how different is this from VSS based solution?

does it solve the problem of implementing a VSS writer?

thanks, JMS
