Configure backup / slave and integrate to master for sync

There is plenty of documentation that talks about how UCS supports backup UCS roles. However I am unable to find any documentation on HOW to set this up.

Maybe I am missing something, but I have read through the latest documentation here (I do not see any instructions on how to deploy and set up a backup or slave server and integrate into UCS master):

Is there any white papers or documents that detail steps on how to properly set up a backup UCS and sync AD, LDAP, Mail, Radius, DHCP, and DNS?

Also to confirm a backup UCS can be used as a DC registration point correct?
