What is the proper way of backing up the AD system state in Networker 8.2?  I like the granular AD backup using nsradsave but this only back ups the domain partition and not the schema, configuration or GPOs as i understand. 

Do i use DISASTER_RECOVERY:\ or SYSTEM_COMPONENTS or WINDOWS_FEATURES_AND_ROLES saveset?  Is it possible to just backup the registry, NTDS, or whatever AD components are needed without backing up the whole drive?
