The Redbook referenced is based on the 4.1.2 client.  With this client you
could not restore inactive copies of the system object.  The 4.2 client does
allow you to restore inactive copies of the system object (WoooHooo!).  You
can also assign a mgmtclass to specify different retentions for the system
objects.  So you could use this instead of doing the NT Backup of the System
State.
