Looking into this more as I get ready to re-install Server 2008 R2. I think I have figured out the steps to create a system state backup for ad by following http://blog.pluralsight.com/backup-and-restore-active-directory-on-windows-server-2008
. This is so I do not lose my users/groups within AD. I also prefer to not have the local machines create new profiles when they login and have missing pieces on desktop/documents etc.
After that, I would re-install Server 2008. At what point during that install would I do the Authoritative Restore of Active Directory to get my users etc back?
Also, regarding robocopy is the correct line for me to use to grab everything on D: partition and copy to e:\ServBack\? robocopy d: e:\ServBack /e /copyall
I am wanting to keep all permissions to the folders when I copy to E, and then again when I copy them back to the D: partition after the OS re-install.
