In a few days Im going to redo my PDC.  I would like to backup a few of the organizational units of the active directory and not all of it.  Is there a way to only back up parts up the directory and restore them later?

Or do i have to backup everything and then from the restore only do the parts I want?

NTBackup can only backup the whole AD.
Why wouldn't you just prune the directory 1st ?

Yeah, with AD you're stuck with a monolithic directory. Its not like Novell Directory Services (aka eDirectory) where you can partition the directory. Also, with AD, you have to make a server a DC or not a DC, and once you make that choice you can't change it without rebuilding the server. With eDirectory, you can move the directory replicas around pretty much at will.

Are there any utilities out there for backing up and restoring the directory?  Other the NT BACKup of Veritas?

Unless your AD is a monolithic one with tens of thousands of objects, you can simply backup the System State Data.

But the database itself is a single file - NTDS.DIT - and on your PDC it will probably be holding a number of master roles (eg PDC emulator, Global Catalog, Schema Master, Infrastructure Master, RID Master etc), so it's always going to be better if you backup the entire database.

As long as you have at least one other domain controller in the same domain, ideally providing at least one of the FSMO roles (I'm thinking the GC) you can ensure that restoring the system state data will be enough.
