Hmmm... doesn't look like it's the same thing - this instance has
never, to my knowledge, been touched by the windows gui. Another odd
thing we found in testing last night - storage unit group containing 2
of our filers, primarily used to as a stu for ndmp 3 way backups (when
we want them intentionally). Down the drives on the 2 filers, kick off
job that is supposed to go through them, and find it going through a
third filer that is not in the storage unit group. Somehow I don't
think it's managing the NDMP storage units quite right.
