I was setting up a new build definition today and noticed there is an option 'Copy build output to the following Source Control folder'. I don't believe I have seen this before. It appears to me from searching google that it might be new as of TFS 11 (AKA TFS 2012) which I do not have installed on my system (or any system in my company network to my knowledge). My company uses TFS 2010 right now.
I went to another user who is able to view build definitions and it also was present when the build definitions were viewed.
This is what i see:

My questions:
1) Was this a part of TFS 2010 and I am just not remembering seeing it?
2) If this IS part of TFS 2010, how to enable this option (it is disabled).
3) If this is NOT a part of TFS 2010, how did it get there?

I have this in TFS/VS 2010 (SP1):
