Hmm when I looked at [0] under "Main OSM mirror database" I saw the 
point "mirror production osm main database". The (unanswered) questions 
below (e.g. "what will be mirrored?") are from me, btw.

Some days ago I saw [1] and they state "WM OSM DB ~600GB" but the slide 
also tells that this information comes from a planet-file so - no history..

Okay that bye, bye 2nd plan.
