Yeah, we've mirrored it over.
The images for both sites combined is around 60G, the database is a few gig in addition to that. Because of the way it was all formed out of one site, the images were never separated so I have no idea how big each site would be individually. One day I might run a big fat query over the database and separate out all the images into the appropriate collections but I'm really lazy and it doesn't really matter.
I've been looking recently at replacing the core database server with something with higher specs, but it's all money and .. well, the sites don't have any
I'm stoked it's still all running on the hardware it has been for a long time now, those poor little servers have had quite a hard life. And no hardware failures (touch wood), which will be a nightmare because it's really hard for us to physically work on servers on the other side of the planet...
