Correct the whole download container is holding the full download folder.
We are not using any mounted drives anymore since we have enough space with
the new setup.
It's capped at 2 TB.

Probably best to ask Jürgen Fischer though as I think he was the one to set
it up.  I know he still had some rsync mirroring going on, but I think that
might be to osgeo5 (backup server).

Thanks,
