In Lightroom there is a back-up folder which I had so far overlooked.

I want to reorganize my back-ups, and have all back-ups in the back-up folder. Which so far had been on my main disc.

When I moved it to the external hard drive, it just copied. Now I have two back-up folders, and I erased the copy immediately in order not to drive Lightroom crazy with two back-up folders.

(for copying I want to use SuperDuper in order to get everything right).

How can I move the folder?

Holding command while dragging a folder/file from one drive to another in the Finder will move that file/folder over completely, and won't make a copy.

Just a piece of information: when moving data within a volume -- say Macintosh HD -- then dragging one folder from one location to another usually moves the folder. If you move files and folders between volumes (from your internal to your external harddrive, the Finder will copy the data. This is expected behavior.
