It is not currently possible in a single step, but you can accomplish it this way:
1. Select all elements in diagram you want to copy (Edit/Select all or CTRL+A)
2. Create a new empty diagram of the same type
3. Paste copied elements (CTRL+V)
4. Choose whether you want create unbound independent copy (the first option - Paste as an independent copy) or you want share model of pasted elements with original elements (the second option - Paste as a new instance of the original model element).
5. Confirm your choice using OK button - you have a copy of diagram, now.
I hope I helped you.
P.S. In one of next versions I can add special feature for copying of diagrams.
