Will Superduper copy a TM backup that's located on a Drobo?

I understand, and no, I do not use it that way. It's a way to recover accidentally deleted files, as well as to look back for an older version of a file if needed. I always keep at least two full Superduper clones of all my current drives. One nearby for quick access, an another in a firesafe. I'm doing this because I did did not originally constrain my Time Machine backup to a fixed partition and it needs to be restricted to a maximum size.

Thanks for your response.
