I am trying to let Latex shorten the authorlist in my bibliography automatically, but it seems to ignore my settings. This is my MWE:
\documentclass{scrreprt}
\usepackage[backend=bibtex, maxnames=2,style=numeric-comp]{biblatex}
\addbibresource{Literatur.bib}
\begin{document}
This is testing text...
\cite{Huebler2011}
\cite{Pierre2015}
\printbibliography
\end{document}
This gives me following result:
As you can see, the selected style is applied, but all authors appear in the bibliography list. I am using TeXnicCenter with MikTex 2.9.
I get one warning message after compilation, which reads Package Biblatex Warning: Using fall-back BibTeX(8) backend. I did some online search on that too, as it seems related to the problem, but haven't found anything helpful. Not specifieing a backend does not generate a bibliography at all.
I hope this doesn't turn out to be a stupid newbie mistake, but could very well be. Any help is greatly appreciated.

.bibfile. You need to separate names with anandin the author list and not with a semicolon, see http://tex.stackexchange.com/q/557/35864 – moewe Jan 25 '17 at 14:14
