install RSYNC (archlinux)

Today I tried this several times while the Pibox was connected by cable. And that was after the stupid mistake to try this while it worked as the PirateBox and then it has of course no internet connection....Although the viewable information in really not very clear about that.
Please advise how to install Rsync on the archlinux PirateBox.
