For clarity: soyuz is the name of a launch vehicle as well as a manned spacecraft (the Soyuz-TMA-M). The Soyuz spacecraft can return humans to the Earth and of course has the ability to return cargo as well, but since the space is taken up by people that capacity is extremely limited. The Progress can return a very tiny amount of cargo (about 150kg) to Earth using a specialty capsule that was last used in 1994.
