We review the status of neutron backscattering spectrometers on reactors and spallation sources including the most recent instrument developments. After setting the stage by looking briefly at the history of backscattering instruments, we review the current state-of-the-art in backscattering spectrometers leading to the most recent projects. In particular, we discuss the developments at reactors which have led to the classic type of backscattering spectrometers. These instruments typically use cold neutrons along with crystalline monochromators and large crystalline analyzers both of which diffract neutrons very nearly in exact backscattering thereby providing energy resolutions
