We presented spectroscopic and photometric observations of V407 Cygni obtained during 2006-2011. Our data shows the different activity stages connected with the two components of this symbiotic binary system. Cool giant exhibits pulsation character typical for Mira-type stars. Simultaneously, classical nova outburst connected with hot white dwarf was observed in 2010. Multicolour photometry and spectra obtained in a wide wave range are necessary to understand behaviour of such extreme binary. Our long-term observations together with gamma-ray, X-ray and radio monitoring reported by other authors covered the whole spectral domain and provide a lot of useful information about the nature of V407 Cyg.
