We study an integrable case of n-particle Toda lattice: open chain with boundary terms containing 4 parameters. For this model we construct a Backlund transformation and prove its basic properties: canonicity, commutativity and spectrality. The Backlund transformation can be also viewed as a discretized time dynamics. Two Lax matrices are used: of order 2 and of order 2n + 2, which are mutually dual, sharing the same spectral curve.
