The exact entanglement dynamics of two qubits in two independent structured reservoirs or in a common structured reservoir with non-resonant interactions has been investigated. The results show that both in the two cases, the robust entanglement preservation could be realized when the non-Markovian and the detuning conditions are satisfied simultaneously. Finally, we give a physical interpretation of this phenomenon via quasimode Hamiltonian.
