In this paper, we study on the backward problem for parabolic system and pseudo-parabolic system with conformable derivative. Two these problems have many applications in engineering such as image processing, geophysics, biology, etc. There are two main contributions in this paper. The first major result deals with ill-posedness and regularization for terminal value problem for parabolic system. By applying a new truncation method, we construct a regularized solution. We investigate the existence and uniqueness of regularized problem. Under some suitable conditions of the terminal data, we provide the error estimate between the mild and regularized solutions. The second contribution concerns the existence of a global solution of pseudo-parabolic system. Finally, we also obtain the convergence of the mild solution as the order of derivative approaches $ 1^-. $
