We investigate solutions of backward stochastic differential equations (BSDE)with time delayed generators driven by Brownian motions and Poisson randommeasures, that constitute the two components of a Levy process. In this newtype of equations, the generator can depend on the past values of a solution,by feeding them back into the dynamics with a time lag. For such time delayedBSDE, we prove existence and uniqueness of solutions provided we restrict on asufficiently small time horizon or the generator possesses a sufficiently smallLipschitz constant. We study differentiability in the variational or Malliavinsense and derive equations that are satisfied by the Malliavin gradientprocesses. On the chosen stochastic basis this addresses smoothness both withrespect to the continuous part of our Levy process in terms of the classicalMalliavin derivative for Hilbert space valued random variables, as well as withrespect to the pure jump component for which it takes the form of an incrementquotient operator related to the Picard difference operator.
