We compute diffractive structure functions for both protons and nuclei in the framework of color glass condensate models with impact parameter dependence. These models have previously been shown to provide good agreement with inclusive F2 measurements and exclusive vector meson measurements at DESY's Hadron-Electron Ring Accelerator (HERA). For nuclei, they provide good (parameter free) agreement with the inclusive F2 data. We demonstrate good agreement of our computations with HERA measurements on inclusive diffraction. We extend our analysis to nuclei and predict the pattern of enhancement and suppression of the diffractive structure functions that can be measured at an electron-ion collider. We discuss how the impact parameter dependence crucially affects our analysis, in particular for large invariant masses at fixed Q2.
