There is mounting experimental evidence that strong off-equilibrium phenomena, such as `memory' or `ageing' effects, play a crucial role in the physics of vortices in type II superconductors. In the framework of a recently introduced schematic vortex model, we describe the out-of-equilibrium properties of vortex matter. We develop a unified description of `memory' phenomena in magnetic and transport properties, such as magnetization loops and their `anomalous' second peak , logarithmic creep , `anomalous' finite creep rate for T →0, `memory' and `irreversibility' of I - V characteristics, time-dependent critical currents, `rejuvenation' and `ageing' of the system response.
