We propose a set of differential techniques to allow transientlypowered embedded devices reduce the amount of data written on non-volatile memory during checkpoints used to cross times of energy unavailability. These techniques track modifications in the application state to isolate data from the slice of the previous checkpoint that remains unaltered. At the following checkpoint, our approach may thus only update the parts it detects as modified. This allows us to shift part of the energy budget from checkpointing overhead to useful computations, yielding better overall energy efficiency.
