Abstract
Methods, systems, and computer program products for backup memory administration are provided. Embodiments include storing in an active memory device, by a memory backup controller, blocks of computer data received from random access memory; recording in a change log, by the memory backup controller, identifications of each block of computer data that is stored in the active memory device; detecting, by the memory backup controller, a backup trigger event; and responsive to the detecting of the backup trigger event: copying, by the memory backup controller, from the active memory device, to a backup memory device, the blocks of data identified in the change log; and clearing, by the memory backup controller, the change log.
