After his unfortunate destruction by the hands of the Reclaimer SPARTAN-117, 343 Guilty Spark's backup data and memory, stored in one of the Ark's computers in case such an event were to occur, were activated . The Ark and its Sentinels were notified his destruction and immediately began performing the proper actions of reconstruction (similar to what happened after the destruction of Installation 04). His fate is unknown, presently. However, this is certain: machines can be rebuilt, humans cannot.
