'''Checkpointing''' is a technique that provides [[fault tolerance]] for [[computing]] systems. It involves saving a [[Snapshot (computer storage)|snapshot]] of an [[application software|application]]'s state, so that it can restart from that point in case of [[failure]]. This is particularly important for long-running applications that are executed in failure-prone computing systems.
