Configuration value persistence management (CVPM) tools and techniques provide faster persistence of networking device configuration values than classic approaches. CVPM consolidates configuration dump events based on certain dump conditions. Configuration value changes are journaled, and running configuration values are dumped to a data store only when the dump conditions are satisfied, instead of dumping all of the running configuration values whenever any of them is changed. Both the persistence of configurations and the restoration of persisted configurations are described. Configuration dump conditions may utilize device availability indicators, device load calculations, configuration change load calculations, dump age, or journal size, for example, or combinations thereof, with various thresholds. Thresholds may be hard, soft, or probabilistic. A wide variety of kinds of configuration values for many different kinds of networking devices may be efficiently and safely persisted and restored using CVPM in various computing environments.
