Abstract
One embodiment of the present invention provides a switch. The switch includes one or more ports, a persistent storage module, a restoration module, and a retrieval module. The persistent storage module stores configuration information associated with the switch in a data structure, which includes one or more columns for attribute values of the configuration information, in a local persistent storage. The restoration module instantiates a restoration database instance in the persistent storage from an image of the persistent storage. The retrieval module retrieves attribute values from a data structure in a current database instance and the restoration database instance in the persistent storage. The restoration module then applies the differences between attribute values of the restoration database instance and the current database instance in the persistent storage to switch modules of the switch, and operates the restoration database instance as the current database instance in the persistent storage.
