Abstract
Cluster recovery time is reduced by an incremental refresh technique that is described herein. The goal of the technique is to salvage the portion of the redundant distributed database lost (e.g., during a fault) by performing an incremental refresh of only the updates occurring to that portion of the database since the time of loss.
