Implementation of a File-level Continuous Data Protection System and its Survivability Quantification
Lina Wang · 2012
Regarding the defects of traditional disaster tolerant technology,a novel file-level continuous data protection system was proposed.The deposition method and the design of CDP components were described first.Next the structure of CDP package,data transportation protocol,the logical/physical structure for data storing,and task scheduling methodology were designed.The process of data recovery and data view producing algorithm were presented based on the design mentioned above.Then the algorithm for restoring any time point file and querying any time point file view was designed.Finally a model based on Semi-Markov Process was established and survivability metric was calculated,some promising improvement method was given.
