讲座题目：optimizations of incremental backup policies
讲座内容：in order to ensure the data security, plans of incremental backups are usually set up to save the costs which are suffered from full backups. in this presentation, we suppose that failures occur at data updating times and backups are implemented only at the end of data updates, and full backups are done at time t, over time t and update n to balance the costs of data backup and failure recovery. using the theory of renewal process, we obtain the expected costs of backup and recovery and the expected cost rates for full backups. optimum solutions of t and n to minimize the expected cost rates are obtained, and their comparisons are discussed from the optimizations of the integrated models in analytical ways.
