Optimal policies for a database system with two backup schemes
This paper considers two backup schemes for a database system: a database is updated at a nonhomogeneous Poisson process and an amount of updated files accumulates additively. To ensure the safety of data, full backups are performed at time or when the total updated files have exceeded a threshold level , and between them, cumulative backups as one of incremental backups are made at periodic times ). Using the theory of cumulative processes, the expected cost is obtained, and...
