Abstract
This paper derives three evaluation measures of file recovery with n archive copies: when a failure is detected uniformly during (0, T),the mean recovery overhead, the overhead rate and the availability are obtained. Optimal archive copies intervals T* which minimize or maximize those measures are analytically discussed. When faults occur at random, they are given by unique solutions of the same type equations. Finally, a numerical example is shown.
