COMPUTER BACKUP POOLS, DISASTER RECOVERY, AND DEFAULT RISK.

Abstract

The authors discuss computer backup pools, where a few members share the ownership, or right for service, of a computer center. Such a center stands by to provide for the lost computing capacity of a member suffering a computer breakdown and disaster recovery. They focus on the reliability of such an arrangement. Two types of default risks are discussed: the probability that the center itself will break down when needed, so that it would be unable to provide service (this is similar to the traditional measure of a 'probability of ruin') and a 'perceived probability of ruin' (the probability that a member will be affected by the failure of the center). It is shown that the membership fee for each participant must be a function of both the payments of all members and their loss (call for service) distributions, reflecting thereby the simultaneity of and mutual interdependence of members.
