A server subject to random breakdowns and repairs offers services to incomingjobs whose lengths are highly variable. A checkpointing policy aiming to protectagainst possibly lengthy recovery periods is in operation. The problem of howto choose a checkpointing interval in order to optimize performance is addressedby analysing a general queueing model which includes breakdowns, repairs, back-upsand recoveries. Exact solutions are obtained under both Markovian andnon-Markovian assumptions. Numerical experiments illustrate the conditionswhere checkpoints are useful and where they are not, and in the former case,quantify the achievable benefits.
