Reliability means continuing to work correctly, even when things go wrong. Common faults and preventions include: Hardware faults: hard disks crash, blackout, incorrect network configuration,… Add redundancy to individual hardware components to reduce the failure rate. As long as we can restore a backup onto a new machine quickly, the downtime is not fatal....
