I thing this is partly the result of people simply parroting shallow statements concerning 'backup, availability, disaster recovery,...' they've read or heard elsewhere, partly the result of a general push towards a service economy where it is considered smart to outsource to 'the experts'. While this may make sense in some cases - e.g. those where the task at hand is not recurring and requires knowledge or equipment which is not at hand and hard/expensive to come by - it is often more expensive and less flexible than just doing the thing yourself. Of course HN is a site frequented by people who are wont to start those same service companies so it is not surprising for there to be a tendency to play up the 'risks' of doing things yourself instead of 'leaving it to the experts'.
