To assure you that I haven&#8217;t taken an odd turn, this is a continuation of a previous post \u2013 <a title=\"How complex is your backup environment?\" href=\"https:\/\/nsrd.info\/blog\/2009\/12\/07\/how-complex-is-your-backup-environment\/\" target=\"_blank\">How Complex is your Backup Environment?<\/a><\/p>\n<p>The question of horses and unicorns covers the introduction of artificial design requirements or operational procedures that see something that should be as simple as a horse turned into something as unique, fragile and irreplaceable as a unicorn.<\/p>\n<p>You see, there&#8217;s lots of horse handlers out there. Even people who aren&#8217;t necessarily trained to look after horses have a good idea of what to do for them. I once had a horse as a kid, and she was relatively easy to look after, particularly since I had a big field to let her roam about in. She practically looked after herself. So if someone turned up tomorrow and asked me to look after their horse for a week, I&#8217;d have a fairly good idea of how to look after it, even if I&#8217;d never dealt with that sort of horse before.<\/p>\n<p>Give me a unicorn and I&#8217;d be in another boat. Literature tells us they&#8217;re fragile things. Heck, they&#8217;ll only <em>let<\/em> certain people go anywhere near them, which seriously reduces the scope of the adult population who can care to their needs.<\/p>\n<p>Not only that, it&#8217;s easy to find practical advise about handling horses on the internet &#8230; of unicorns though it&#8217;s a different story: it&#8217;s all theoretical stuff. It&#8217;s all supposition and old wives tales mixed in with a liberal dosage of imagination. That doesn&#8217;t beget practical tips on handling!<\/p>\n<p>If you&#8217;re an IT manager, you have to accept that staff will periodically move on. Some companies employ more contractors than permanent staff with the <em>expectation<\/em> that staff will regularly move on. You want systems to be straight forward so that:<\/p>\n<ul>\n<li>New staff become productive as soon as possible;<\/li>\n<li>New staff don&#8217;t make serious (or catastrophic) mistakes because someone before them broke the <a title=\"Law of least astonishment\" href=\"http:\/\/en.wikipedia.org\/wiki\/Law_of_least_astonishment\" target=\"_blank\">law of least astonishment<\/a>.<\/li>\n<\/ul>\n<p>This doesn&#8217;t just apply to IT management. As an IT worker, you similarly:<\/p>\n<ul>\n<li>Don&#8217;t want to go into a position where you spend your first three months decoding someone else&#8217;s spaghetti system.<\/li>\n<li>Don&#8217;t want to go into a position where you don&#8217;t notice someone has violated the law of least astonishment and make a &#8230; boo boo.<\/li>\n<\/ul>\n<p>So you see, it&#8217;s all about unicorns and horses. If you go into a job saying that you&#8217;ve worked with horses, or at least have passing familiarity with them, then there&#8217;s a good chance that regardless of whether you&#8217;re presented with a Shetland Pony, an Appaloosa or a monster sized Draught Horse, you&#8217;ll be able to muddle through the process. If you&#8217;re presented with a fragile unicorn, your chances of muddling through aren&#8217;t so good.<\/p>\n<p>Do yourself a favour: make sure your backup system is a horse, not a unicorn.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Is your backup system a unicorn, or is it a horse?
