Given the really low response rate to the survey (when I usually get more than 2-300 responses for a typical survey), my inference is that the majority of you out there don&#8217;t have well-defined uptime targets (or recovery time objective service level agreements, RTO SLAs, or whatever you want to call it) and so didn&#8217;t respond to the survey. The same thing happens when surveying something like backup testing frequency &#8211; where you *know* you&#8217;re supposed to do it, but don&#8217;t do it enough so feel guilty and don&#8217;t respond to the survey.<\/p>\n<p>For those of you that responded, or didn&#8217;t respond and do have targets, well done! For those of you that don&#8217;t have targets, I don&#8217;t blame you, I blame the environment you&#8217;re in. Most DBAs I know that *want* to do something about HA\/DR are prevented from doing so by their management not placing enough importance on the subject, from talking to a bunch of you. This is also shown by the demand for our various in-person training classes: IE2 on Performance Tuning is usually over-subscribed even though it runs 3-4 times\u00a0per year, but IE3 on HA\/DR has only sold out once even though we generally run it only once per year.<\/p>\n<p>Performance is the number one thing on the collective minds of most I.T. management, not HA\/DR planning, and that&#8217;s just wrong. Business continuity is so crucial, especially in this day and age of close competition where being down can cause fickle customers to move to a different store\/service provider.<\/p>\n<p>If you&#8217;re reading this and you know you don&#8217;t have well-defined uptime targets then I strongly encourage you to raise the issue with your management, as it&#8217;s likely that your entire HA\/DR strategy is lacking too. For more information, you can read the results post from the survey five years ago (<a href=\"https:\/\/www.sqlskills.com\/blogs\/paul\/importance-of-defining-and-measuring-slas\/\" target=\"_blank\">Importance of defining and measuring SLAs<\/a>).<\/p>\n<p>Don&#8217;t wait until disaster strikes to make HA\/DR a priority.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Exactly five years ago I published survey results showing target uptime SLAs and actual uptime measurements.
