incidents.<\/li>\n<\/ul>\n<p><\/p>\n<p>That\u2019s exactly why having a <strong>Disaster Recovery Plan (DRP)<\/strong> is essential.

But beware \u2014 a disaster doesn\u2019t have to be massive.

when it comes to human error or cybersecurity.<\/p>\n<p><\/p>\n<p>When talking about a DRP, there are several key terms we need to understand:<\/p>\n<p><\/p>\n<ul>\n<li><strong>Recovery Point

recover it.<\/li>\n<li><strong>Working Recovery Time (WRT)<\/strong>: the time needed to verify that the recovered system works properly.<\/li>\n<li><strong>Maximum Tolerable Downtime (MTD):<\/strong>
