What constitutes a downtime event? Anything that interrupts your users’ ability to log in and work on their computers, laptops, or smartphones. It can be caused by storm, flood, fire, physical break-in, or cyberhacker intrusion, and result in server failure or data loss.
Since these sorts of interruptions cannot be predicted, you need to be vigilant at all times. You need to have a reliable, automated data backup scheme running 24/7 and a detailed recovery plan in place to help you get back online as quickly as possible after a disaster.
