The very essence of IT Disaster Recovery lies in its ability to mitigate the impact on business operations in the face of adverse IT events. These events can range widely in their cause, consequence, and duration. Here are some examples:
Natural Disasters
Events like earthquakes, floods, and bushfires can wreak havoc on IT infrastructure. The 2019-2020 Australian bushfires, commonly known as “Black Summer,” are a potent reminder.
These catastrophic fires had dire ecological and human consequences and impacted businesses, damaging infrastructure and causing prolonged power outages.
Cyberattacks
Digital threats are omnipresent in today’s interconnected world. Cyberattacks can be particularly damaging regarding data loss and the reputational harm they can inflict on businesses.
For instance, in 2019, the Australian National University (ANU) fell victim to a sophisticated cyberattack where the personal data of over 200,000 students and staff were exposed.
The attackers accessed data extending back 19 years, which included names, addresses, dates of birth, phone numbers, personal email addresses, and emergency contact details, among other information.
Hardware Failures
These can be due to manufacturing defects, wear and tear, or external factors like power outages. For instance, a failure in air conditioning units in a server room can lead to overheating and, subsequently, to server shutdowns.
Software Bugs or Malfunctions
Incorrectly configured software or those with bugs can lead to data corruption or system failures. For instance, an update incompatible with current systems can lead to widespread outages.
Human Errors
Accidental deletions, incorrect configurations, or even unintentional data overwrites can have disastrous effects. A simple act like an employee accidentally deleting critical databases or clicking on a phishing link can set a cascade of IT disruptions into motion.
In essence, IT Disaster Recovery is not just about technology but also about people, processes, and policies.
It’s about ensuring the business can continue functioning, despite these diverse and sometimes unpredictable challenges, by minimising downtime and preventing data loss.
