What is Redundancy?
Redundancy is the deliberate duplication of critical components — power supplies, internet links, servers, data copies — so a single failure never becomes an outage. It is the foundation under failover and high availability.
Why Redundancy matters for Australian businesses
Data is one of your most valuable business assets, and losing it — whether through ransomware, hardware failure, or natural disaster — can be catastrophic. Understanding backup and disaster recovery concepts ensures you can make informed decisions about protecting your business and recovering quickly when things go wrong.
For small and medium businesses in particular, redundancy can make a real difference in maintaining a secure, efficient, and resilient IT environment. Whether you are reviewing your current setup or planning improvements, understanding the role of redundancy in your broader IT strategy will help you have more informed conversations with your IT provider and make better decisions for your business.

Frequently Asked Questions
What is redundancy in IT?
Duplicating critical components — links, power, hardware, data — so the failure of any single element does not interrupt service.
What is a single point of failure?
Any component whose failure alone takes down a service — one internet line, one server, one key person. Identifying them is step one of resilience.
Where should SMBs add redundancy first?
Usually internet connectivity, then power for core equipment, then the server or service whose downtime costs most per hour.
