What is Replication?
Replication continuously copies data or entire systems to a secondary location — another server, site or cloud region — keeping the copy current within seconds or minutes. It enables rapid failover for disaster recovery, complementing backups by minimising both downtime and data loss.
Why Replication 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, replication 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 replication 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 replication?
The continuous copying of data or systems to a secondary location, kept nearly current so operations can switch over rapidly after a failure.
How does replication differ from backup?
Replication maintains one up-to-date copy for fast failover; backups preserve many historical points for recovering from deletion, corruption and ransomware. They solve different problems.
Does replication protect against ransomware?
Poorly on its own — encryption replicates to the copy within moments. Pair replication with versioned, immutable backups for ransomware resilience.
