What is Incremental Backup?
An incremental backup captures only the data changed since the last backup, rather than copying everything each time. Modern systems combine periodic full backups with frequent increments — enabling backups every few minutes with minimal storage and bandwidth.
Why Incremental Backup 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, incremental backups 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 incremental backups 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 an incremental backup?
A backup containing only changes since the previous backup, dramatically reducing time, storage and bandwidth compared with repeated full copies.
What is the difference between incremental and differential?
Incrementals capture changes since the last backup of any type; differentials capture everything since the last full — larger but simpler to restore from.
Do incrementals make restores slower?
Modern platforms synthesise full restore points automatically, so recovery is fast despite incremental capture — the old chain-restore penalty is largely history.
