What is Snapshot?
A snapshot captures the exact state of a system or dataset at a moment in time, allowing near-instant rollback after failed updates, corruption or mistakes. Snapshots complement backups but do not replace them — most live on the same storage as the data they protect.
Why Snapshot 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, snapshots 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 snapshots 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 a snapshot?
A point-in-time capture of a system or volume’s state, enabling rapid rollback to that exact moment — typically created in seconds before changes.
How do snapshots differ from backups?
Snapshots usually reside on the same storage as the source — fast but lost if that storage fails. Backups are independent copies designed to survive any failure.
When should snapshots be used?
Before updates, migrations and configuration changes, and as frequent short-term recovery points layered on top of, never instead of, real backups.
