Ransomware is no longer a target solely for large corporations. In other words, you are no longer too small for a cyber attack. Australian small and medium businesses (SMBs) are now prime targets for cybercriminals. As digital transformation expands, so do the risks. According to Mimecast’s State of Email Security report, 75% of businesses suffered a ransomware attack last year, with an average of six days of downtime. Anyone in business is within sight of modern cyber warfare.
These attacks are no longer an ‘if’ but a ‘when.’ Yet many still believe it won’t happen to their business. Unfortunately, that myth is an expensive one to try on. Without a secure and resilient backup strategy, recovery from such an attack can be slow, costly or even impossible. Read on to explore how Backup-as-a-Service (BaaS) offers an effective defence against ransomware, giving Australian SMBs a faster, safer path to recovery.

The Rising Threat of Ransomware for Australian SMBs
Ransomware is no longer just an enterprise-level problem. According to the Australian Cyber Security Centre (ACSC), cybercriminals have adapted their tactics to exploit underprepared SMBs, often with devastating impact. These businesses typically have fewer defences, limited in-house IT staff, and outdated infrastructure, making them low-hanging fruit for attackers.
Moreover, SMBs now handle vast amounts of sensitive data, including financial records, client communications, and Microsoft 365 environments, all of which are valuable to cybercriminals. The result is not just a locked file system but complete operational paralysis, legal implications, and reputational damage. The assumption that smaller businesses are immune to cyber attacks is now dangerously outdated.
Ransomware Reality Check: The Impact on Your Business
When ransomware strikes, the results are swift and severe. Systems are encrypted, access is blocked, and operations halt. For many businesses, the downtime lasts days or weeks, severely affecting productivity and revenue. According to Mimecast’s report, the average downtime after an attack is six days.
But it’s not just about operational disruption. Many ransomware groups now exfiltrate data before encryption, using extortion to double their leverage. That means even if you recover files from a backup, you still face the risk of your data being leaked unless a ransom is paid. Without a verified and secure backup strategy, many SMBs have no other option.
How does Backup-as-a-Service Help Protect Against Ransomware for Australian SMBs?
Backup-as-a-Service protects Australian SMBs from ransomware by storing immutable backups offsite or in the cloud. These backups can’t be changed or encrypted by malware, allowing businesses to quickly restore operations without paying a ransom. Backup-as-a-Service combines frequent, tested backups with strong security controls to support business continuity.
Why You Need a Ransomware-Resilient Backup Strategy
1. Immutability and Isolation
One of the most effective ways to defeat ransomware is to deploy immutable backups, copies of data that malware cannot alter, delete, or encrypt. Cloud-based BaaS platforms ensure that backups are not only regular but also tamper-proof. Features like air-gapping and VLAN-isolated storage protect these backups from even the most advanced ransomware strains.
Organisations create layers of defence by storing backups offline or offsite in the cloud, on tape, or in DR networks. These backups are inaccessible to ransomware actors, making them reliable recovery points in case of an attack.
2. The 3-2-1 Rule in Practice
A best-practice model, the 3-2-1 rule suggests:
- Keeping three copies of your data
- Stored on two different types of media
- With one copy offsite or offline
Amidata takes this a step further by utilising the 3-2-1-1-0 Backup Strategy. It builds upon 3-2-1 by adding one immutable or offline copy and zero errors in backup integrity checks. This ensures that all backups are tested, verified, and recoverable. Learn more about that here.
This approach ensures redundancy and protection even if one backup becomes compromised. By spreading your data across different formats and locations, you reduce the risk of total data loss during a ransomware event or system failure.
Backup-as-a-Service is built around this principle, combining cloud-based immutability with on-premise and off-site options. This flexibility makes it easier for businesses to tailor a backup plan that’s both scalable and ransomware-resilient.
Fast Recovery vs. Paying the Ransom
One of the main reasons businesses pay ransoms is time pressure. ChannelLife reports that most companies that paid did so within 48 hours, often under pressure from customers, employees and financial stakeholders. However, fast recovery is entirely possible with the right Backup-as-a-Service solution.
SMBs can restore data from a verified, unaffected backup in hours, not days. This reduces recovery time objectives (RTO) and recovery point objectives (RPO), ensuring minimal disruption to operations.
Yet, it’s not enough to simply back up. You must test. Alarmingly, 60% of IT professionals are not fully confident in recovering from ransomware. Regular backup verification, test restores, and maintenance of current gold images of key servers are all critical components of a solid Backup-as-a-Service framework.
Security and Monitoring: Built-In Defence
A modern BaaS provider doesn’t just store your data; they actively protect it. These built-in security layers ensure that even if ransomware breaches your primary network, your backups remain clean, isolated, and actionable. This isn’t just smart cyber security; it’s business risk management.
With Backup-as-a-Service, you gain:
- End-to-end encryption for all backup transmissions
- Multi-factor authentication (MFA) for backup access
- Role-based access control, limiting exposure from insider threats
- Anomaly detection, alerting IT teams to suspicious patterns in backup jobs such as sudden spikes in file changes, is often a red flag for ransomware.
Conclusion
Ransomware is no longer a far-off possibility. It is an operational inevitability for many Australian businesses. But you don’t have to face that threat unprepared. Backup-as-a-Service gives you control, continuity and confidence when everything else is at risk.
You’re not just defending data by choosing a tested, monitored, immutable backup strategy. You are preserving your entire business.
