Hard drives fail. Ransomware strikes. Laptops get dropped, stolen, or soaked in coffee. Files get accidentally deleted. These things happen every single day to small businesses across Australia — and the ones that recover quickly all have one thing in common: they had a solid backup in place.

The ones that don’t? Some never fully recover. According to research by the Australian Cyber Security Centre (ACSC), ransomware remains one of the most damaging cyber threats for small and medium businesses. And in many cases, a reliable, tested backup is the only thing standing between a bad day and a business-ending event.

The 3-2-1 Backup Rule

If you only remember one thing from this post, make it this: 3-2-1.

  • 3 copies of your data
  • 2 different storage types (e.g. local drive + cloud)
  • 1 copy offsite or in the cloud

This isn’t just best practice — it’s the baseline. A single backup on the same computer isn’t a backup. A USB drive sitting next to your laptop that also gets stolen isn’t a backup. The 3-2-1 rule ensures that even in a worst-case scenario — fire, flood, theft, ransomware — you can recover.

Cloud Backup vs Local Backup — You Need Both

Local backup (external drive or NAS device) gives you fast recovery. If a file gets deleted, you can restore it in minutes. But if your office burns down or ransomware encrypts everything on your network, your local backup goes with it.

Cloud backup solves that problem. Services like Microsoft OneDrive, Backblaze, or Acronis keep a copy of your data offsite, encrypted, and accessible from anywhere. Recovery might take longer depending on your internet speed and data volume, but your data survives any physical disaster.

The right answer for most Sutherland Shire small businesses is both — automated local backup for speed, cloud backup for resilience.

The Bit Everyone Forgets: Testing Your Backup

Here’s a sobering question: when did you last actually restore something from your backup?

Many businesses discover their backup hasn’t been running properly only after a data loss event. Backup software can fail silently — a permissions error, a full drive, a corrupted file — and you won’t know unless you check. A backup you’ve never tested is a backup you can’t rely on.

We recommend testing a restore at least quarterly. Pick a random file or folder, restore it, and confirm it opens correctly. It takes ten minutes and gives you genuine peace of mind.

What Should You Be Backing Up?

For most small businesses, the critical data includes:

  • Client files, contracts, and correspondence
  • Financial records, invoices, and accounting software data (MYOB, Xero)
  • Emails and calendars (especially if hosted locally rather than in the cloud)
  • Custom software databases and configuration files
  • Photos, design files, and any work product that can’t easily be recreated

If you’re using Microsoft 365, it’s worth noting that while your emails and OneDrive files are stored in the cloud, Microsoft does not guarantee point-in-time recovery for accidental deletions beyond the recycle bin period. A dedicated Microsoft 365 backup solution adds that extra protection.

How Much Does It Cost?

Far less than losing everything. A solid cloud backup service for a small business typically runs between $15–$60 per month depending on data volume and the number of devices. A NAS drive for local backup starts at around $300–$500 all up. Compare that to the cost of recreating months of lost work, the reputational damage of not being able to service clients, or the ransom demand from a ransomware attack (commonly $10,000–$50,000+ for SMBs in Australia).
