Backup and disaster recovery is the most important IT investment most Melbourne SMEs underspend on. The reason: it doesn’t show up as a problem until it’s already too late, and by then the business has spent years saving the few thousand dollars per year that proper backup costs. We’ve helped enough Melbourne businesses recover from the wrong side of that calculation to know what works in 2026 and what doesn’t.
This post covers the standard you should be hitting, the common shortfalls we see in Melbourne SMEs, what realistic costs look like, and what the post-incident recovery actually feels like — because most owners have only ever read about it.
The 2026 standard: 3-2-1-1-0
The old “3-2-1” backup rule (three copies, two media, one off-site) is no longer enough. Ransomware groups specifically target backups now because that’s what stops them from getting paid. The current standard is the 3-2-1-1-0 backup rule:
- 3 copies of every important piece of data
- 2 different media types — disk and cloud, for instance
- 1 copy off-site — geographically separate from the primary
- 1 immutable copy — written once, can’t be changed or deleted by ransomware that has compromised your environment
- 0 errors — verified by automated tests AND tested restores
The two new requirements (immutability, verified zero errors) are what most Melbourne SMEs miss. They’re also what makes the difference between a 4-hour recovery and a 4-week recovery.
The common shortfalls we see
Melbourne SMEs miss the standard in predictable ways:
“Backups” that share credentials with the main environment. The backup runs as a domain admin. The ransomware compromises a domain admin account. The ransomware encrypts the backups. This is the single most common failure mode we see.
“Off-site” that’s actually just a USB drive on someone’s keyring. Off-site means geographically separate, automated, and verified. Not “I copy it to my home computer once a week”.
Backups that have never been restored. The most-tested process in IT operations is the one that fires once a year and either works or doesn’t. Untested backups have a ~30% failure rate when you actually need them — corruption, missing files, version mismatches, expired credentials. Disaster recovery planning for Australian SMEs covers test cadence properly.
M365 data not backed up at all. “Microsoft has 99.9% uptime” is uptime, not backup. If a user accidentally deletes a SharePoint folder, ransomware encrypts OneDrive content, or a malicious admin wipes mailboxes, M365’s native retention won’t save you long-term. Get a third-party M365 backup tool. Cloud backup solutions covers the options.
RTO and RPO that have never been agreed in writing. Recovery time objective (how long can we be down?) and recovery point objective (how much data can we afford to lose?) drive the entire backup design. Most Melbourne SMEs we onboard have never written these down. RTO vs RPO explained walks through the framework.
What good Melbourne SME backup looks like in 2026
The minimum baseline:
- Per-system inventory. Every server, every line-of-business app, every M365 tenant, every cloud workload, every important file share — listed with RTO, RPO, and current backup status.
- Daily backups for everything that matters, with the cadence increasing for higher-value systems (every 4 hours for the practice management database, daily for OneDrive, weekly for archive folders).
- One immutable copy via cloud object storage with object lock enabled, or via a backup vendor whose architecture provides immutability natively.
- Geographic separation. The off-site copy is in a different city. Sydney, Brisbane, or any non-Melbourne data centre that meets your data sovereignty requirements.
- Automated verification. The backup software checks every backup for completeness; the verification logs are reviewed weekly.
- Test restores. Full restore of a meaningful workload at least every six months. Quarterly is better. The first time you find out the database backup is corrupt should NOT be at hour two of an active incident.
- Documented incident response plan. Names, contact details, decision tree, customer communication templates. Run a tabletop exercise once a year. We’ll do this with you.
What this should cost in Melbourne, 2026
For a 50-staff Melbourne SME with a typical mix of M365, file shares, and one or two on-premises or hosted line-of-business systems:
- Backup tooling (M365): $5-$8 per user per month
- Backup tooling (servers and infrastructure): $80-$200 per server per month, depending on data volume
- Off-site / immutable storage: typically $0.05-$0.15 per GB per month for object-locked storage
- Managed backup operations: $300-$800 per month if you want a service that monitors, verifies and tests on your behalf
- Annual recovery exercise: $1,500-$4,000 per exercise
For most Melbourne SMEs of this size, the total annual spend is $8,000-$25,000. That’s tiny compared to the cost of a four-week recovery from a real incident — which we routinely see priced at $80,000-$300,000 plus the brand damage.
The post-incident reality, in case you’ve never seen one
Hour 0: ransomware fires. Files start encrypting. Endpoint detection alerts.
Hour 1-3: contain the spread. Isolate compromised devices. Identify the attack vector. Assess what’s encrypted vs what’s clean.
Hour 3-12: restore from backup if backups are clean. Negotiate (or not) if backups are also encrypted. Decide on customer communication.
Day 2-5: bring core business systems back online. Validate data integrity. Notify regulators if required (Notifiable Data Breaches scheme, Privacy Act).
Week 2-4: progressive restoration of less critical systems. Insurance claim management. Forensic investigation.
The difference between an SME with proper backup and one without isn’t whether they survive — most do, eventually. It’s whether they’re back to normal operations in 72 hours or 4 weeks.
Business continuity vs disaster recovery
Backup gets your data back. Business continuity planning covers everything else: where do staff work from if the office is unusable, who answers the phones, who calls customers, how do payments still go through. Proper continuity planning extends well beyond IT — but the IT layer is the precondition. No data, no continuity.

What to do next
If you can’t immediately answer “where’s our last backup, when was it last restored, and is it ransomware-safe?” — that’s the conversation to have this fortnight. We’ll do a backup audit and run a real test restore for you in a 5-day fixed-fee engagement.
Book a recovery drill — the first one we run is fixed-fee and you get the report regardless of whether you continue with us.
