If your business uses Microsoft 365, you’re not alone — it’s become the go-to productivity suite for Australian organisations of all sizes. With cloud-hosted email, SharePoint, OneDrive, and Teams, it’s easy to assume your data is safe and backed up.
But here’s the reality:
While Microsoft hosts your data, you are responsible for protecting it. Relying solely on Microsoft to back up your business-critical information could leave you exposed to accidental deletion, cyber threats, or compliance issues.
In this post, we break down why third-party backup services are essential, even if you’re already using Microsoft 365.
Microsoft 365 Has Built-In Protections — But It’s Not Backup
Microsoft does a great job with availability and redundancy. Their infrastructure ensures your data is:
- Available across devices
- Synced in the cloud
- Replicated across data centres for uptime
However, these features are not the same as a true data backup. Microsoft’s native tools (like recycle bins and version history) offer short-term recovery, not long-term protection or point-in-time restore.
Here’s what Microsoft says themselves:
“With Microsoft 365 backup, the customer is responsible for their data. We operate under a shared responsibility model.”

What Microsoft 365 Doesn’t Protect You From
🗑️ Accidental Deletion
Users delete files or emails — sometimes realising it weeks or months later. After the retention period ends, that data is gone forever.
🧑💼 Malicious Insiders
Disgruntled employees can delete sensitive content intentionally. If it’s purged beyond recovery, there’s no native backupto retrieve it.
💻 Ransomware & Malware
Malware can encrypt cloud-based files, sync across devices, and render Teams or OneDrive data inaccessible. Microsoft doesn’t offer full tenant rollback.
🔁 Sync Errors or App Overwrites
Third-party integrations or faulty sync tools can overwrite SharePoint or OneDrive data — often without notice.
⚖️ Compliance & Legal Requirements
Many industries require long-term retention or legal holds beyond 90 days. Microsoft’s built-in archiving tools don’t always meet these obligations out of the box.
What Third-Party Backup Services Actually Offer
Paying for a managed backup solution gives your business:
✅ Point-in-Time Recovery
Restore data from any specific date or time — perfect for ransomware rollback or human error.
✅ Granular Recovery
Recover specific files, folders, emails, or Teams conversations without affecting other data.
✅ Long-Term Retention
Keep records for years — not just weeks — to meet legal, compliance, or internal audit needs.
✅ Protection Against Data Loss
Your data is backed up in a separate, secured environment, outside Microsoft’s native ecosystem.
✅ Simplified Restore Process
Restoring critical data is quick and intuitive — no jumping through Microsoft admin panels or relying on support delays.
Is It Worth Paying for Backup Services?
Absolutely.
Think of backup like business insurance — it may feel optional… until the day you need it.
Consider the cost of:
- Losing an important client file or financial record
- Hours of downtime caused by corrupted SharePoint data
- Failing an audit because email retention wasn’t long enough
- Paying a ransom to restore access to Teams or OneDrive
In comparison, backup services are affordable, predictable, and reliable.
Final Thoughts
Microsoft 365 is powerful — but it’s not immune to data loss.
Paying for backup services isn’t an extra — it’s essential.
If you’re a business that relies on your email, Teams, SharePoint, or OneDrive to run operations, then having a proper backup solution is the safety net you can’t afford to skip.
