Why Microsoft’s shared responsibility model means you need third-party backup

Microsoft is excellent at protecting its cloud infrastructure. Their built-in tools handle redundancy, uptime, and security against external threats, but there’s one area they can’t cover for you: your people. Under Microsoft’s Shared Responsibility model, the data stored in Microsoft 365 is your responsibility. That includes protecting it from accidental deletions, overwrites, or even malicious insider actions.

The human element in data loss

It’s a harsh truth: over 80% of breaches involve human error. While cyber attacks make headlines, everyday slip-ups are the silent threat. From clicking the wrong button to overwriting critical files, human mistakes are the leading cause of data loss. And Microsoft’s retention policies? They’re designed for short-term fixes, not long-term disasters.

If an employee accidentally deletes an email or misconfigures a folder, it may only be recoverable for a limited time – if at all. Worse, when users leave your organisation, retaining their data often falls through the cracks, leaving businesses scrambling when historical information is needed.

Enter SkyKick backup: Your safety net

SkyKick Backup is designed to fill the gaps Microsoft doesn’t cover. It provides automated daily backups of emails, OneDrive, SharePoint, and Teams, ensuring your data is stored safely and recoverable in just a few clicks.

Think beyond cyber threats

While protecting against hackers is crucial, the bigger risk comes from within. With SkyKick Backup, you can confidently handle accidental errors and ensure your business-critical data is never out of reach. It’s not about pointing fingers—it’s about recognising that mistakes happen and having the right tools to respond.
