There’s a common assumption in IT: “We’re on Microsoft 365 — our data is safe.” It’s an easy conclusion to reach. Microsoft 365 is highly available, rarely goes down, and replicates data across multiple datacentres. But availability and backup are not the same thing.
Microsoft keeps the platform running. Protecting your data is your responsibility.
Microsoft’s own Service Agreement says it clearly: organisations should “regularly back up content and data stored on the services using third-party applications and services.” Under the Shared Responsibility Model, Microsoft owns the infrastructure you own the data on it.
Where Things Go Wrong
Most data loss in Microsoft 365 isn’t caused by Microsoft failing. It’s caused by what happens inside your own tenant:
A script runs against the wrong scope and wipes data across multiple workloads
Ransomware encrypts files that then sync and replicate across OneDrive
A Teams channel or SharePoint site is deleted and isn’t noticed until it’s gone for good
A compromised admin account alters or deletes identity configurations in Entra ID
A retention policy changes, and data ages out with no way to get it back
In every case, the platform is working normally. Recovery responsibility sits with you.
The threat environment makes this more urgent. Ransomware attacks rose 126% in Q1 2025, and 40% now specifically target cloud and hybrid environments. Microsoft blocked 7,000 password attacks per second against Entra ID in 2025 alone.
Our Solution
We now provide ransomware-resistant backup and recovery for Microsoft 365, Microsoft Entra ID and Xero — giving organisations a genuine recovery capability that sits independently of their live environment.
Key features:
Immutable, ransomware-resistant backups — backups that can’t be altered or deleted, even by a compromised account
Fast granular recovery — restore individual emails, files, mailboxes or entire sites to a specific point in time
Entra ID configuration backup — protect and restore identity policies, role assignments and access configurations
Unlimited retention — keep data as long as your business or compliance needs require
Isolated storage — backups held outside your production tenant for a clean, independent recovery path
The Right Question to Ask
Rather than “does Microsoft back us up?”, ask:
“If something went wrong right now, how would we recover — and how confident are we?”
If the answer isn’t clear, it’s worth a conversation.
