Five words that have saved more than one defense contractor: Native retention is not backup.
Microsoft 365 is remarkably resilient, as a service. Your data within it is a different story. Retention policies, recycle bins, and version history were designed for compliance and convenience, not for recovery. They won't save you from a ransomware event that encrypts synced files, a departed admin's cleanup script, or a well-meaning user who deleted the wrong SharePoint library six weeks ago.
For organizations handling CUI, the stakes are higher: Recovery isn't just an operational concern, it's part of your security story.
What real backup for Microsoft 365 looks like:
• Coverage across the workloads you actually use: Exchange, SharePoint, OneDrive, Teams, Microsoft 365 Groups.
• Backup policies, retention, and encryption you configured on purpose, not defaults you inherited.
• And the step almost everyone skips: TEST RESTORES. A backup you've never restored from is a hypothesis, not a safeguard.
We validate every backup deployment with test restores per workload before handoff, because the worst time to discover a backup gap is the day you need the data back.
When did you last test-restore from your Microsoft 365 backup? If the answer is "never" or "what backup?", let's fix that.
