Is Microsoft 365 backed up?
Most businesses assume Microsoft 365 has their data covered. It doesn't, in the way they think — and the gap catches people out at the worst possible moment.
Short answer: not in the way most people assume. Microsoft keeps the 365 service itself running and resilient — your email and files won't vanish because a Microsoft data centre had a bad day. But recovering your data after you delete something, get hit by ransomware, or have an account compromised is your responsibility, not Microsoft's. That distinction is where businesses get caught out.
What Microsoft actually does
Microsoft protects the platform's availability — keeping the service online and your data replicated across their infrastructure so it isn't lost to a hardware failure. They also keep deleted items for a limited window. What they don't provide is a true backup you control: long-term, point-in-time copies you can restore from after a mistake, an attack, or a malicious deletion.
The shared responsibility model
Microsoft operates on a 'shared responsibility' basis: they secure and run the platform; you're responsible for your data within it. It's in their own terms. Recovering from accidental deletion, a departed employee wiping files, or ransomware encrypting your SharePoint is on you — which is exactly why a proper third-party backup of your 365 data exists.
What a proper 365 backup gives you
A dedicated backup keeps independent, recoverable copies of your email, OneDrive, SharePoint and Teams data — far beyond Microsoft's short retention window, and outside the 365 environment so they survive an attack on it. If something's deleted, corrupted or encrypted, you can roll back to a known-good copy. It fills the gap most businesses don't realise they have.
FAQs
Common questions
Doesn't Microsoft keep my data safe already?
Microsoft keeps the service running and your data replicated against hardware failure, plus a short window for deleted items. What it doesn't do is provide a true, controllable backup you can restore from after a deletion, attack or compromised account — that's your responsibility, and a third-party backup fills it.
What could I actually lose without a 365 backup?
Anything deleted beyond Microsoft's retention window — by accident, by a departing employee, or by ransomware. Once that window passes, the data's gone unless you have your own backup. For most businesses that's an unacceptable risk, and it's easily and affordably fixed.
How do I back up Microsoft 365?
With a dedicated backup service that takes independent, recoverable copies of your email, OneDrive, SharePoint and Teams data, stored outside the 365 environment. We set it up and, crucially, test that it restores — so it's there when you need it.
