Microsoft 365 is not backed up the way most people assume. Retention policies and the recycle bin are not a backup — they are a short grace period, and they will not save you from a mistake you notice three months later.

What Microsoft actually covers

Microsoft’s own shared responsibility model is clear: they keep the service running, you are responsible for your data. That gap is where most businesses get caught out.

What we do about it

We back up Exchange, SharePoint, OneDrive and Teams to UK-based storage, then test the restore — because a backup nobody has ever restored from is a hope, not a plan.
