Microsoft 365 backup is an independent copy of a company's email, OneDrive and SharePoint files and Teams chats, stored outside Microsoft. It is needed because, under Microsoft's shared responsibility model, Microsoft keeps the service running but protecting the data is up to the customer: items deleted by mistake, removed by a former employee or encrypted by ransomware cannot be recovered once retention periods expire.
