And without third-party backup, sensitive business data such as emails or shared files stored in Microsoft 365 are not protected from the most common or most serious data loss issues, such as accidental deletions, malware attacks and more. 

Data protection is an essential aspect of running a business. With the increasing complexity of technology and the ever-growing amount of data, it's becoming more challenging for companies or IT teams to manage it independently.
