The journey to Office 365 Part 8: Is a third-party backup or archival solution needed?
Conclusion: Being Cloud-based, Microsoft’s Office 365 includes features that would traditionally be considered backup. According to the Microsoft Office Trust Center, Microsoft establishes itself as a data processor with a primary focus on data privacy and management. It is not responsible for compliance or backup, but reliability and availability. As a result, Microsoft may not be able to provide security and protection to data in a way that meets an organisation’s compliance requirements.
