For a long time, I believed that Microsoft 365 (M365) stored data redundantly across multiple active-active data centers and regions. While it seemed like a logical expectation, I recently needed legal documentation to verify this assumption.
After some research, I found exactly what I was looking for in the Microsoft Products and Services Data Protection Addendum (DPA) — a legal document that confirms Microsoft’s data redundancy practices. If you’re looking for official proof, this is the document to consult (I’ll link it in the first comment).
In the DPA, Microsoft legally states that they maintain multiple copies of both Customer Data and Professional Services Data. These copies are stored in different locations from where the primary data processing takes place. This design is intended to ensure resilience and availability across regions, even in case of data center failures or regional outages.
Why This Legal Documentation Matters
- Multiple copies of data: The DPA confirms that Microsoft stores your data in various locations for added protection.
- Data stored separately from processing sites: Legal documentation guarantees that your data is backed up in different regions, providing security against localized failures.
- Ensured resilience and availability: This redundancy ensures minimal disruption, keeping your data safe and available even during regional issues.
If you’ve been searching for legal confirmation of Microsoft’s redundancy and resilience measures in M365, the DPA provides the hard proof you need. Microsoft’s commitment to data protection is not just a service promise—it’s legally documented.
