Is backup included in Microsoft 365?
Microsoft 365 offers built-in data protection through redundancy, version history, and recycle bin features, but it is not a full backup solution. Data is protected against disruption and certain types of loss, but businesses may need to supplement with external backup to meet internal requirements for recovery time, long-term storage and regulatory compliance.
What is included in Microsoft 365?
Microsoft 365 stores data in multiple data centers with geographic redundancy to protect against hardware failure and downtime.
Trash and recycling
Deleted emails, files and items can be recovered for a limited period of time via trash and restore functions.
Version history
SharePoint and OneDrive save previous versions of documents, making it possible to restore changes.
Retention policies
Using Microsoft Purview, organizations can create storage and retention policies to meet legal requirements.
High availability
Microsoft guarantees high uptime through cloud infrastructure with redundancy and failover systems.
Restrictions
Microsoft is responsible for the availability of the platform, while the customer is responsible for recovery in case of erroneous deletion, internal mistakes and certain types of cyberattacks.
External backup
Many companies choose to add third-party solutions for longer retention, faster recovery and extra protection against ransomware.
Difference between built-in protection and external backup
- Redundancy: Protect against disruptions and hardware failures.
- Recycle bin: Restore deleted items for a limited period.
- Version history: Restore previous document versions.
- Retention: Controls how long data is kept for compliance.
- External backup: Provides full recovery, longer history and an extra layer of security.
