Introduction to Microsoft 365 Backup Granular Restore
Microsoft is significantly enriching the capabilities of Microsoft 365 Backup with the introduction of granular restoration for files and folders in SharePoint and OneDrive. This feature, currently in public preview, revolutionizes the traditional data recovery approach by allowing administrators to restore specific items without impacting an entire site or account.
2026 Update
This feature addresses a growing demand from IT administrators seeking a more precise solution than complete SharePoint site or OneDrive account restoration for recovering individual items.
Evolution of Recovery Capabilities
Limitations of Traditional Methods
Until now, administrators faced two limited options:
- Complete Restore: Recovery of an entire SharePoint site or OneDrive account
- Microsoft 365 Recycle Bin: Limited recovery to 93 days with functional restrictions
These approaches proved particularly inefficient for targeted recovery scenarios, notably in cases of:
- Accidental deletion of critical documents
- Corruption of specific files
- Regulatory compliance requests
- Localized security incidents
Benefits of Granular Restoration
The new feature brings significant benefits:
- Precision: Exact selection of items to restore
- Efficiency: Significant reduction in recovery time
- Compliance: Appropriate response to personal and sensitive data requirements
- Resource Optimization: Minimization of infrastructure impact
Deployment Schedule and Availability
Rollout Phases
Public Preview
The public preview phase began in March 2026 and will continue until mid-March 2026. This period allows organizations to test the feature in their production environments.
General Availability
General availability deployment is planned from late April to early May 2026, ensuring gradual and controlled adoption.
Implementation Advice
Take advantage of the preview period to train your teams and adapt your recovery procedures to the new granular capabilities.
Technical and Administrative Prerequisites
System Requirements
To use granular restoration, your environment must meet several conditions:
| Component | Requirement | Impact |
|---|---|---|
| Azure License | Subscription with pay-as-you-go billing | Variable cost based on usage |
| Microsoft 365 Backup | Service activated at tenant level | Mandatory prior configuration |
| Permissions | SharePoint Backup Administrator role | Strict access control |
Roles and Permissions
The SharePoint Backup Administrator role is the minimum prerequisite for:
- Accessing restore points
- Browsing file hierarchies
- Initiating recovery operations
- Configuring destination settings
Step-by-Step Restore Process
Accessing the Restore Interface
Sign in to Admin Center
Access the Microsoft 365 admin center via https://admin.cloud.microsoft/ and authenticate with an account having appropriate permissions.
Navigate to Microsoft 365 Backup
In the Settings menu, select Microsoft 365 Backup to access backup and restore options.
Select Target Service
Choose Restore under the SharePoint or OneDrive section depending on your data source.
Configuring Granular Restore
Choose Restore Method
On the method selection page, opt for Restore specific files or folders to enable granular mode.
Select Resources
Identify the target OneDrive account or SharePoint site in the list of backed-up resources, then click Next.
Define Restore Point
Choose the appropriate date and time for restoration. The system automatically suggests the nearest restore point if no exact point exists.
Precise Item Selection
Browse Hierarchy
On the Content page, select the required sub-site then the target document library. Use the search function to quickly locate numerous libraries.
Search and Select
In the Select files and folders section, use the library-level search bar or manually browse the hierarchy to identify items to restore.
Validation and Launch
Check the required files and folders, then click Next. On the Review and Finalize page, verify your selection before clicking Start Restore.
Important Limitation
File selection is limited to the currently displayed folder hierarchy. Any search in another hierarchy will clear the current selection.
Advanced Technical Features
Restore Options
The feature offers two operational modes:
- In-place Overwrite: Direct restoration to the original location
- Copy to New Location: Creation of a copy in a different directory
Impact on Existing Architecture
The implementation respects several continuity principles:
- Policy Preservation: No impact on existing backup policies
- Backward Compatibility: Works with all existing restore points
- Granular Auditing: Extension of traceability to file and folder level
Architecture
This update affects neither the storage nor the location of backups. It only adds a layer of granular access to existing restore points.
