Introduction:
In the complex landscape of identity management, a single misconfigured Conditional Access policy or accidental deletion of a service principal can bring business-critical operations to a halt. Microsoft has introduced the public preview of Entra Backup and Recovery, a native solution designed to mitigate these risks by allowing administrators to restore core directory objects without relying on third-party tools or time-consuming manual recreation. This feature, available with Entra ID P1/P2 licenses, marks a significant shift in how organizations approach identity resilience, offering a safety net for users, groups, applications, and security policies.
Learning Objectives:
- Understand the capabilities and limitations of Microsoft Entra Backup and Recovery within the public preview scope.
- Learn how to restore critical directory objects, including Conditional Access policies and application configurations.
- Explore automation techniques and scripting methods to integrate backup and recovery workflows into existing security operations.
1. Restoring Core Directory Objects: A Step‑by‑Step Guide
The core functionality of Entra Backup and Recovery revolves around restoring objects from a rolling 5‑day backup window, with one backup snapshot retained per day. This section covers the manual restoration process for users, groups, and applications—a critical skill for rapid incident response.
Step‑by‑step guide:
- Access the Backup and Recovery Blade: Navigate to the Microsoft Entra admin center (
entra.microsoft.com). Under Identity, locate Backup and recovery in the left-hand navigation menu. - Select the Object Type: Choose the category of the deleted object—Users, Groups, Applications, or Service Principals.
- Identify the Deleted Item: Use the search bar or browse the list of objects deleted within the last 5 days. Click on the target object.
- Initiate Restore: Click the Restore button. A panel will appear showing available backup snapshots (usually the most recent backup within the 5‑day window).
- Confirm and Monitor: Click Confirm. The restore operation typically completes within minutes. Monitor the status via Azure Activity Logs or the notification center.
Administrative Context:
This process is invaluable for recovering from accidental deletions—a common scenario where an admin using PowerShell or the Graph API inadvertently removes a service principal tied to a critical SaaS application. While the preview supports only one backup per day, it provides a foundational safety net.
2. Recovering Conditional Access Policies and Security Configurations
Conditional Access policies are the gatekeepers of your Entra ID environment. A misconfigured policy can lock out administrators or expose resources. The new recovery feature allows for granular restoration of these policies, authentication method policies, authorization policies, and named locations.
Step‑by‑step guide:
- Navigate to Policy Restoration: In the Backup and recovery section, select Conditional Access policies.
- View Deleted or Overwritten Versions: The interface lists policies deleted within the retention period. Note: If a policy was modified (not deleted), you may need to compare recent changes manually or use the audit logs to identify the desired version.
- Select the Target Policy: Click on the policy name. The overview will show the JSON representation of the policy as it existed at the time of the backup.
- Execute Restore: Click Restore. The system will recreate the policy with the exact settings from the backup snapshot.
- Verify Immediately: After restoration, test the policy using the What If tool in Conditional Access to ensure it applies correctly without causing unintended access denials.
Technical Insight:
For automation-focused administrators, this restore operation can be performed via the Microsoft Graph API. A sample Graph API call to list deleted policies is:
PowerShell using Microsoft Graph Connect-MgGraph -Scopes "Policy.Read.All", "Policy.ReadWrite.ConditionalAccess" Get-MgDirectoryDeletedItem -DirectoryObjectId "policy-id"
This command is essential for scripting recovery workflows, especially in large enterprises where manual restoration is impractical.
- Automating Backup Awareness with the Microsoft Graph API
While the Entra Backup and Recovery feature handles the restore operations, proactive administrators can build monitoring and alerting around these backups using the Graph API. This allows for custom reporting on what is being backed up and who is performing restores.
Step‑by‑step guide:
- Obtain Required API Permissions: To query backup metadata, your application or script needs the `BackupRestore.Read.All` and `AuditLog.Read.All` delegated or application permissions.
- Construct a Graph Query: Use the following endpoint to retrieve backup events:
GET https://graph.microsoft.com/v1.0/auditLogs/directoryAudits?$filter=activityDisplayName eq 'Backup created'
- Parse the Output: The response will include JSON data detailing the object type, backup timestamp, and the initiating user. This can be ingested into a SIEM (Security Information and Event Management) like Microsoft Sentinel.
4. Create Alerts: Configure alerts for:
- Backup failures (indicated by `status` field in the audit log).
- Restores performed by non‑privileged accounts.
- Restores occurring outside of maintenance windows.
Windows Command (Azure CLI) Equivalent:
For administrators comfortable with Azure CLI, the same audit logs can be queried:
az monitor activity-log list --resource-group "YourResourceGroup" --query "[?contains(operationName.value, 'Backup')]"
This approach ensures that the backup and recovery service itself is monitored as part of your security posture.
4. Implementing Recovery Drills for Hybrid Environments
For organizations operating in a hybrid identity model (Entra ID Connect synchronizing from on-premises Active Directory), understanding the interplay between on-premises sources and cloud backups is critical. Restoring a synchronized user in Entra ID may conflict with the next synchronization cycle.
Step‑by‑step guide:
- Identify Source of Authority: Determine if the object to be restored originates from on-prem AD (cloud-only or hybrid). If hybrid, the source of authority is the on-premises domain controller.
- Temporarily Disable Synchronization: Before performing a restore of a hybrid object, consider placing the Entra ID Connect server in staging mode or disabling sync for the specific OU to prevent overwrites.
On the Entra ID Connect server, run as admin Set-ADSyncScheduler -SyncCycleEnabled $false
- Perform the Restore in Entra ID: Follow the steps in Section 1 to restore the user or group.
- Reconcile Attributes: After the restore, manually reconcile any attributes that may differ between on-prem AD and Entra ID.
- Re‑enable Synchronization: Re‑enable the sync cycle and monitor the delta sync to ensure no conflicts occur.
Set-ADSyncScheduler -SyncCycleEnabled $true Start-ADSyncSyncCycle -PolicyType Delta
Mitigation Strategy:
Regular recovery drills using this feature can reduce Mean Time to Recovery (MTTR) from hours to minutes. It also helps identify potential conflicts between hybrid synchronization and cloud-native recovery processes.
- Hardening Backup Access with Privileged Identity Management (PIM)
The ability to restore directory objects is a high‑privilege operation. To prevent malicious actors from abusing this feature, Microsoft integrates Entra Backup and Recovery with Privileged Identity Management (PIM). Administrators should not have standing access to restore operations.
Step‑by‑step guide:
- Assign Roles via PIM: Ensure that roles with permissions to manage backups (such as Global Administrator, Identity Governance Administrator, or Security Administrator) are eligible in PIM rather than permanently active.
- Require Just‑in‑Time (JIT) Access: Configure activation settings in PIM to require approval, multi‑factor authentication, and a business justification before an admin can perform a restore.
- Audit Restore Events: Regularly review the Directory Audit logs for `Restore` activity. A sample KQL query for Microsoft Sentinel is:
AuditLogs | where OperationName == "Restore" | project TimeGenerated, InitiatedBy, TargetResources
- Implement Break‑Glass Accounts: Maintain at least two cloud‑only break‑glass accounts that have permanent Global Admin access to ensure recovery is possible if PIM or Entra ID configuration is compromised.
Cloud Hardening Context:
This step aligns with the principle of least privilege and is a critical component of a Zero Trust identity strategy. By tightly controlling who can execute restores, organizations can prevent a compromised administrator account from silently reverting a malicious policy change.
What Undercode Say:
- Native Resilience is a Game‑Changer: The introduction of a native backup and recovery feature in Entra ID reduces dependency on costly third‑party backup tools and simplifies the disaster recovery process for identity management.
- Automation is Non‑Negotiable: While the GUI provides ease of use, integrating these recovery capabilities with the Graph API and audit logs is essential for large‑scale operations, enabling programmatic response to incidents like ransomware that targets identity configurations.
Analysis:
The Entra Backup and Recovery preview addresses a long‑standing gap in Microsoft’s identity platform. Previously, recovering a deleted Conditional Access policy or application involved cumbersome manual recreation, which was prone to error. This feature shifts the paradigm from reactive rebuilding to proactive restoration. However, the current limitation of a 5‑day retention period with only one backup per day means that organizations still need to consider additional protection for scenarios requiring point‑in‑time recovery beyond this window. The strategic value lies in its seamless integration with existing Entra tools like PIM and Graph API, allowing security teams to embed identity recovery into their broader incident response and disaster recovery plans.
Prediction:
As identity becomes the primary control plane for cloud security, we can expect Microsoft to rapidly evolve this feature, extending retention periods, enabling more frequent backups, and introducing granular item‑level recovery (e.g., restoring a single attribute of a user rather than the entire object). In the next 12–18 months, native identity backup will likely become a baseline security requirement for compliance frameworks, pushing organizations to adopt these features not as an option, but as a standard for cloud identity hygiene. The convergence of backup, identity governance, and security operations centers (SOCs) will accelerate, with automated recovery workflows becoming a staple in defending against identity‑based attacks.
