Imagine a morning at the office: employees can’t log into email, business applications, CRM systems. Microsoft Teams is silent. SharePoint unavailable. The cause? An attack on Microsoft Entra ID - the central identity management system - or simply accidental deletion of critical objects by an administrator.
This scenario isn’t fiction. According to the Microsoft Digital Defense Report 2024, Entra ID is targeted by over 600 million attacks daily. In this article, we’ll explain why Microsoft Entra ID backup has become an essential element of security and business continuity strategy.

What is Microsoft Entra ID and why is it critical for business?
Microsoft Entra ID (formerly Azure Active Directory) is the central identity and access management (IAM) platform for the Microsoft ecosystem and beyond. It’s Entra ID that decides who can log into which resources in your organization.
What Entra ID manages:
- User accounts and their attributes
- Groups and memberships (security groups, M365 groups)
- App Registrations and Service Principals
- Conditional Access policies
- Administrative roles and permissions
- Single Sign-On to thousands of SaaS applications
Entra ID integrations:
- Microsoft 365 (Exchange, SharePoint, Teams, OneDrive)
- Azure cloud services
- Salesforce, Workday, ServiceNow
- Thousands of applications in the Azure AD gallery
- Custom applications via SAML/OIDC
Simply put: if Entra ID stops working or gets compromised, the entire organization halts. No login, no data access, no work.

Microsoft’s Shared Responsibility Model
Microsoft clearly communicates in documentation: protecting data in Entra ID is the customer’s responsibility. This is crucial information that many organizations ignore.
| Area | Microsoft’s Responsibility | Customer’s Responsibility |
|---|---|---|
| Infrastructure | ✓ 99.99% availability | - |
| Geo-redundancy | ✓ Replication between DCs | - |
| User data | - | ✓ Backup and recovery |
| Configuration | - | ✓ Policies, roles, groups |
| Accidental deletions | Partially (30 days) | ✓ Long-term protection |
| Ransomware/malware | - | ✓ Protection and recovery |
| Compliance | - | ✓ Log retention, audit |
Microsoft ensures infrastructure availability. But your data, configuration, and ability to recover them - that’s your responsibility.
What threats affect Entra ID?
Cyberattacks on identities
Statistics are alarming:
- 600 million identity attacks daily (Microsoft Digital Defense Report 2024)
- 277 days - average time to detect and contain a breach (IBM Security)
- 3x more identities to manage due to machine identity growth
Attackers know that the fastest way to compromise an organization is to take over an identity. An attack on Entra ID provides access to all connected systems.
Human errors and accidental deletions
Not all incidents are cyberattacks:
- An administrator accidentally deletes a group with 500 users
- A PowerShell script with a bug modifies attributes en masse
- A misconfigured Conditional Access policy blocks everyone
- Deletion of an App Registration used by a critical application
Misconfigurations
Configuration errors are one of the main incident vectors:
- Overly broad permissions for Service Principals
- No MFA for administrative accounts
- Outdated Conditional Access policies
- Legacy authentication enabled “temporarily”
Insider threats
An employee leaving (or being terminated) can:
- Delete or modify critical objects
- Export data before departure
- Leave a “backdoor” through a hidden App Registration
What Microsoft protects natively - and what it doesn’t
Microsoft Recycle Bin
Microsoft offers a Recycle Bin for deleted objects:
- Users: recoverable for 30 days
- M365 Groups: recoverable for 30 days
- Security Groups: NO soft-delete - deletion is permanent
- App Registrations: NO soft-delete
- Service Principals: NO soft-delete
Logs and audit
Microsoft stores logs for a limited time:
- Sign-in logs: 30 days (Entra ID P1/P2)
- Audit logs: 30 days (Entra ID P1/P2)
- Provisioning logs: 30 days
For compliance (GDPR, NIS2, DORA), retention of minimum 1-2 years is often required.
What Microsoft does NOT offer natively
- Point-in-time restore - you can’t go back to the state from a week ago
- Change detection - you can’t easily compare what changed
- Attribute backup - a restored user may not have all attributes
- Long-term log retention - max 30 days standard
- Forensic investigation - limited investigation capabilities
Why Recycle Bin isn’t enough
Scenario 1: Ransomware with delayed activation
Ransomware infects the environment but doesn’t activate immediately. For 45 days, it collects data and modifies configuration. After 30 days, objects “naturally” deleted by retention policies are unrecoverable from Recycle Bin.
Scenario 2: Attack on App Registration
An attacker compromises an App Registration used by a critical business application. They add additional credentials, modify permissions. App Registration has no Recycle Bin - after deletion (even by the attacker) it’s lost.
Scenario 3: Mass attribute modification
An administrator runs a script meant to change job titles for 10 people. Due to a filter bug, it changes 1000 people. Recycle Bin won’t help - objects weren’t deleted, just modified.
Scenario 4: Compliance audit
An auditor requests login logs from 6 months ago. Microsoft stores them for 30 days. Without external backup - you don’t have the data.
When is Entra ID backup essential?
Backup of Microsoft Entra ID should be a priority when:
Compliance requirements:
- DORA - Digital Operational Resilience Act for the financial sector
- NIS2 - cybersecurity directive
- GDPR - log retention and accountability
- ISO 27001 - business continuity management
Risk profile:
- Large organization (1000+ users)
- Complex environment with many App Registrations
- Integrations with critical business applications
- History of security incidents
- Financial sector, healthcare, critical infrastructure
Operational needs:
- Rapid recovery after incidents
- Forensic investigation capabilities
- Change tracking and audit
- Long-term log retention

Summary
Microsoft Entra ID is a critical IT infrastructure element for every organization using the Microsoft ecosystem. The shared responsibility model clearly indicates that protecting Entra ID data is your responsibility.
Microsoft’s native mechanisms (Recycle Bin, basic log retention) don’t provide:
- Long-term protection
- Point-in-time restore
- App Registrations protection
- Forensic capabilities
- Regulatory compliance
Facing 600 million daily attacks on identities, Microsoft Entra ID backup has stopped being optional - it has become an essential security strategy element.
