4. DR Team Notification: DR Coordinator activates the communication plan (Section 8) to notify the DR team and key stakeholders.
5. Relocation (if necessary): If the primary facility is inaccessible, DR team members move to the designated DR command center or work remotely.

7.2. Failover Procedures (Example for a Critical Application - ERP System):

• DR Site: [e.g., Azure West US Region / Secondary Data Center]
• Target RTO: 4 hours
• Target RPO: 15 minutes

1. Verify DR Site Readiness (IT Infrastructure Lead):

* Confirm network connectivity between DR site and corporate VPN.

* Ensure virtual infrastructure (hypervisors, storage) is operational.

* Verify firewall rules and security groups are configured for ERP access.

1. Restore Core Network Services (Network Lead):

* Activate DR site VPN tunnels.

* Update DNS records (internal and external) to point to DR site IP addresses for ERP services (TTL reduced to 5 mins pre-disaster).

* Configure DR site load balancers/application gateways.

1. Restore Database Servers (Data & Database Lead):

* Provision new database server VMs at DR site if not pre-provisioned.

* Restore the latest full database backup.

* Apply incremental backups and transaction logs to achieve RPO.

* Perform database integrity checks and bring online.

1. Restore Application Servers (Applications Lead):

* Provision new application server VMs at DR site if not pre-provisioned.

* Restore the latest application server image/backup.

* Install and configure ERP application software.

* Update application configuration to point to the restored database.

1. Restore Web Servers (Applications Lead):

* Provision new web server VMs at DR site.

* Restore web application content and configurations.

* Configure web servers to connect to the DR application servers.

1. Functional Testing (Applications Lead, Business Continuity Lead):

* Perform internal functional tests of the ERP application.

* Engage key business users for user acceptance testing (UAT) of critical functions.

1. Service Go-Live (DR Coordinator):

* Once UAT is successful, DR Coordinator authorizes re-opening of services to end-users.

* Announce system availability via communication channels.

7.3. Data Synchronization and Failback Procedures:

1. Monitor Primary Site: Continuously monitor the primary site for recovery and stability.
2. Replication Setup: Once the primary site is stable, establish reverse replication from the DR site back to the primary site.
3. Delta Synchronization: Allow sufficient time for all changes made at the DR site to synchronize back to the primary site.
4. Failback Planning: Schedule the failback during a low-impact maintenance window.
5. Failback Execution:

* Briefly halt services at the DR site.

* Verify data consistency on the primary site.

* Switch DNS entries and network routes back to the primary site.

* Perform functional testing on the primary site.

1. Post-Failback: Decommission temporary DR resources and revert configurations.

8. Communication Plan

Effective communication is critical during a disaster. This plan defines how information will be disseminated internally and externally.

8.1. Internal Communication (DR Team, Employees, Management):

• Initial Notification: SMS, dedicated crisis communication app (e.g., PagerDuty, Everbridge), and personal phone calls to DR team members within 15 minutes of declaration.
• Regular Updates: Hourly updates to the DR team and executive management via conference calls, dedicated chat channels, or a crisis management portal.
• Employee Communication: Regular updates to all employees (e.g., every 2-4 hours) via company-wide email, intranet portal, or dedicated status page, informing them of system status and expected recovery times.
• Pre-approved Templates: Utilize pre-approved communication templates for various stages of the disaster (e.g., "Incident Declared," "Recovery in Progress," "Services Restored").

8.2. External Communication (Customers, Partners, Vendors, Media, Regulatory Bodies):

• Customers:

* Initial Notification: Public status page, email blast, and social media updates within 1 hour of impact, confirming an issue and that recovery efforts are underway.

* Regular Updates: Every 2-4 hours via status page, email, and social media, providing progress updates and estimated resolution times.

* Resolution Notification: Final notification once services are fully restored.

• Partners/Vendors: Direct email and phone calls from the Communications Lead to critical partners/vendors, informing them of the situation and potential impact on shared services.
• Media: All media inquiries must be directed to the Communications Lead. Only pre-approved statements will be issued.
• Regulatory Bodies: If required, the Legal/Compliance team (in coordination with the Communications Lead) will notify relevant regulatory bodies within the specified timeframe (e.g., 72 hours for data breaches under GDPR).

8.3. Communication Channels and Tools:

• Primary: Dedicated crisis management platform (e.g., Microsoft Teams, Slack with dedicated channels), conference bridge, SMS alerts.
• Secondary: Personal mobile phones, satellite phones (for extreme scenarios).
• Public Status Page: [URL to Status Page]
• Emergency Contact List: Stored off-site and in a secure, accessible cloud location.

9. Testing and Maintenance Schedule

Regular testing and continuous maintenance are crucial to ensure the DRP remains effective and current.

9.1. Types of Tests:

• Tabletop Exercises (Quarterly): Discussion-based walk-through of the
