3. Key Definitions & Terminology

• Disaster Recovery Plan (DRP): A documented process or set of procedures to recover and protect a business IT infrastructure in the event of a disaster.
• Recovery Time Objective (RTO): The maximum tolerable duration of time that a computer, system, network, or application can be down after a failure or disaster before business operations are significantly impacted.
• Recovery Point Objective (RPO): The maximum tolerable amount of data that can be lost from an IT service due to a major incident. It represents the age of the files or data in backup storage required to resume normal operations.
• DR Site (Disaster Recovery Site): A secondary location where business operations can continue after a disaster. Can be hot, warm, or cold.
• Failover: The process of switching automatically or manually to a redundant or standby computer server, system, hardware component, or network upon the failure or abnormal termination of the previously active application, server, system, hardware component, or network.
• Failback: The process of restoring systems and data to the primary operational site after a disaster has been mitigated and the primary site is fully restored.
• Business Continuity Plan (BCP): A holistic plan that outlines how an organization will continue to operate during and after a disruptive event. The DRP is a component of the BCP.
• Critical Systems: Systems, applications, and data identified as essential for the continued operation of core business functions.

| System/Application Group | Description | RTO Target | RPO Target | Backup Strategy | DR Site Type |

| :----------------------- | :---------- | :--------- | :--------- | :-------------- | :----------- |

| Tier 1: Mission-Critical | Core E-commerce, ERP (Finance, Inventory), CRM, Primary Databases | < 4 Hours | < 1 Hour | Real-time Replication + Incremental Backups | Hot Site (Active-Passive or Active-Active) |

| Tier 2: Business-Critical | Email/Communication, HR Systems, Development Environments, Reporting Tools | < 8 Hours | < 4 Hours | Daily Incremental + Weekly Full Backups | Warm Site |

| Tier 3: Supporting | Internal File Servers, Non-critical Intranet, Legacy Applications | < 24 Hours | < 24 Hours | Daily Full Backups | Cold Site / Cloud Object Storage |

Note: Specific RTO/RPO for individual applications within these tiers are detailed in Appendix B (System Criticality Matrix).

6. Backup and Data Recovery Strategies

A multi-layered backup strategy ensures data availability and recoverability across different disaster scenarios.

6.1. Backup Types and Frequency

• Full Backups: Weekly for all systems, stored off-site.
• Incremental Backups: Daily for all systems, capturing only changes since the last full or incremental backup.
• Differential Backups: Not currently utilized, but may be considered for specific large datasets if incremental recovery time becomes an issue.
• Database Transaction Logs: Continuously shipped/replicated for Tier 1 databases to achieve near-zero RPO.
• Cloud Snapshots: Daily snapshots for critical cloud instances (VMs, databases).

6.2. Backup Retention Policies

• Daily Incremental/Differential: 30 days
• Weekly Full: 90 days
• Monthly Full: 1 year
• Yearly Full (Archival): 7 years (for regulatory compliance)

6.3. Backup Storage Locations

• On-site (Primary): Short-term recovery, high-speed access.
• Off-site (Secondary): Secure, geographically separate facility for disaster recovery. Data encrypted in transit and at rest.
• Cloud Storage (Tertiary): Encrypted object storage (e.g., AWS S3, Azure Blob) in a separate region for long-term archival and geographic diversity.

6.4. Data Encryption

All backups, whether in transit or at rest, are encrypted using AES-256 encryption. Encryption keys are managed securely and stored separately from the backup data.

6.5. Data Recovery Procedures

1. Identify Recovery Point: Determine the latest valid RPO based on the disaster's impact.
2. Locate Backups: Retrieve necessary backups from primary, secondary, or cloud storage.
3. Restore Order: Prioritize restoration of operating systems, then core applications, then data.
4. Data Integrity Check: Perform checksums and application-level verification after restoration.
5. Validation: Business unit liaisons validate data and application functionality.

7. Failover and System Recovery Procedures

These procedures detail the steps to activate the DR site and restore critical systems.

7.1. Disaster Declaration and Activation

1. Detection: Monitoring systems, alerts, or manual reporting indicate a critical incident.
2. Assessment: DR Coordinator, in consultation with IT Leads, assesses the scope and impact of the disaster.
3. Declaration: DR Coordinator officially declares a disaster based on predefined criteria (e.g., primary data center unavailable for > 2 hours).
4. Team Notification: DR Coordinator activates the DR team via emergency communication channels (SMS, dedicated calling tree).
5. Go/No-Go Decision: Executive management approves the DRP activation.

7.2. Primary System Shutdown/Isolation

• If feasible and safe, gracefully shut down affected primary systems to prevent further data corruption.
• Isolate compromised systems from the network to prevent malware spread or further unauthorized access.

7.3. DR Site Activation (Cloud-based Hot/Warm Site)

1. Infrastructure Provisioning:

* Activate pre-configured cloud DR environment (e.g., AWS CloudFormation, Azure Resource Manager templates).

* Verify network connectivity, VPNs, and security groups.

* Provision necessary compute instances, databases, and storage.

1. Data Synchronization/Replication:

* Verify replication status for Tier 1 systems (e.g., database replication, block-level storage replication).

* Initiate data restoration from the latest backups for Tier 2 and 3 systems.

1. Application Deployment/Configuration:

* Deploy application code from version control repositories to DR instances.

* Configure application settings, environment variables, and database connection strings.

* Update DNS records (e.g., A records, CNAMEs) to point to DR site IP addresses or load balancers. TTLs should be low for critical services.

* Configure load balancers and firewalls in the DR environment.

1. System Verification:

* Perform smoke tests on all critical applications and services.

* Verify data consistency and integrity.

* Conduct user acceptance testing (UAT) with business unit liaisons.

7.4. Failback Procedures (Return to Primary Site)

Once the primary site is fully restored and deemed stable:

1. Primary Site Restoration: Ensure all primary infrastructure, networking, and security components are fully operational.
2. Data Synchronization: Replicate all data changes from the DR site back to the primary site. This often requires a "reverse replication" or a carefully planned data export/import.
3. Testing Primary Site: Thoroughly test all systems and applications on the primary site using current data.
4. Scheduled Cutover: Plan a scheduled maintenance window for the failback.
5. DNS Reversion: Update DNS records to point back to the primary site.
6. Deactivation of DR Site: Once the primary site is confirmed stable and operational, gracefully shut down DR resources to minimize costs.

8. Communication Plan

Effective communication is paramount during a disaster to manage expectations, coordinate efforts, and maintain confidence.

8.1. Internal Communication

• DR Team:

* Initial Notification: Automated SMS/email alerts, dedicated conference bridge.

* Ongoing Updates: Regular conference calls (e.g., every 2 hours during active recovery), dedicated chat channel (e.g., Slack/Teams).

* DR Coordinator: Central point of contact for all team communications.

• Employees:

* Initial Notification: Email (if available), dedicated emergency hotline, company intranet (if accessible), SMS.

* Status Updates: Regular updates on service availability, expected recovery times, and alternative work arrangements.

* Communication Lead: Responsible for drafting and distributing internal communications.

• Executive Management:

* Initial Notification: DR Coordinator provides immediate briefing.

* Regular Briefings: Structured updates (e.g., hourly, then every 4 hours) on impact, recovery progress, and projected timelines.

8.2. External Communication

• Customers:

* Initial Notification: Public status page, email (for critical services), social media (if appropriate).

* Status Updates: Regular updates via status page and email. Transparency regarding impact and recovery efforts.

* Pre-approved Templates: Utilize pre-approved communication templates for various scenarios.

• Vendors/Partners:

* Notification: Direct email or phone calls to critical service providers (e.g., ISP, cloud provider, hardware support).

* Coordination: Work closely with vendors for support and service restoration.

• Regulatory Bodies/Media:

* Notification: Only as required by law or company policy. All media inquiries must be directed to the designated Communications Lead or PR department.

* Legal/Compliance Review: All external communications related to legal or regulatory matters must be reviewed by legal counsel.

8.3. Communication Channels

• Primary: Email (secondary domain if primary is down), dedicated emergency phone line, SMS/Text messaging.
• Secondary: Public status page, company website (static disaster page), designated social media accounts.
• Tools: PagerDuty, Everbridge, or similar incident management/mass notification systems.

9. Testing and Maintenance Schedule

Regular testing and maintenance are crucial to ensure the DRP remains effective and up-to-date.

9.1. Testing Types and Frequency

• Tabletop Exercises (Annual): Review the plan verbally, walk through scenarios with the DR team, identify gaps in procedures or understanding.
• Simulated Failover Tests (Bi-Annual): Simulate a disaster scenario by failing over non-production or isolated production systems to the DR site. Verify functionality without impacting live services.
• Full-Scale DR Tests (Annual for Tier 1 systems, Bi-Annual for Tier 2): Perform a complete failover of production systems to the DR site. This may involve a planned outage. Validate R
