* Incremental Backups: Daily for all critical systems, capturing changes since the last backup.

* Differential Backups: Daily/Bi-daily for selected systems, capturing changes since the last full backup.

* Database Transaction Logs: Continuously shipped for Tier 0 databases to ensure near-zero data loss.

• Backup Frequency and Retention:

* Tier 0: Continuous data protection (CDP) or transactional log shipping, daily full, 7-day retention on-site, 30-day off-site.

* Tier 1: Daily incremental, weekly full. 14-day retention on-site, 90-day off-site. Monthly full for 1 year.

* Tier 2: Weekly full, daily incremental. 7-day retention on-site, 30-day off-site.

* Tier 3: Monthly full. 30-day retention off-site.

• Backup Locations:

* On-site: Primary backup repository for fast recovery of recent data.

* Off-site: Secure, geographically separate location (e.g., secondary data center, cloud storage) for disaster recovery.

* Cloud Storage: Encrypted and geo-redundant storage (e.g., AWS S3, Azure Blob Storage) for long-term retention and disaster recovery copies.

• Data Encryption: All data at rest (on backup media) and in transit (during backup transfer) is encrypted using industry-standard protocols (e.g., AES-256).
• Data Integrity Checks: Regular verification of backup integrity and restorability through automated tools and periodic test restores.
• Restoration Procedures:

* Detailed runbooks for restoring individual applications, databases, and servers.

* Prioritization of restoration based on RTO/RPO targets.

* Verification steps post-restoration to ensure full functionality.

8. Failover Procedures

The activation and execution of failover procedures are critical for rapid recovery.

• Activation Criteria:

* Declaration of a disaster by the DR Coordinator.

* Prolonged outage of critical systems at the primary site exceeding RTO thresholds.

* Physical damage to the primary data center.

* Regional disaster impacting the primary site.

• Failover Strategy:

* Hot Standby/Active-Active: For Tier 0 systems, immediate failover to a continuously synchronized secondary site.

* Warm Standby: For Tier 1 systems, pre-provisioned infrastructure at the secondary site, requiring minimal configuration and data synchronization.

* Cold Standby/Pilot Light: For Tier 2/3 systems, minimal infrastructure at the secondary site, requiring significant setup and data restoration.

• General Failover Steps:

1. Declare Disaster & Activate DRP: DR Coordinator initiates the plan.

2. Assess Damage & Isolate Primary Site: Prevent further data corruption.

3. Activate Recovery Site Infrastructure: Power on, configure network, security.

4. Restore Data: Restore databases and application data from the most recent valid backup/replica to the recovery site.

5. Restore Applications: Deploy and configure applications on the recovery site infrastructure.

6. Update DNS/Load Balancers: Redirect user traffic to the recovery site.

7. Perform Functional Testing: DR Team and Business Unit Liaisons verify system and application functionality.

8. Monitor Performance: Continuously monitor systems at the recovery site for stability and performance.

• Failback Procedures:

1. Assess Primary Site: Ensure the primary site is fully restored and stable.

2. Synchronize Data: Replicate data changes from the recovery site back to the primary site.

3. Schedule Failback: Plan for a controlled failback during a low-impact window.

4. Reverse DNS/Load Balancer Changes: Redirect traffic back to the primary site.

5. Verify Primary Site Functionality: Conduct full testing.

6. Deactivate Recovery Site: Power down/de-provision recovery resources.

9. Communication Plan

Effective communication is paramount during a disaster to manage expectations and provide timely information.

• Internal Communication (DR Team, Employees, Management):

* Initial Notification: DR Coordinator notifies DR team members via dedicated communication channels (e.g., SMS, emergency contact list, dedicated chat group).

* Status Updates: Regular updates (e.g., hourly, every 4 hours) provided to senior management and key stakeholders via email, dedicated communication platform, or conference calls.

* Employee Communication: General updates to all employees regarding operational status and expected recovery times, distributed via company-wide email, intranet, or designated hotline.

• External Communication (Customers, Vendors, Media, Regulatory Bodies):

* Customer Communication: Proactive updates via dedicated status page, email, or social media, informing them of the incident, impact, and estimated resolution time. Pre-approved templates available.

* Vendor Communication: Notify critical vendors (e.g., ISP, cloud providers, hardware support) to coordinate recovery efforts.

* Media Inquiries: All media inquiries are directed to the Communication Lead or designated spokesperson. Pre-approved press statements are available.

* Regulatory Bodies: Notify relevant regulatory authorities if required by law or compliance standards (e.g., data breach notification).

• Communication Channels:

* Primary: Dedicated Emergency Notification System (SMS, voice calls), Email (secondary system if primary is down).

* Secondary: Dedicated collaboration platform (e.g., Slack/Teams channel), Company Intranet (if available), Public Status Page.

* Offline: Printed contact lists and DRP documents.

10. Testing and Maintenance Schedule

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

• Types of Tests:

* Tabletop Exercises (Annually): A discussion-based session where the DR team walks through the plan, identifying gaps and validating procedures without actual system changes.

* Simulated Recovery Tests (Bi-Annually): Partial or full simulation of a disaster scenario in an isolated environment, testing specific components like backup restoration or application failover.

* Full Failover Tests (Annually for Tier 0/1, Bi-Annually for Tier 2): Actual failover to the recovery site, including DNS changes and full application functionality testing, followed by a planned failback. This is a disruptive test and requires careful planning.

• Testing Frequency:

* Tier 0/1 Systems: Full failover test annually. Simulated recovery tests bi-annually.

* Tier 2/3 Systems: Simulated recovery tests annually. Tabletop exercises annually.

* Backup Restoration Tests: Monthly verification of random data sets.

• Documentation of Test Results:

* Detailed reports for each test, including objectives, scope, participants, steps executed, issues encountered, lessons learned, and recommendations for improvement.

* Actionable items assigned with clear owners and deadlines.

• Review and Update Process:

* Formal Review (Annually): The entire DRP document is reviewed and updated by the DR team and senior management.

* Ad-hoc Updates: Updates are made whenever there are significant changes to infrastructure, applications, personnel, or business processes.
