6. Failover Procedures

These procedures detail the steps to switch operations from the primary site to the designated Disaster Recovery (DR) site.

6.1. Activation Criteria

Failover will be initiated upon:

• Unavailability of the primary data center for a predefined period (e.g., 30 minutes for Tier 0/1 systems).
• Catastrophic failure of critical infrastructure at the primary site.
• Declaration of disaster by the Disaster Recovery Team Lead.

6.2. Step-by-Step Failover Process

1. Declare Disaster: Incident Commander officially declares a disaster and activates the DRP.
2. Notify DR Team: All DR team members are notified via primary and secondary communication channels.
3. Assess Damage: Initial assessment of primary site damage and impact on RTO/RPO.
4. Initiate Failover Sequence (Automated/Manual):

* Network:

* Update DNS records to point to DR site IP addresses (TTL set low).

* Activate DR site network infrastructure (firewalls, routers, load balancers).

* Establish VPN tunnels if required for remote access.

* Compute:

* Power on/provision virtual machines/instances at the DR site.

* Restore system configurations and operating systems (if not pre-provisioned).

* Data:

* Promote DR site databases to primary status.

* Restore most recent data from replication or backups as per RPO.

* Ensure data consistency and integrity.

7.3. Escalation Matrix

A clear matrix outlining when and to whom specific issues or prolonged outages should be escalated, up to executive leadership.

8. Testing and Maintenance Schedule

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

8.1. Types of Testing

• Tabletop Exercises (Annually): A discussion-based session where the DR team walks through the plan, identifying gaps and areas for improvement.
• Simulated Testing (Bi-annually): Partial or full simulation of a disaster scenario without impacting production systems. This might involve restoring data to a test environment or simulating a network outage.
• Full Cutover Testing (Annually/Bi-annually): A complete failover to the DR site, with actual production traffic being routed to the DR environment. This is the most comprehensive test and requires careful planning and rollback procedures.

8.2. Testing Frequency

• Tabletop Exercises: Annually
• Simulated Tests: Bi-annually (e.g., alternating between data recovery and application failover)
• Full Cutover Tests: Annually (or every 18 months, depending on business criticality and complexity)
• Backup Restoration Tests: Monthly (random selection of backups to ensure recoverability)

8.3. Documentation of Test Results

• All test results, observations, lessons learned, and identified deficiencies will be documented.
• Action plans will be created to address any issues found during testing.

8.4. Review and Update Process

6. Backup and Data Recovery Strategies

Our strategy focuses on a multi-layered approach to data protection, ensuring redundancy and recoverability.

6.1. Backup Types and Frequency

• Full Backups: Weekly, for all critical systems and data.
• Incremental Backups: Daily, capturing changes since the last full or incremental backup.
• Differential Backups: Not currently utilized, but an option for future consideration if deemed more efficient for specific datasets.
• Database Transaction Logs: Continuously shipped/replicated for critical databases to achieve near-zero RPO.
• Snapshots: Regular VM and volume snapshots for rapid recovery of entire systems.

6.2. Backup Storage Locations and Retention

• On-site Storage: Short-term backups (daily/weekly) stored on a dedicated NAS/SAN for quick recovery of recent data. Retention: 7 days.
• Off-site Storage: Encrypted backups replicated to a secure off-site data center (e.g., secondary cloud region or co-location facility). Retention: 30 days.
• Cloud Storage: Long-term archives (monthly/quarterly) stored in immutable object storage (e.g., AWS S3 Glacier, Azure Blob Archive). Retention: 1 year for compliance, 7 years for specific regulatory data.

6.3. Data Encryption and Integrity

• All data at rest (on-site, off-site, cloud) is encrypted using AES-256 encryption.
• All data in transit (during replication or transfer) is secured via TLS 1.2+.
• Regular integrity checks (e.g., checksums, test restores) are performed on backups to ensure data recoverability.

6.4. Data Restoration Procedures

1. Identify Data Loss/Corruption: Determine the extent and timeframe of data loss.
2. Locate Backup: Identify the appropriate backup set (full, incremental, transaction logs) based on the required RPO.
3. Restore to Staging Environment: For critical systems, restore data to a segregated staging environment first to verify integrity and functionality.
4. Perform Actual Restore: Once verified, initiate the restore to the production environment or recovery site.
5. Post-Restore Validation: Verify data consistency, application functionality, and user access.

7. Disaster Declaration and Activation Procedures

7.1. Criteria for Declaring a Disaster

A disaster is declared when an incident severely impacts critical business operations, exceeds the capabilities of standard incident response, and is expected to violate defined RTOs/RPOs. Examples include:

• Major data center outage (power, network, environmental).
• Catastrophic hardware failure impacting multiple critical systems.
• Wide-scale cyber-attack (ransomware, data breach) rendering systems unusable.
• Natural disaster (fire, flood, earthquake) affecting primary facilities.
• Prolonged regional network outage.

7.2. Notification Process

1. Initial Assessment: DRP Coordinator (or designated alternate) assesses the situation based on input from technical teams.
2. Disaster Declaration: DRP Coordinator declares a "Disaster" status, initiating the DRP.
3. DRT Notification: All DRT members are immediately notified via multiple channels (e.g., primary: SMS alert system, secondary: dedicated conference bridge, tertiary: email).
4. Executive Notification: Executive management is informed of the disaster declaration and initial impact.

7.3. Activation of the DRP Team

Upon notification, DRT members will:

1. Acknowledge receipt of the disaster notification.
2. Join the designated emergency communication channel (e.g., conference bridge, dedicated chat room).
3. Assemble at the designated command center (physical or virtual).
4. Receive initial briefing from the DRP Coordinator.
5. Begin executing their assigned roles and procedures outlined in this plan.

8. Failover and Recovery Procedures

The recovery process is structured into phases to ensure an orderly and efficient restoration of services.

8.1. Phase 1: Damage Assessment & Initial Response

1. Incident Confirmation: Confirm the nature, scope, and severity of the disaster.
2. Impact Analysis: Identify affected systems, data, and business functions.
3. Isolate Affected Systems: Take immediate steps to contain the damage (e.g., disconnect infected systems, power down faulty hardware).
4. Determine Recovery Strategy: Decide whether to recover in place (if primary site is viable) or failover to the designated recovery site.

8.2. Phase 2: Recovery Site Activation (if failover is necessary)

1. Activate Secondary Infrastructure:

* Provision necessary compute resources (VMs, containers) in the recovery data center or cloud region.

* Configure network connectivity, firewalls, and VPNs to match the primary environment.

* Ensure DNS updates are initiated to direct traffic to the recovery site (TTL considerations).

1. Verification of Recovery Environment:

* Confirm basic network connectivity and access to the recovery site.

* Verify resource allocation and configuration.

8.3. Phase 3: System Restoration & Data Recovery

1. Restore Core Infrastructure Services (P1 - RTO: 2-4 hours):

* Directory Services (e.g., Active Directory, LDAP).

* DNS Servers.

* Network Management Tools.

* Security Monitoring Systems.

1. Restore Critical Databases (P1 - RPO: 5-15 minutes):

* Restore the most recent verified backup.

* Apply transaction logs to achieve target RPO.

* Verify database integrity and connectivity.

1. Restore Mission-Critical Applications (P1 - RTO: 4 hours):

* Restore application servers (from VM snapshots or bare-metal backups).

* Install and configure application software.

* Connect applications to restored databases.

* Perform initial functional tests.

1. Restore Business-Critical Applications (P2 - RTO: 8-12 hours):

* Follow similar steps as mission-critical applications, prioritizing based on RTO.

1. Restore Business Support Systems (P3 - RTO: 24-48 hours):

* Restore remaining applications and services.

8.4. Phase 4: Verification & Testing

1. Internal Functional Testing: DRT and technical teams perform comprehensive tests of all restored systems and applications.

* Login functionality, data retrieval, transaction processing.

* Integration points between applications.

1. User Acceptance Testing (UAT): A designated group of business users performs UAT to validate business processes and data integrity.
2. Security Audit: Conduct a quick security audit to ensure no new vulnerabilities were introduced during recovery.
3. Performance Monitoring: Monitor system performance and resource utilization to ensure stability.

8.5. Phase 5: Failback Procedures (Return to Primary Site - if applicable)

If the primary site becomes operational and stable, a planned failback will be executed.

1. Assess Primary Site Readiness: Ensure all issues at the primary site are resolved and infrastructure is fully functional.
2. Data Synchronization: Synchronize all data changes from the recovery site back to the primary site. This is a critical step to prevent data loss.
3. Test Primary Site: Perform thorough testing of the primary site with synchronized data.
4. Planned Cutover: Schedule a planned maintenance window for the cutover.
5. DNS Re-pointing: Update DNS records to direct traffic back to the primary site.
6. Deactivate Recovery Site: Once the primary site is stable and verified, the recovery site resources can be de-provisioned or scaled down.
7. Post-Failback Review: Conduct a review to document lessons learned from the failback process.

9. Communication Plan

Effective communication is paramount during a disaster. This plan outlines internal and external communication strategies.

9.1. Internal Communication

• DRT Members: Dedicated conference bridge, secure chat channel (e.g., Slack/Teams channel), SMS alerts. Updates every 30-60 minutes during active recovery.
• Employees:

* Initial Notification: Broad communication via email (if available), SMS, and company status page (if external provider).

* Status Updates: Regular updates (e.g., every 2-4 hours) on the company status page and via email.

* Return to Work/Service Availability: Clear instructions on when and how to resume work.

• Executive Management: Direct briefings from DRP Coordinator, typically every 1-2 hours or as significant milestones are reached.

9.2. External Communication

• Customers:

* Initial Notification: Public status page, social media (if appropriate), mass email for critical service outages. Focus on acknowledging the issue and providing estimated restoration times if known.

* Status Updates: Regular updates (e.g., every 2-4 hours) via the public status page and social media.

* Resolution Notification: Inform customers when services are fully restored.

• Vendors/Partners: Direct contact by the Business Operations Lead or Technical Lead as needed for support, service
