4. Disaster Scenario Activation Criteria

A disaster event is characterized by the unavailability of critical IT systems or infrastructure that significantly impacts business operations and cannot be resolved through standard operational recovery procedures.

4.1 Declaration Process

1. Initial Assessment (IT Operations/Help Desk): Upon detection of a major incident (e.g., widespread outage, data center failure, confirmed ransomware attack), IT Operations will conduct an immediate assessment to determine the scope and potential duration of the outage.
2. Notification to DR Coordinator: If the incident is deemed to exceed a predefined threshold (e.g., critical system down for >2 hours, primary data center inaccessible), the DR Coordinator must be notified immediately.
3. DR Coordinator Decision: The DR Coordinator, in consultation with executive management and relevant technical leads, will evaluate the situation against the activation criteria.
4. Disaster Declaration: If criteria are met, the DR Coordinator will formally declare a disaster, activate the DRP, and notify the DR Team.

4.2 Activation Criteria Examples

• Loss of primary data center facility (e.g., power, cooling, physical access).
• Catastrophic failure of core network infrastructure.
• Unrecoverable corruption or loss of critical production data.
• Widespread ransomware infection affecting critical systems.
• Major application outage exceeding [e.g., 4 hours] for a Tier 0/1 system.
• Any event where the RTOs of critical systems cannot be met through normal operational recovery.

5. Critical Systems and RTO/RPO Targets

The following table details critical systems, their criticality levels, business owners, and their respective Recovery Time Objectives (RTOs) and Recovery Point Objectives (RPOs). These targets dictate the urgency and strategy for recovery.

| System/Service Name | Criticality Level | Business Owner | RTO (Time) | RPO (Data Loss) | Dependencies | Recovery Strategy |

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

| Enterprise Resource Planning (ERP) | Tier 0 | Finance/Operations | 2 hours | 15 minutes | Database, Authentication, Network | Active-Passive DR site with database replication and VM snapshots. |

| Customer Relationship Management (CRM) | Tier 1 | Sales/Marketing | 4 hours | 1 hour | Database, Authentication, Web Servers | Active-Passive DR site with hourly database backups and VM replication. |

| E-commerce Platform | Tier 0 | Sales | 1 hour | 5 minutes | Database, Web Servers, Payment Gateway, CDN | Active-Active multi-region deployment with real-time data synchronization. |

| Email System (Exchange/O365) | Tier 1 | All Departments | 6 hours | 4 hours | Active Directory, Network, Storage | Cloud-native resilience (O365) or DR site for on-prem Exchange with DAG. |

| File Servers / SharePoint | Tier 2 | All Departments | 8 hours | 4 hours | Active Directory, Network, Storage | Daily backups to cloud storage with versioning; DR site VM restoration. |

| Active Directory | Tier 0 | IT Infrastructure | 2 hours | 30 minutes | Network, DNS, Domain Controllers | Multiple domain controllers in geographically separate locations; regular system state backups. |

| Core Network Infrastructure | Tier 0 | IT Infrastructure | 1 hour | N/A | Physical Hardware, ISP connectivity | Redundant hardware, redundant ISP links, pre-configured DR network appliances. |

Tier Definitions:

• Tier 0 (Mission Critical): Systems essential for immediate business operations. Downtime directly results in significant financial loss or regulatory non-compliance.
• Tier 1 (Business Critical): Systems important for daily operations. Downtime causes significant business disruption but may not halt all operations immediately.
• Tier 2 (Business Support): Systems that support business functions. Downtime is inconvenient but allows for manual workarounds or delayed processing.

6. Backup and Data Recovery Strategies

A robust backup strategy is fundamental to achieving RPO targets and ensuring data integrity.

6.1 Data Classification

• Critical Data: Data required for Tier 0/1 systems (e.g., transaction logs, customer databases). High RPO.
• Important Data: Data for Tier 2 systems (e.g., general files, internal reports). Moderate RPO.
• Non-critical Data: Data that can be easily recreated or is not essential for immediate recovery.

6.2 Backup Methods and Frequencies

• Databases (Tier 0/1):

* Method: Transaction log shipping/replication (e.g., SQL Server AlwaysOn, PostgreSQL streaming replication) for near real-time RPO.

* Frequency: Continuous for transaction logs; full backups daily; differential backups hourly.

* Retention: 7 days on-site, 30 days off-site/cloud.

• Virtual Machines (Tier 0/1/2):

* Method: Hypervisor-level snapshots/replication (e.g., VMware vSphere Replication, Azure Site Recovery).

* Frequency: Hourly snapshots for Tier 0/1; daily for Tier 2.

* Retention: 3-5 days of snapshots, weekly full VM backups for 4 weeks.

• File Servers:

* Method: Incremental backups with deduplication.

* Frequency: Daily.

* Retention: 30 days, with monthly full backups archived for 1 year.

• SaaS Applications (e.g., Salesforce, O365):

* Method: Utilize native backup/restore capabilities where available, or third-party SaaS backup solutions.

* Frequency: Daily.

* Retention: As per vendor/SLA or 90 days.

6.3 Backup Locations and Security

• On-site: Short-term backups for quick recovery of minor incidents.
• Off-site (Cloud Storage - e.g., AWS S3, Azure Blob Storage): Encrypted, geographically separate storage for long-term retention and disaster recovery. All cloud backups are encrypted in transit and at rest.
• Immutability: Critical backups stored in immutable storage to protect against ransomware and accidental deletion.

6.4 Backup
