6. Backup and Data Recovery Strategy

A robust backup strategy is central to achieving defined RPOs and ensuring data integrity.

6.1. Data Classification

All data is classified based on sensitivity, criticality, and regulatory requirements (e.g., Public, Internal, Confidential, Restricted). This classification dictates backup frequency, retention, and encryption methods.

6.2. Backup Methodologies

• Full Backups: Performed weekly for all critical systems. A complete copy of all selected data is made.
• Incremental Backups: Performed daily for critical systems. Only data that has changed since the last full or incremental backup is saved. Faster backup, slower restore.
• Differential Backups: Performed daily for non-critical systems. All data changed since the last full backup is saved. Slower backup than incremental, faster restore.
• Database Transaction Logs: Continuously backed up (log shipping/replication) for critical databases to ensure near-zero data loss (RPO < 1 hour).
• Snapshots: Used for virtual machines and storage arrays for rapid recovery from minor incidents, not as a primary DR backup.

6.3. Backup Frequency and Retention

| System/Data Type | Backup Type | Frequency | Retention Period |

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

| Critical Databases | Full, Log | Weekly, Continuous | 7 years (regulatory), 30 days operational |

| Primary CRM Data | Full, Incremental | Weekly, Daily | 1 year, 90 days operational |

| ERP Application/Data | Full, Incremental | Weekly, Daily | 7 years (regulatory), 90 days operational |

| File Servers | Full, Incremental | Weekly, Daily | 90 days, 7 years for specific archived data |

| VM Images | Full | Monthly | 6 months |

6.4. Backup Storage Locations

• On-site Storage: Short-term retention of recent backups for rapid recovery from minor failures. Stored in a fire-resistant safe.
• Off-site Storage: Encrypted backups transferred daily to a secure, geographically separate location ([e.g., Azure Blob Storage, AWS S3, dedicated DR site]). This protects against site-wide disasters.
• Cloud Storage: Utilized for long-term archival and as a primary off-site repository for critical system backups, leveraging geo-redundant storage options.

6.5. Data Encryption

All data backups, both in transit and at rest, are encrypted using AES-256 encryption keys managed securely.

6.6. Recovery Procedures for Backups

1. Identify Required Backup: Determine the specific backup (full, incremental, differential) and point-in-time needed based on RPO.
2. Locate Backup Media/Location: Retrieve from on-site, off-site, or cloud storage.
3. Restore to Staging Area: Restore data to a segregated staging environment to verify integrity and prevent contamination of production.
4. Verify Data Integrity: Perform checksums, database consistency checks, and application-level validation.
5. Move to Production (if necessary): Once verified, move the restored data to the production environment or DR site.
6. Post-Recovery Tasks: Update indexes, run integrity scripts, notify users.

7. Disaster Detection and Declaration

7.1. Criteria for Disaster Declaration

A disaster is declared if any of the following conditions are met:

• Loss of primary data center facility due to fire, flood, or other catastrophic event.

4. Recovery Time Objective (RTO) and Recovery Point Objective (RPO) Targets

RTO and RPO targets are defined based on the Business Impact Analysis (BIA) to prioritize recovery efforts and minimize business disruption and data loss.

• Recovery Time Objective (RTO): The maximum tolerable duration of time that a computer, system, application, or network can be down after a disaster or disruption before operations are severely impacted.
• Recovery Point Objective (RPO): The maximum tolerable period in which data might be lost from an IT service due to a major incident. This is determined by the last valid data backup.

Critical Systems RTO/RPO Matrix:

| System/Application Category | Example Systems/Applications | RTO Target | RPO Target | Justification |

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

| Tier 0: Mission-Critical | Core Transaction Processing, Customer Facing Portals, Primary Database Servers | < 4 hours | < 1 hour | Immediate and severe financial/reputational impact if unavailable or data lost. |

| Tier 1: Business-Critical | ERP System, CRM, Email/Communication, Collaboration Tools, Directory Services (AD) | 4-8 hours | < 4 hours | Significant operational disruption, potential revenue loss, and customer dissatisfaction. |

| Tier 2: Business-Support | Internal Reporting, Development Environments, HR Systems, File Shares | 8-24 hours | < 12 hours | Operational inefficiencies, but business can function with manual workarounds temporarily. |

| Tier 3: Non-Critical | Test Environments, Archival Systems, Non-essential Intranet Sites | > 24 hours | < 24 hours | Minimal immediate business impact, can tolerate extended downtime. |

Note: Specific RTO/RPO targets for individual applications are documented in the System Inventory and Application Dependency Matrix (Appendix A).

5. Disaster Declaration Criteria and Incident Escalation

A disaster is declared when an incident exceeds the capabilities of standard incident response procedures and significantly impacts critical business functions, requiring activation of the DRP.

Disaster Declaration Criteria:

• Prolonged Outage: Expected downtime of a Tier 0 or Tier 1 system exceeding its RTO.
• Widespread Impact: Multiple critical systems or a primary data center are rendered inoperable.
• Data Loss/Corruption: Significant data loss or corruption impacting critical data beyond RPO targets.
• Facility Unavailability: Primary operational facility is inaccessible or unusable.
• Security Breach: A major cyber-attack compromising critical infrastructure and data integrity.

Escalation Process:

1. Incident Detection: Monitoring systems, user reports, security alerts.
2. Initial Assessment (IRT): The Incident Response Team assesses the scope, impact, and estimated recovery time.
3. Escalation to DR Coordinator: If the incident meets disaster declaration criteria, the IRT escalates to the DR Coordinator.
4. Disaster Declaration: The DR Coordinator, in consultation with senior management, formally declares a disaster and activates the DRP.
5. Team Mobilization: All relevant DR teams are notified and mobilized.

6. Backup Strategies

Robust backup strategies are fundamental to meeting RPO targets and ensuring data recoverability.

6.1. Data Backup Strategy:

• Critical Data Identification: All data identified as Tier 0 and Tier 1 is prioritized for backup.

* Differential Backups: Daily for critical systems and data.

* Incremental Backups: Hourly/Continuous Data Protection (CDP) for Tier 0 databases and file shares.

• Backup Frequency:

* Tier 0/1 Databases: Transaction logs shipped every 15 minutes, full backup daily.

* Tier 0/1 File Servers: Hourly snapshots, daily differential, weekly full.

* Virtual Machine Images: Daily snapshots/backups.

• Retention Policies:

* Daily backups: 7 days

* Weekly backups: 4 weeks

* Monthly backups: 12 months

* Annual backups: 7 years

• Storage Locations:

* On-site (Primary): For rapid recovery of minor incidents.

* Off-site (Secondary): Encrypted, geographically separate, air-gapped storage for disaster recovery.

* Cloud (Tertiary): Encrypted and immutable backups leveraging cloud object storage for long-term retention and resilience.

• Encryption: All backups, both in transit and at rest, are encrypted using AES-256.
• Integrity Checks: Regular verification of backup integrity and restorability through automated checks and periodic test restores.

6.2. System and Application Backup Strategy:

• Virtual Machine Backups: Full VM image backups are taken daily and replicated to the recovery site.
• Database Backups: Native database backups (SQL Server, Oracle, PostgreSQL) are configured with transaction log shipping/replication for critical databases to ensure low RPO.
• Configuration Backups: Network device configurations, firewall rules, and critical application configurations are backed up nightly and stored securely off-site.
• Code Repositories: All source code and development assets are stored in geographically redundant version control systems (e.g., Git repositories).

7. Recovery Sites

PantheraHive utilizes a hybrid recovery site strategy to balance cost and recovery speed:

• Primary Recovery Site (Warm Site):

* Location: Geographically distinct from the primary data center (e.g., separate availability zone or region).

* Infrastructure: Partially equipped with essential hardware (servers, storage, network gear), pre-configured with network connectivity, and ready for rapid provisioning.

* Data: Replicated data from primary site, requiring some synchronization upon activation.

* Purpose: To serve as the immediate failover target for Tier 0 and Tier 1 systems.

• Cloud-based Recovery (DRaaS - Disaster Recovery as a Service):

* Provider: [Specify Cloud Provider, e.g., AWS, Azure, Google Cloud]

* Strategy: Utilizing cloud services for replication and recovery of virtual machines and databases, offering on-demand infrastructure scaling.

* Purpose: Provides an alternative recovery location, particularly for long-term recovery or for systems where the warm site might be insufficient. Cost-effective for less frequently used DR scenarios.

8. Failover Procedures

Failover procedures are the core operational steps to shift production from the primary site to the recovery site.

8.1. Pre-Failover Activities:

1. Confirm Disaster Declaration: DR Coordinator formally declares a disaster.
2. Assemble DR Teams: Notify and convene relevant technical teams.
3. Review DRP & Checklists: Ensure all teams have access to the latest DRP and specific recovery runbooks.
4. Isolate Primary Site (if applicable): Disconnect the primary site from the network to prevent data corruption or split-brain scenarios, especially in cases of cyber-attack.

8.2. Failover Execution Steps:

• Step 1: Network Infrastructure Activation (Recovery Site - 30 minutes)

* Activate network infrastructure at the recovery site (routers, switches, firewalls).

* Verify network connectivity to the internet and between DR network segments.

* Update DNS records (internal and external) to point to recovery site IPs. TTLs should be set to minimum in advance.

* Establish VPN tunnels to necessary third-party services/vendors.

• Step 2: Core Services Recovery (Recovery Site - 1 hour)

* Restore/activate Directory Services (e.g., Active Directory Domain Controllers) from replicated images/backups.

* Verify DNS resolution and authentication services.

* Bring up essential network services (DHCP, NTP).

• Step 3: Database Recovery (Recovery Site - Priority Based on RPO/RTO)

* For replicated databases (e.g., SQL AlwaysOn, Oracle Data Guard): Initiate failover to the secondary replica at the recovery site.

* For backup-based recovery: Restore the latest full backup, then apply differential and transaction log backups to meet RPO.

* Perform database integrity checks and bring databases online.

• Step 4: Application Server Recovery (Recovery Site - Priority Based on RPO/RTO)

* Power on/provision virtual machines for Tier 0 applications.

* Restore application binaries and configurations (if not part of VM image).

* Start application services in the defined dependency order.

* Configure load balancers to direct traffic to the recovered application instances.

• Step 5: Data Recovery (Recovery Site - As Needed)

* Restore critical file shares from backup systems.

* Verify data accessibility and integrity.

• Step 6: User Access & Connectivity (Recovery Site - 1 hour)

* Verify VPN access for remote users to the recovery site.

* Test internal and external access to recovered applications.

* Communicate access instructions to users.
