Abstract: Disaster recovery (DR) planning for hybrid infrastructures that combine Solaris and Linux poses unique challenges due to differences in tooling, system architecture, and operational practices. Solaris often supports legacy, mission-critical applications, while Linux drives modern, scalable workloads. This document provides a comprehensive guide to building a resilient DR strategy across both platforms. Key areas include risk assessment, backup and recovery tooling, system state preservation, and application/database restoration. Emphasis is placed on automation through Ansible, shell, and Python scripts, as well as configuration management and monitoring integration. The guide also highlights best practices such as maintaining consistent time and user IDs, isolating recovery zones, and leveraging enterprise backup solutions. Through clear documentation, defined team roles, and routine testing, organizations can achieve a DR framework that is platform-aware, repeatable, and aligned with evolving operational and compliance requirements.
