Preventive Measures: Implement system redundancy, load testing, and real-time monitoring. Contingency Planning: Create an incident response and disaster recovery plan, with clear communication protocols. Rapid Recovery: Use hot standby servers, automated scripts, and regular backups for quick recovery. Team Readiness: Train the team, define roles, and maintain on-call support. Communication: Keep clients and the team informed throughout the incident. Post-Incident Review: Conduct root cause analysis and performance reviews to prevent future issues.

Solid DR plans, document, test, and test more. Make sure critical system are redundant and have no single points of failure. Automation always helps, build scripts for quick failover.

The first thing that should be considered is monitoring the system performance in real time and will give some clue why the system fails. If the server fails the DR server should take the tasks automatically without interrupting the service. Active server,DR server should be backed up properly and taking snapshot can be additional protection for the server and smoothly recover the server.

I create a group with operation knowledge and development knowledge. Then you often arrive at the right solutions as the system manager has a good knowledge of the system and the developers can make changes and you quickly see the result.

The disaster recovery plan (DRP) must detail the restoration of critical services, including recovery times (RTO and RPO). Implement mirror servers and load balancing to ensure a seamless transition in case of failures. Use real-time monitoring tools with automatic alerts for a quick response. Conduct regular simulations to identify failures and evaluate your contingency plan. Maintain automatic backups in multiple locations. Document clear procedures and communicate them to your team. Provide ongoing training to ensure that everyone is familiar with the protocols. These actions ensure business continuity in the event of any failure.
