4 Ways to Improve IT Infrastructure Resilience and Disaster Recovery

During the full-scale war in Ukraine, we had to rapidly implement multiple contingency measures to maintain our IT infrastructure resilience. We secured backup power through generators, established redundant connectivity via Starlink and mobile internet, and implemented role shadowing across our teams. Looking back, our role shadowing initiative made the biggest difference to our preparedness, as it ensured project continuity even when team members became temporarily unavailable during crisis situations.

Based on my experience conducting cyber security maturity assessments, implementing comprehensive backup systems with regular restoration testing has been the most impactful change for improving infrastructure resilience. We established a rigorous schedule for data backups across all critical systems, but the real difference came from implementing quarterly restoration drills that validated our recovery capabilities. This approach significantly reduced our potential downtime during incidents and provided our leadership team with confidence that we could maintain business continuity through various disruption scenarios.

Improving our "infrastructure resilience" isn't about computer hardware. Our disaster is a hurricane or a flood, and the single change that made the biggest difference to our preparedness was moving all critical job documents to a shared, secure digital folder immediately after they were signed.

The challenge was simple: if a hurricane hit, we risked losing every signed contract, insurance claim, and material receipt stored in our physical office. Our process was to stop storing anything critical on paper. Every signed contract, every client photo, and every payment record is scanned and uploaded instantly.

This completely transformed our preparedness. The single change means the entire company can access all quotes, contracts, and payment schedules from a cell phone, even if the office is under water or without power. Our operation can continue running because the vital information is secure and accessible from anywhere.

The key lesson is that preparedness is about secure, instant access to information. My advice is to stop seeing digital file storage as a luxury. Start seeing it as a mandatory disaster recovery system for your entire business's survival, because paper and local files will not survive a major storm.

The single biggest impact was moving critical systems to a redundant cloud server with automatic backups. Before, our disaster recovery hinged on our physical servers that required manual intervention. Now, we have snapshot backups every 15 minutes on the cloud. Recovery is measured in minutes instead of hours.
