Disaster recovery planning often includes cloud backups, data replication across locations, and the ability to restore systems from snapshots within minutes. Yet the entire plan can fall apart if both your primary and backup systems are in the same building and a single power feed fails. Effective disaster recovery planning needs a physical strategy just as much as a data strategy. That means redundant power, diverse fiber routes, cooling, and controlled access to hardware. Let’s look at where disaster recovery plans fail most often.
On paper, everything looks under control. An RTO of four hours. An RPO of fifteen minutes. Applications grouped into three priority tiers. Recovery tests every six months. Yet even the best disaster recovery planning depends on one critical assumption: that the backup infrastructure will actually be available when it’s needed. And that’s the assumption companies test the least.
Key Takeaways
- Effective disaster recovery planning requires both a physical and data strategy to avoid failure during outages.
- Many companies focus on RTO and RPO but often overlook physical infrastructure and its availability during a disaster.
- True backup infrastructure needs physical separation, including different power grids and fiber routes, to ensure resilience.
- Colocation in TIER III-certified data centers can provide better connectivity and redundancy than in-house server rooms.
- Disaster recovery planning must become a business priority, integrating physical infrastructure considerations into operational resilience discussions.

Paper plans vs. physical reality
RTO and RPO measure recovery time and data loss. They don’t tell you whether your backup environment has power, cooling, or network connectivity when disaster strikes. That’s why many companies can recover their data but still fail to restore their operations.
The difference only becomes clear during a real incident. Secondary systems may be located just two floors below the primary ones, connected to the same power feed and the same network provider. A fire at a substation, a fiber cut during roadworks, or a cooling failure can bring both environments down at the same time. In that situation, disaster recovery planning has nowhere to fail over. The redundancy exists on paper, not in the physical infrastructure.
Physical location determines whether disaster recovery planning actually works
True backup infrastructure needs physical separation. A different power grid. A different flood zone. A different fiber route. An in-house server room rarely meets those requirements, and building a second facility for an event that may happen once a decade makes little financial sense for most companies.
Data center colocation solves that problem without the upfront capital investment. A TIER III-certified data center provider with N+1 redundancy and a 99.982% availability SLA delivers a level of resilience that’s difficult to achieve in an in-house server room. Around 60% of Czech internet traffic passes through the country’s largest commercial data centers, providing a level of network connectivity that a single corporate connection simply can’t match.
Choosing the right data center provider matters just as much. A carrier-neutral provider doesn’t lock you into a single network operator or compete with you through its own cloud services. Your backup environment remains yours.
Power, cooling, and connectivity: where downtime really begins
According to the Uptime Institute’s 2026 outage analysis, power failures remain the leading cause of major outages. UPS systems, transfer switches, and generators are the most common points of failure. Connectivity issues are also becoming more frequent, and fiber-related outages tend to last longer than most others.
The financial impact is just as significant. According to the same report, 57% of organizations said their most recent major outage cost more than USD 100,000, while one in five reported losses exceeding USD 1 million.
None of these issues can be solved with better backup software. Compare what your disaster recovery plan typically covers and what it overlooks:
| Data Layer | Physical Infrastructure Layer |
| Backup frequency and RPO | Independent power feed and generator |
| Backup encryption and integrity checks | N+1 redundant cooling |
| Automatic application failover | Dual fiber routes from different carriers |

Make disaster recovery planning a business priority
Recovery targets on paper hold up only until the first real test. Test the entire recovery process, not just individual components. Fail over to your backup site. Have your technicians physically access the hardware. Measure how long it takes before your business is selling, invoicing, and serving customers again.
Regulations are moving in the same direction. Both NIS2 and DORA require organizations to demonstrate operational resilience, including physical infrastructure and documented access logs, not just the existence of backup copies. That’s why decisions about your backup infrastructure belong in boardroom discussions alongside insurance and business continuity, not at the bottom of the IT team’s task list.
One question reveals everything
Ask your IT team one simple question: Where exactly does the secondary fiber route to your backup site run? If the answer is hesitant, your disaster recovery planning probably exists only in a shared document. The next outage will be the first to find out.
