Disaster Recovery and Business Continuity

What is physical disaster recovery?

Physical disaster recovery is the work of making sure recovery hardware exists, is installed and can be powered on where your plan says it will be. Disaster recovery planning typically focuses on replication software, RPO and RTO targets and runbook automation, and all of that is your IT team’s domain. But every recovery scenario ultimately depends on physical infrastructure being available, powered, cabled and racked at the recovery site. That physical dimension is often the weakest link in an otherwise well-designed recovery strategy, because it is rarely tested end to end. DataTech Logistics covers that layer: site build-outs, equipment staging, transport, installation, cabling, labeling and hardware replacement after an incident. We do not run recovery software, restore data or perform the failover. A sound plan, like the one Ready.gov’s business continuity guidance describes, names an owner for each of those pieces, and we are the owner of the hardware logistics.

What is the difference between a hot, warm and cold site?

The difference is how much hardware is already installed when you declare a disaster. A hot site has production-equivalent equipment racked, cabled and powered, so little physical work remains. A warm site has power, network and some equipment in place, and the rest is delivered and installed at activation. A cold site has space, power and cooling but no IT equipment, so everything must be shipped, racked and cabled. Hotter sites recover faster and cost more to keep standing. We support cold, warm and hot standby models across compute, storage and network tiers. See hot and warm site implementation and our guide to hot, warm and cold site recovery targets.

Site type	Hardware in place	Physical work at activation	Standing cost
Hot site	Racked, cabled, powered	Minimal: physical checks and any replacements	Highest
Warm site	Power, network, partial equipment	Deliver, rack and cable remaining gear	Moderate
Cold site	Space, power and cooling only	Ship, rack, cable and power on everything	Lowest

How do you build out a disaster recovery site?

You build a DR site the same way you build production, before you need it. Our DR site buildout and hardware pre-staging service installs, cables, labels and powers on standby equipment at your secondary or tertiary locations, so it is ready for activation on demand. Each build is documented with rack elevations, port maps and photos, so your IT team can configure and maintain the systems with an accurate record of what is where. Location matters as much as the build. A recovery site in the same flood zone or on the same power grid as production shares its risks, so check candidate sites against the FEMA Flood Map Service Center and our guide to selecting a disaster recovery site location. For organizations with contractual recovery agreements with colocation providers, we handle equipment delivery, installation and cabling within committed recovery timeframes. See DR site build-out and equipment staging.

What happens physically when disaster strikes?

When an actual disaster occurs, the physical job is to get working hardware in place faster than the outage costs you. Our rapid-response teams can mobilize to deploy replacement infrastructure, recover salvageable equipment, or stand up temporary environments at alternate facilities within hours of activation. That can mean pulling pre-staged spares from storage, receiving replacement hardware from your OEM, transporting it under chain-of-custody documentation, then racking, cabling and powering it on at the recovery site. Salvage work covers de-installing and moving equipment out of a damaged room before conditions get worse. What we do not do is the failover itself: bringing systems and data up at the recovery site, restoring from copies and redirecting users is your IT team’s work, and we schedule around it. For hardware that has failed or been destroyed, see emergency equipment replacement, available around the clock.

How should DR tests cover the physical layer?

A DR test should prove that the hardware is where the plan says and that people can reach it, not just that the software fails over. We provide the physical execution layer for tabletop and live failover exercises: hardware sweeps that check serial numbers, physical condition, rack positions, labels and link lights against the record; staging and delivering equipment for the test; and returning the site to standby afterwards. Firmware levels, recovery software and data checks are your IT team’s part of the test. NIST SP 800-34, the federal contingency planning guide, treats testing, training and exercises as a core part of any plan, and physical gaps are among the findings tests most often surface: a missing cable, a dead PDU, a rack nobody can access after hours. See DR testing logistics support and our article on realistic disaster recovery testing.

How does physical logistics affect your recovery time?

Physical logistics sets a floor under your recovery time that no software can lower. If recovery depends on hardware that is not yet at the recovery site, your real recovery time includes procurement or retrieval, transport, installation, cabling and power-on, plus the time needed to get crews and access approvals to the facility. Supply chain lead times for servers, network gear and storage can stretch well beyond a recovery target, which is why critical spares are often bought ahead and pre-staged. Distance, building access, freight elevator availability and after-hours site rules all add time. A credible recovery time objective is built from those physical steps, measured in rehearsal, not assumed. Our guide to recovery time objectives and physical logistics walks through how to measure each step. Pre-staging, hotter site models and tested transport plans are the main ways to shorten it.
