Overview
Disaster Recovery Infrastructure ensures your critical systems and data survive site failures, outages, and disasters, and come back online within the time your business can tolerate. Nexus Compute designs and sources DR solutions, from replication to a secondary site to full failover, aligned to your continuity requirements. The design begins with an unglamorous exercise: listing your systems, deciding which of them the business genuinely cannot run without for a day, and being honest about the order they have to come back in. Almost every system depends on something else (authentication, DNS, a database, a license server), so a recovery plan that restores applications without their dependencies restores nothing usable. From that list come the two numbers everything else follows from: how much data you can afford to lose, which sets the replication method, and how quickly you need to be running, which sets whether the second site holds warm running capacity or cold hardware waiting to be built. Both cost money in proportion to how demanding they are, which is why we scope them per system rather than applying the strictest answer to everything.
Who This Solution Is For
Business Benefits
Business continuity
Critical systems keep running (or come back fast) through outages, site failures, and disasters.
Protects revenue and reputation
Minimizing downtime protects revenue, customer trust, and regulatory standing.
Meets continuity mandates
We design to the recovery objectives your industry and regulators require.
Tailored to your risk
From simple replication to full failover, we design DR proportionate to your risk and budget.
Typical Business Use Cases
Replication to a secondary site or colocation
Failover for critical applications and data
Regulatory business-continuity compliance
Resilience for mission-critical infrastructure
Mapping application dependencies into a workable recovery order
Standing up a warm secondary site for the systems that cannot wait
Industry Applications
Technical Overview
Disaster recovery solutions combining storage replication, secondary-site or colocation infrastructure, and failover orchestration, designed around your recovery-time and recovery-point objectives. We design the architecture and source the supporting infrastructure. The replication method follows the tolerance for data loss. Synchronous replication acknowledges a write only when both sites have it, which loses nothing but constrains how far apart the sites can be, because the distance between them becomes latency on every write. Asynchronous replication removes that constraint and accepts a defined amount of loss instead. The second site is the other half of the design: it can be your own premises, colocation, or a hybrid, and it has to be far enough away that the same event does not take both, while close enough for the replication method you have chosen. Then come the parts that are easy to overlook and decisive during a real event: how names and addresses move so clients follow the failover, whether the standby capacity is enough to run the workload rather than merely start it, where the licenses live, and how you fail back afterwards, which is frequently harder than failing over.

Frequently Asked Questions
What is the difference between backup and disaster recovery?
Backup is about recovering data; disaster recovery is about recovering the running business (systems, applications, and data) within a defined time. Backup is a component of DR. We design both as a coherent resilience strategy. Put another way: backup answers "can we get the data back", DR answers "can we serve customers on Monday". An organization can have flawless backups and still be down for a week because it has nowhere to run the restored systems.
Do we need a second site?
For meaningful DR, a geographically separate recovery location is important. This can be your own site, colocation, or hybrid. We advise on the most cost-effective approach for your risk profile. The distance is a genuine trade-off rather than a preference: far enough that one event cannot take both sites, close enough that the replication method you need still works, since synchronous replication becomes impractical beyond a certain separation.
How do we know it will work?
DR must be tested. We design for testability and advise on a regular DR test regime so recovery is proven, not assumed. A useful test fails over real workloads rather than reviewing the plan in a meeting, and it is scored against the recovery times you committed to. Most first tests reveal the same class of problem: a dependency nobody documented, a credential that lives only on the primary site, or standby capacity that starts the systems but cannot carry the load.
What does DR cost, and can we do it in stages?
It scales with how quickly you need to be back and how little data you can lose, so it is priced per system rather than as one figure. Staging it is normal and sensible: protect the handful of systems the business genuinely cannot run without first, prove the failover works for them, then extend coverage. That is a better use of the first budget than a comprehensive plan that has never been exercised.
How do users and applications actually reach the second site?
Through the parts of the design that are easy to leave until last: DNS and addressing, the network path into the recovery site, authentication, and any external dependency that points at your primary address. A failover that brings systems up which nothing can find has not recovered anything, so we design the client path with the same care as the data path, and we test it as part of the exercise.
How do we get back to the primary site afterwards?
Deliberately, and with a plan written before the event rather than during it. Failback means reversing replication, reconciling the changes made while you were running at the recovery site, and choosing a window to move back. It is frequently harder than the failover, because by then production data lives at the secondary site and the primary is stale. We design the return path as part of the architecture rather than treating it as the part that comes later.
