Disaster Recovery and Business Continuity Planning for Custom Software

Meerako — A Dallas-based technology partner building genuine resilience into custom software, not just hoping nothing goes wrong.

Most businesses running custom software have some vague notion of "we have backups" as their disaster recovery plan — which is genuinely inadequate, and the inadequacy typically only becomes apparent during an actual incident, exactly the worst possible time to discover it. Real disaster recovery and business continuity planning requires deliberate, tested preparation well before anything goes wrong, covering scenarios well beyond "the database has a backup somewhere."

• Why "we have backups" isn't actually a disaster recovery plan.
• The key metrics — RTO and RPO — that should drive real planning.
• What genuine disaster recovery testing actually requires.
• How to scope disaster recovery investment appropriately to your real risk.

A backup existing somewhere doesn't answer the actual operational questions that matter during a real incident: how quickly can the system actually be restored from that backup, how much data (if any) would be lost in the gap between the last backup and the incident, and — critically — has this restoration process actually been tested recently, or is it an assumption that's never been verified under real conditions. An untested backup restoration process is a genuine, common source of disaster recovery failures precisely when they matter most.

Recovery Time Objective (RTO) — how long can the business tolerate the system being down before the impact becomes genuinely unacceptable. Recovery Point Objective (RPO) — how much data loss (measured in time — an hour of transactions, a day's worth) is genuinely tolerable in a worst-case scenario. These aren't abstract technical metrics — they're business decisions that should be made deliberately by business stakeholders, then used to drive the specific technical architecture (backup frequency, redundancy investment) that actually achieves them.

A disaster recovery plan that's never been tested is, practically speaking, unverified and should be treated with real skepticism about whether it would actually work under pressure. Genuine testing means actually executing a restoration — in a test environment, on a defined schedule — and measuring whether the real RTO and RPO achieved match what the plan assumes, not just confirming that backup files exist somewhere in storage.

Not every system needs the same level of disaster recovery investment — a genuinely business-critical system where extended downtime would be catastrophic justifies real investment in redundancy, fast failover, and tight RPO; a lower-stakes internal tool with a higher tolerance for downtime doesn't need the same level of investment. Scoping this deliberately, system by system, based on real business impact avoids both under-investing in genuinely critical systems and over-investing in systems where it isn't justified.

Genuine business continuity planning extends beyond the technical disaster recovery plan itself — clear internal communication protocols during an incident, defined roles and responsibilities for who does what during a recovery event, and a plan for how the business operates (even in a degraded, manual way) while technical systems are being restored. A technically sound disaster recovery plan without this broader operational planning still leaves real gaps during an actual incident.

We help clients establish genuine RTO and RPO targets based on real business impact, architect the specific technical redundancy needed to achieve them, and build in actual, scheduled testing — not a plan that exists only on paper and has never been verified to actually work.

How often should disaster recovery restoration actually be tested? At minimum annually for most business-critical systems, though more frequent testing (quarterly) is warranted for genuinely critical systems where an untested plan carries real, severe risk if it fails when actually needed.

Does cloud hosting automatically provide adequate disaster recovery? No — cloud providers offer infrastructure and tools that can support genuine disaster recovery, but the actual RTO/RPO achieved depends entirely on how your specific architecture uses those tools, not an automatic guarantee from the platform alone.

What's a realistic cost range for implementing genuine disaster recovery for a business-critical system? Highly dependent on the specific RTO/RPO targets and system complexity — tighter targets (near-zero downtime, minimal data loss tolerance) cost meaningfully more to achieve than more relaxed targets, which is exactly why setting these targets deliberately based on real business impact matters.

Should disaster recovery planning cover scenarios beyond technical system failure, like natural disasters or cyberattacks? Yes — genuine business continuity planning should cover the range of realistic scenarios that could disrupt operations, including cyberattacks and ransomware specifically, which have become an increasingly common and serious disaster recovery scenario in recent years.

Genuine disaster recovery and business continuity planning requires deliberate RTO/RPO targets driven by real business impact, technical architecture built to achieve them, and actual, scheduled testing — not an untested assumption that backups alone constitute a real plan.
