DRP or BCP? The two acronyms are often confused, yet they don’t refer to the same thing. One prevents the outage; the other organises the recovery. For an SME, understanding the difference — and knowing which one to put in place first — can be the line between a single disrupted day and several weeks of lost revenue. This 2026 guide explains the definitions, the RTO/RPO indicators, the 3-2-1 backup rule, and the method to build an operational plan suited to a small business or professional practice.
KEY FIGURE
60% of SMEs that suffer a major IT incident without a formal recovery plan close their doors within 6 months of the event (cybersecurity sector estimates, 2024-2025). The average cost of a ransomware attack on an Irish SME is now well into six figures, with the largest share tied to downtime — exactly what a properly sized DRP/BCP is designed to prevent.
DRP and BCP: two complementary plans, not synonyms
The BCP (Business Continuity Plan) and the DRP (Disaster Recovery Plan) are two complementary strategic frameworks, formally recognised in standards such as ISO 22301 and referenced by the Irish NCSC in its guidance for SMEs. They don’t share the same goal, scope or cost. Understanding this distinction is the first step before any investment.
BCP
Business Continuity Plan
The BCP covers the measures that allow the organisation to keep operating during an incident, with little or no noticeable interruption. It is anticipatory: fallback solutions are pre-built (secondary premises, ready-to-use remote work, redundant servers, dual internet links) so that the business never truly stops.
Goal: zero or minimal downtime.
Logic: redundancy and degraded operation.
Cost: high (duplicated infrastructure).
DRP
Disaster Recovery Plan
The DRP covers the procedures that allow the business to restart operations after an incident that has stopped them. It is reactive: an outage is accepted, but its duration and impact are tightly controlled through tested backups, restoration procedures and documented scenarios.
Goal: restart quickly without losing critical data.
Logic: backup, restore, procedure.
Cost: moderate, accessible to SMEs.
In practice, a well-equipped Dublin SME has a solid DRP (off-site backups, tested restore procedure, documented crisis scenarios) and BCP elements on the truly critical functions (for example: dual broadband, redundant email, ready-to-use remote workstations). A full BCP — meaning continuous 24/7 operation — is reserved for activities where one hour of downtime costs tens of thousands of euros.
DRP vs BCP: the difference at a glance
Here is the short, practical summary so the two are never confused again:
Question asked
BCP: “How do we avoid the outage?”
DRP: “How do we restart after the outage?”
Scope
BCP: the whole organisation (HR, premises, IT, suppliers).
DRP: focused on the information system.
Target delay
BCP: close to zero, transparent failover.
DRP: from a few hours to a few days, by design.
A useful analogy: the BCP is the twin-engine aircraft — if one engine fails, the second takes over and passengers don’t notice. The DRP is the diversion airport and the emergency landing procedure: the incident is accepted, but it has been rehearsed in advance so it ends well.
RTO and RPO: the two indicators that frame your plan
Before spending a single euro on a DRP or BCP, two questions must have a numerical answer. Those are the RTO and RPO indicators — the universal language of business continuity.
RTO
Recovery Time Objective
The maximum acceptable downtime — how long the business can run offline before the damage becomes unacceptable. An e-commerce site aims for minutes; an accounting practice in Dublin can usually tolerate a working day outside tax-filing peaks.
RPO
Recovery Point Objective
The maximum acceptable data loss — how much data you can afford to lose between the last good backup and the incident. With nightly backups your RPO is 24 hours; with continuous replication it can drop to a few minutes.
KEY POINT
The closer RTO and RPO get to zero, the more infrastructure cost explodes. A standard DRP for an SME (RTO 4-24 h, RPO 24 h) typically costs 5 to 15 times less than a real-time BCP (RTO < 1 h, RPO < 15 min). The golden rule: size these two values against the actual revenue-loss risk, never the other way around.
Three tiers to position your SME
- Standard tier — RTO 24 h, RPO 24 h. Daily off-site backups, documented restoration. Suitable for the majority of Irish SMEs and professional practices (accountants, retailers, tradespeople, small service businesses).
- Enhanced tier — RTO 4 h, RPO 1 h. Hourly incremental backups, pre-staged failover infrastructure. Suitable for SMEs with strong IT dependency (e-commerce, precision manufacturing, healthcare).
- Real-time tier — RTO < 1 h, RPO < 15 min. Synchronous replication, automatic failover, dual site. Suitable for businesses where each hour of downtime costs tens of thousands of euros.
The 3-2-1 rule: backup at the heart of every DRP
Every DRP rests on a reliable backup. Without a restorable backup, there is no recovery plan — only a hope. The 3-2-1 rule, recommended worldwide by backup vendors and security agencies, sets the minimum to follow:
3 copies
At least three copies of every critical dataset: the live original plus two backups. A single backup is never enough — if it is corrupted, you have nothing left.
2 media
On two different media: for example a local NAS plus cloud, or an external disk plus a managed backup service. Diversifying technology prevents a single failure from wiping out every copy.
1 off-site
One copy off-premises, ideally immutable and geographically distant. This is the part SMEs most often skip — and the very one that saves the business in the event of fire, theft, flood or ransomware.
The modern evolution: the 3-2-1-1-0 rule
Faced with the rise of ransomware, which now actively targets network-connected backups, the rule has been extended to 3-2-1-1-0:
- 1 additional copy that is immutable or offline (air-gap, S3 Object Lock, LTO tape removed from the safe) — impossible for an attacker to encrypt or delete.
- 0 errors during restoration tests. An untested backup is just a promise. Every serious DRP includes a quarterly restoration-test schedule.
Building your DRP/BCP: the 6-step method
A DRP/BCP is not a product you buy, it is a process you build. Here is the method we apply at Ezohiko on continuity engagements with SMEs and professional practices in Dublin and across Ireland.
- Map the critical business processes. List every essential activity (invoicing, production, customer relations, payroll…) and identify the IT resources that support it: applications, data, accesses, cloud dependencies.
- Run a Business Impact Analysis (BIA). For each critical process, quantify the cost of an outage of 1 hour, 4 hours, 24 hours, 1 week. That figure justifies the RTO and RPO chosen for each service.
- Identify disaster scenarios. Hardware failure, ransomware, fire, flood, loss of a cloud provider, prolonged broadband outage, sudden unavailability of a key person.
- Define technical solutions. 3-2-1-1-0 backup, redundant internet, standby servers, ready-to-use remote workstations, emergency administrator accounts, 24/7 support contracts where relevant.
- Document the procedures. An undocumented DRP does not exist. Each scenario needs its own runbook: who does what, in what order, with which passwords, which providers, which timing. Contact details must remain available outside the impacted information system.
- Test and maintain the plan. Restoration test at least quarterly, full crisis exercise at least once a year, update at every major change to the IT system or business processes.
How much does a DRP/BCP cost an Irish SME?
The cost of a DRP/BCP depends on the RTO/RPO target, the data volume and the number of critical applications. Below are the orders of magnitude observed in 2026 for a typical Irish SME (10 to 50 staff, single site, around ten applications):
Standard DRP
Setup: €3,000 to €8,000
Monthly: €100 to €400
Includes: 3-2-1 backup, immutable cloud copy, documented procedure, annual test.
Enhanced DRP
Setup: €8,000 to €25,000
Monthly: €400 to €1,200
Includes: hourly backups, standby infrastructure, quarterly tests, monitoring.
Real-time BCP
Setup: €25,000 to €80,000+
Monthly: €1,500 to €5,000+
Includes: dual site, synchronous replication, automatic failover, 24/7 on-call.
For the vast majority of SMEs, a well-sized standard DRP is enough to turn a major incident into a few-hour event, and acts as an insurance whose ROI is immediate the first time it prevents a costly outage.
DRP as a Service by Ezohiko: 4-hour recovery, without enterprise-level investment
Building a DRP in-house ties up time, niche skills and a budget that an SME rarely has on hand. That is why Ezohiko offers PRA as a Service: a packaged offer, sized for SMEs and professional practices, that turns business continuity into a monthly service — with no standby hardware to buy, no secondary server to manage, no complexity.
THE OFFER IN ONE LINE
Your server goes down tonight. Monday morning — when do you open? With Ezohiko’s PRA as a Service: guaranteed recovery in 4 hours, tests twice a year, data hosted at OVH in the EU.
Guaranteed 4-hour recovery
Contractual RTO of 4 hours. Your critical servers restart on our standby infrastructure, your team gets their tools back in half a day rather than several weeks.
Tested twice a year
An untested DRP is just a promise. We run two real failover exercises every year, hand you the report, and fix any gaps before a real incident exposes them.
EU-hosted data (OVH)
Your backups stay on European datacenters (OVH), GDPR-compliant. No transfer outside the EU, no foreign jurisdiction, no regulatory bad surprises.
The PRA as a Service offer includes 3-2-1-1-0 backup, pre-staged failover infrastructure, a documented procedure, two annual tests, and oversight by a time-share IT manager who knows your environment. The whole thing is delivered as a monthly subscription, sized to your RTO/RPO and critical-data volume — accessible to organisations from 5 to 100 staff. For a typical SME, the service falls within the “Standard DRP” to “Enhanced DRP” cost ranges shown earlier, with no upfront hardware investment.
CASE IN POINT
“We had a primary server failure on a Friday evening. Thanks to the DRP we had built with Ezohiko, we restarted on the standby infrastructure in under 4 hours, with no data loss beyond the previous hour. By Monday morning the team was working normally. Without that plan we would have lost a week.” — Director, accounting practice, 15 staff.

Frequently asked questions about DRP and BCP
What is the essential difference between DRP and BCP?
A BCP (Business Continuity Plan) aims to keep the business running during an incident, with little or no noticeable interruption, through redundancy and fallback solutions. A DRP (Disaster Recovery Plan) aims to restart the business after an incident that has stopped it, while controlling downtime and data loss. The BCP is anticipatory and continuous; the DRP is reactive and time-bounded. The BCP covers the whole organisation; the DRP focuses on the information system.
Does an SME need a DRP or a BCP?
Every SME should have at least a formal DRP, meaning a documented backup-and-restore framework. A full BCP — full continuity, no interruption — only makes sense for the truly critical functions: doubling internet links, making email redundant, hosting the most critical application on a dual-site service. For most Irish SMEs and professional practices, a properly built DRP (RTO 4-24 h, 3-2-1-1-0 backups, tested procedure) covers the bulk of the risk at an accessible cost.
What do RTO and RPO mean in practice?
The RTO (Recovery Time Objective) is the maximum acceptable downtime: how long the business can stay offline before the damage becomes serious. The RPO (Recovery Point Objective) is the maximum acceptable data loss: if the last good backup is from last night and the incident happens at 5pm, the actual RPO is around 17 hours. The lower these two values, the more expensive the required infrastructure. Quantifying them correctly is the prerequisite step before any investment decision.
Is the 3-2-1 rule still valid against ransomware?
Yes, but it has evolved into 3-2-1-1-0. Modern ransomware actively targets network-reachable backups to prevent any restoration. The extended rule adds two requirements: one immutable or offline copy (air-gap, object storage with write-lock, physical LTO tape) that an attacker cannot encrypt, and zero errors during restoration tests, because an untested backup protects no one. An SME that follows 3-2-1-1-0 will recover its data even after a successful ransomware attack.
How often should a DRP be tested?
A partial restoration test at least every quarter, and a full crisis exercise at least once a year. The restoration test verifies that backups are actually usable (the failure rate on a first test, in an unaccompanied SME, frequently exceeds 30%). The crisis exercise verifies that procedures, contacts, passwords and documented timings still match the current state of the IT system. Without these two rituals, a DRP silently degrades and reveals its gaps at the worst possible moment.
