9 Costly DRaaS Mistakes to Avoid

Avoid These 9 Common Disaster Recovery as a Service Mistakes

Mistake 1: Confusing Backup with Full Disaster Recovery

Many organisations confuse data backups with full disaster recovery. Backups, whether file-level or server-level, create one or more copies of your data. Whereas a full disaster recovery ensures rapid failover and application restoration.

If your business relies solely on backups, you risk extended downtime and the loss of transactional data. Always ensure your DRaaS can recover the complete IT infrastructure, including servers, applications, and networking.

Mistake 2: Failing to Define Clear RTO and RPO Targets

Recovery Time Objective (RTO) and Recovery Point Objective (RPO) are key metrics that define how quickly your systems will be restored and how much data loss is acceptable.

Without defining clear RTO and RPO targets, you risk unwanted downtime that exceeds your business’ tolerance levels. As a result, your customers may experience service disruptions, leading to financial losses and damage to your brand’s reputation.

Map the RTO and RPO for each system, and ensure your DRaaS provider consistently meets these targets.

Mistake 3: Not Testing Your DRaaS Plan Regularly

Your DRaaS plan may look perfect on paper, but without testing and verification, it may fail when real disasters strike.

Ideally, testing for disaster recovery issues should include:

• Full end-to-end disaster simulations
• Scheduled failover drills
• Partial system recovery exercises

In addition to regular testing, ensure you document each test, identify room for improvement, and update your plan to support reliable disaster recovery when you need it the most. Without testing, you’re leading your business into a false sense of security.

Mistake 4: Overlooking Compliance and Data Residency Requirements

UK businesses need to comply with the strict requirements set out by the GDPR and the UK Data Protection Act for data handling, storage, and processing. Non-compliance can mean penalties and fines, damage to brand reputation, and potential loss of customer trust. 

Choose a DRaaS provider who takes compliance standards seriously by clearly defining data location, encryption protocols, and audit capabilities.

Mistake 5: Ignoring Application-Level Recovery Dependencies

Modern applications depend on interconnected services such as databases, APIs, and third-party integrations. Recovering only one component can break functionality or corrupt data.

DRaaS best practices include identifying all your dependencies and verifying with your DRaaS provider that they can recover the entire application, not just the server.

Mistake 6: Choosing a Provider Without Clear SLA Guarantees

By defining SLAs, you define quantifiable expectations for uptime, recovery time, and support availability. Unclear or missing SLAs leave you with no recourse if a provider fails during an incident.

Always clearly define and document enforceable SLAs that outline response times and penalties for disaster recovery issues and missed commitments. 

Mistake 7: Underestimating Bandwidth and Replication Needs

DRaaS relies on data replication between primary and secondary sites that requires steady bandwidth. Insufficient bandwidth can slow replication, delay recovery, and potentially increase data loss. 

You also need to consider the volume of data being replicated and the optimisation techniques used.

Mistake 8: Failing to Integrate DRaaS into a Wider Business Continuity Plan

A DRaaS plan is integral to a business continuity strategy, but it is only one aspect of it. You’ll benefit from integrating DRaaS into a wider plan that accounts for crisis management procedures, alternative work locations and network access.

The success of a DRaaS plan also depends on coordination across IT, operations, and leadership teams.

Mistake 9: Treating DRaaS as a Set-and-Forget Solution

This is another common mistake in disaster recovery as a service that businesses make. Setting it once and neglecting it risks breaking replication during system and application updates, overlooking compliance requirements, and missing security patches.

You need to regularly audit, review, and update your DRaaS to keep your disaster recovery plan effective.
