That's the worst possible time to learn your backups weren't tested or nobody knows who's supposed to call the insurance company.
This guide covers what a data center disaster recovery plan actually includes, the RTO and RPO metrics that should drive your decisions, and practical steps for Chicagoland businesses to build a plan that holds up under pressure. Done right, a DRP minimizes downtime, protects your data, and keeps you on the right side of compliance requirements.
Key Takeaways
- Document a disaster recovery plan (DRP) as the step-by-step path to restore IT systems after an outage
- Set RTO and RPO first — they define how fast and how completely you must recover
- DRP is a focused subset of business continuity planning (BCP), not a replacement for it
- Untested plans create false confidence — regular testing is non-negotiable
- Managed IT providers can simplify backup, failover, and recovery validation
What Is a Data Center Disaster Recovery Plan?
A data center disaster recovery plan is a documented, step-by-step strategy for restoring IT infrastructure, data, and connectivity after a disruptive event. It spells out specific procedures, assigned owners, and defined recovery targets so teams know exactly what to do when systems go down.
Common causes of data center disasters include:
- Natural disasters — storms, flooding, extended power grid failures
- Power outages — still the leading cause of impactful outages according to the Uptime Institute's 2025 Annual Outage Analysis
- Hardware failure — aging servers, failed drives, network equipment breakdowns
- Cyberattacks and ransomware — increasingly common and often the most disruptive
- Human error — nearly 40% of organizations reported a major outage from human error in the past three years, per the same Uptime research
Without a DRP, businesses face extended downtime, permanent data loss, compliance violations, and reputational fallout. Datto's SMB survey found average downtime costs for small and mid-sized businesses climbed from $46,800 to $274,200 over just two years.
Data Center Disaster Recovery Plan Checklist: What to Include
A strong DRP starts with knowing what matters most: your critical systems, data, and the risks that threaten them.
Inventory and Risk Assessment
Begin with a complete inventory of critical systems, applications, and data, ranked by business impact. Not every system deserves the same level of protection. Your email server and customer database probably need faster recovery than archived project files.
From there, run a risk assessment specific to your organization:
- Weather and natural disasters (severe storms, floods, hurricanes)
- Cyberattack likelihood based on your industry and data sensitivity
- Hardware age and failure risk
- Connectivity dependencies and single points of failure
RTOs, RPOs, and Recovery Sites
Define recovery time objectives (RTO) and recovery point objectives (RPO) for each system tier. These numbers guide everything downstream: how often you back up, where you store copies, and how much you invest in failover infrastructure.
This is also where you establish your backup and failover approach: cloud-based disaster-recovery-as-a-service (DRaaS), a secondary data center, or off-site backups. LME Services helps small and mid-sized businesses design backup and disaster recovery strategies with restorability as the goal, not just backup completion, across Office 365, Google Workspace, and server environments.
Roles, Communication, and Testing
Finally, assign clear roles and responsibilities. Someone needs to own the failover decision. Someone needs to talk to customers and vendors if systems go down. Build a crisis communication plan before you need it, not during the outage.
Document your response procedures in plain language, then test them. A plan nobody has practiced is a plan that will fall apart under real pressure.
Understanding RTO and RPO
These two metrics are the backbone of any DRP, and they answer different questions.
Recovery Time Objective (RTO) is the maximum acceptable time to restore a system after disruption. A law firm might need its case management system back within 4 hours; a retail business's point-of-sale system might tolerate a slightly longer window.
Recovery Point Objective (RPO) is the maximum acceptable amount of data loss, measured in time. An RPO of 15 minutes means you can't afford to lose more than 15 minutes of transaction data, which dictates how frequently you need to back up.
Both targets should vary by system criticality:
| System Tier | Example RTO | Example RPO |
|---|---|---|
| Mission-critical | Minutes | Seconds to minutes |
| Business-important | Under 4 hours | 1-4 hours |
| Standard | 4-24 hours | 12-24 hours |
These figures are illustrative, not universal standards. Your actual targets should reflect your specific operations.
One common mistake is setting aggressive RTO/RPO targets without the backup infrastructure to hit them. A 15-minute RPO is meaningless if you only back up nightly.
How Data Backup Supports Disaster Recovery
Backup strategy is where DRPs succeed or fail in practice. The Cybersecurity and Infrastructure Security Agency (CISA) recommends the 3-2-1 rule as a foundation: three copies of your data, on two different media types, with one copy stored off-site.
This isn't just theory. CISA specifically recommends combining on-site and remote backups to address different threat types. A fire destroys on-site copies, while a remote copy survives.
Common backup types include:
- On-site backups — fast to restore, but vulnerable to local disasters
- Off-site backups — physically separate, protecting against site-level loss
- Cloud backups — scalable and geographically distant, ideal for RPO targets under an hour
Backup frequency should match your RPO. If your RPO is 4 hours, nightly backups won't cut it.
Here's the part businesses skip: testing restores, not just confirming backups completed. A backup job that "succeeded" isn't the same as a file you can actually recover.
LME's Hansen & Cleary case study found a law firm whose previous backups weren't monitored or tested at all. Required emails simply couldn't be located when needed. That's a preventable failure with periodic test restores.
Best Practices and How Often to Update Your DRP
These practices keep your disaster recovery plan usable when an outage hits:
- Automate backups so recovery doesn't depend on someone remembering a manual job
- Maintain redundant infrastructure where budget allows
- Use geographically diverse recovery sites so one regional event can't take out primary and backup together
- Monitor systems continuously so failures get caught before they cascade
How often you review the plan matters as much as what you put in it. NIST guidance recommends reviewing and testing your DRP at least annually, and right after major infrastructure, staffing, or business changes. Don't wait for the annual review if you've just migrated to a new server environment or onboarded a new department.
Build testing into that cadence:
- Full-scale DR tests at least once a year
- Tabletop exercises more often (walk the plan on paper without failing systems over) at far lower cost
DRP vs. BCP: Understanding the Difference
These terms get used interchangeably, and that's a mistake.
A disaster recovery plan (DRP) focuses narrowly on restoring IT systems and data. A business continuity plan (BCP) addresses how the entire business keeps functioning during any disruption, not just an IT one.
BCP covers areas outside pure IT recovery, including:
- HR and workforce continuity
- Day-to-day operations and customer service
- Physical facilities and stakeholder communications
Think of DRP as nested inside BCP. Your IT recovery plan supports the broader goal of keeping the business running, but it's not the whole picture. A business can have a flawless DRP and still fail if employees can't reach the office. The same gap appears when there's no plan for communicating with customers during an extended outage.
Both should be developed together. Treating IT recovery as an afterthought to business continuity, or vice versa, leaves gaps.
Frequently Asked Questions
What should be included in a data center disaster recovery plan?
A system inventory ranked by business impact, a risk assessment, defined RTO/RPO targets, backup and failover strategy, assigned roles, a communication plan, and documented, regularly tested procedures.
What are the 5 steps of disaster recovery?
Assess your downtime tolerance, inventory critical systems, define RTO/RPO targets, build the documented response plan, then test it regularly under realistic conditions.
What are RTO and RPO, with examples?
RTO is how fast you need systems restored: for example, 4 hours for a law firm's case files. RPO is how much data loss is acceptable: for example, no more than 15 minutes of transaction data.
How does data backup work for disaster recovery?
Backups create restorable copies of your data stored on-site and off-site, refreshed on a schedule that matches your RPO targets. The copies only matter if they've been tested for actual restorability.
How often should a DRP be updated?
At least annually, and immediately after significant changes to your systems, staffing, or business operations.
What is the difference between a DRP and a BCP?
A DRP is IT-focused recovery. A BCP covers organization-wide continuity across every department. The DRP typically sits inside the broader BCP.
