Most site owners think about disaster recovery only in abstract terms. Fires, floods, server crashes, hosting provider failures. The events seem distant. The planning gets postponed indefinitely.
Then something happens. A data center has a major outage. A hosting company goes out of business. A natural disaster affects the region where your servers live. The site goes down. The data is at risk. The business is interrupted.
Sites with disaster recovery plans get back online in hours. Sites without them might never come back at all. This piece covers what disaster recovery actually involves, how to plan for it, and how to execute when disaster strikes.
What Disaster Recovery Means
The concept covers more than just backups.
Beyond Backups
Backups are part of disaster recovery but not the whole thing. A backup is data. Disaster recovery is the process of getting from “everything is broken” to “everything is working again.”
The process involves backups, infrastructure, procedures, and people. Each piece matters.
Different From Day-to-Day Issues
Day-to-day issues (a broken plugin, a temporary outage, a minor data loss) are handled through routine maintenance. Disaster recovery addresses bigger events. Total data center loss. Catastrophic data corruption. Major incidents that disrupt operations significantly.
The Recovery Objectives
Two metrics define disaster recovery requirements:
Recovery Time Objective (RTO) is how long until the site is back online.
Recovery Point Objective (RPO) is how much data loss is acceptable.
For some sites, an RTO of a few hours and RPO of a day is fine. For others, both need to be measured in minutes.
The objectives drive the disaster recovery approach.
Common Disaster Scenarios
Planning starts with knowing what could happen.
Hosting Provider Failure
Your host has a major outage. Could be hours. Could be days. In rare cases, hosts go out of business entirely with little warning.
Data Center Disasters
Fire, flood, power failure, network failure at the data center. Affects all sites hosted there.
Hardware Failures
Specific servers fail. Disks die. Memory corrupts. Most modern hosting has redundancy, but failures still happen.
Software Failures
A bad update breaks the site. A database corruption makes data inaccessible. A failed migration leaves you in a broken state.
Human Error
Accidental deletion of important data. Misconfiguration that takes down the site. Mistakes happen.
Natural Disasters
Earthquakes, hurricanes, wildfires affecting the region where your servers live.
Cyber Attacks
Ransomware that encrypts your data. Destructive attacks that delete data. The previous pieces in this series covered these.
Account Issues
Billing problems that suspend your hosting. Disputed ownership of the domain. Locked-out account.
Building a Disaster Recovery Plan
The plan addresses what happens for each scenario.
Identify Critical Assets
What does the business need to operate? The website itself. The customer database. Email. Payment processing. Inventory management.
Each critical asset needs disaster recovery consideration.
Set Recovery Objectives
For each asset, what RTO and RPO does the business need? Some assets can tolerate longer outages and data loss. Others cannot.
Be realistic. Setting an RTO of zero (no downtime) is expensive. Set objectives based on actual business needs.
Document Current State
What runs where? Which hosting provider? Which services? Where is the data stored?
Without this documentation, recovery is harder because you have to remember everything during a crisis.
Plan Recovery Steps
For each scenario, write down the steps. Where backups live. How to restore them. What credentials are needed. Who to contact.
The plan should be detailed enough that someone other than you could execute it if needed.
Test the Plan
Plans that have not been tested often do not work. Annual disaster recovery tests reveal gaps before they matter.
The test does not have to be a real restore. Tabletop exercises (walking through what would happen) catch most issues.
Backup Strategy for Disaster Recovery
Backups are the foundation of recovery.
What to Back Up
Site files (themes, plugins, uploads, custom code).
Database (everything stored in the database).
Configuration files (wp-config.php, .htaccess, server configs).
Email data if your host handles email.
DNS configuration if you manage it directly.
SSL certificates and keys.
Where to Store Backups
Backups on the same server as the site are not real backups. If the server dies, the backups go with it.
Off-site storage is essential. Different geographic location is better than same-location off-site storage.
Cloud storage services (Amazon S3, Google Cloud Storage, Backblaze B2, Wasabi) are common destinations for off-site backups.
How Many Copies
The 3-2-1 rule is a good baseline. Three copies of data. Two different storage types. One off-site.
For example: live site, on-server backup, off-site cloud backup. Three copies, two types (server disk and cloud), one off-site.
How Often
Daily backups are the minimum for most active sites. More frequent backups (hourly, continuous) for sites with significant data changes.
E-commerce sites with high transaction volume often need continuous backup or close to it.
How Long to Keep
Recent backups for fast recovery. Older backups in case issues are not noticed immediately.
A common pattern: daily backups for 30 days, weekly backups for 90 days, monthly backups for a year or more.
Tested Restores
Backups that have never been tested might not work. Quarterly restore tests confirm the backup system actually works.
The test reveals whether backups are complete, whether restoration works, and how long it takes.
Beyond Backups: Recovery Infrastructure
For faster recovery, infrastructure matters too.
Multiple Hosting Providers
Sites with the highest availability needs use multiple hosting providers. If one fails, the other takes over.
This is expensive and complex. Most sites do not need it. But for business-critical sites, it can be worth the investment.
DNS Failover
If you have a backup server (at a different provider), DNS failover can automatically switch traffic to it when the primary fails.
Services like AWS Route 53, Cloudflare, and DNSimple offer DNS failover.
CDN Caching
CDNs cache content at edge locations. If the origin server goes down, the CDN can continue serving cached content for some time.
This is a partial mitigation rather than a real DR solution, but it can keep static content available during outages.
Staging Environment
A staging environment that mirrors production can serve as a quick recovery option in some scenarios.
If production breaks, staging can sometimes be promoted to production temporarily.
Documentation of Infrastructure
Knowing exactly how the site is configured is essential for recovery. Server settings, application configuration, integrations.
The documentation lives separately from the site itself. Otherwise you lose it when the site goes down.
Execution During a Disaster
When disaster strikes, response matters.
Acknowledge the Situation
Confirm what has happened. Verify the scope. Is the entire site down? Specific functionality? Is data lost?
The acknowledgment focuses the response.
Activate the Plan
Pull out the disaster recovery plan. Start following the steps. The plan exists for this moment.
Communicate
Customers want to know what is happening. Employees need to know what to do. Partners may need information.
Honest communication during disasters builds more trust than silence. Even partial information is better than nothing.
Execute Recovery
Follow the recovery steps. Restore from backups. Rebuild infrastructure if needed. Verify functionality.
For complex recoveries, the work might take many hours. Be patient and thorough.
Verify Completely
After restoration, verify everything works. Test critical functionality. Check data integrity. Confirm all systems are back.
A partial restoration that misses something is worse than knowing it is not fully restored yet.
Resume Normal Operations
Once verified, communicate that operations are restored. Resume normal business. Schedule the post-disaster review.
After the Disaster
The work continues after immediate recovery.
Post-Disaster Review
Within days of resolution, review what happened. What caused the disaster. How well the recovery went. What could have been better.
The review drives improvements.
Update the Plan
The plan probably needs updates based on the experience. Steps that did not work. Information that was missing. Improvements identified.
Implement Prevention
Some disasters can be prevented or made less impactful. Identify what would help.
Document for Stakeholders
Insurance claims, regulatory requirements, customer communications may need documentation of what happened.
Common Disaster Recovery Mistakes
People stumble in predictable ways.
Not Having a Plan
The biggest mistake. Sites without DR plans recover slowly or sometimes not at all.
Inadequate Backups
Backups that are not off-site. Backups that have never been tested. Backups missing critical data. Each of these makes recovery harder or impossible.
Untested Plans
Plans written in theory rarely survive contact with reality. Testing reveals gaps.
Overly Complex Plans
Plans that are hard to follow get ignored during crises. Complexity is the enemy of execution.
Outdated Plans
Plans that have not been updated do not reflect current systems. They cause confusion during use.
Single Points of Failure
Recovery that depends on one person, one service, one location. Disasters can affect any of these. Redundancy in the plan matters.
Ignoring DNS
DNS is often forgotten in DR planning. But DNS controls everything else. Without proper DNS handling, recovery is much harder.
Closing Thoughts on Recovering from Catastrophe
Disaster recovery is one of those topics that gets attention only after a disaster. Sites that plan in advance recover better than sites that improvise during crises.
For most sites, the right approach is proportional to the stakes. A small hobby site needs basic backups and a simple recovery plan. A business-critical site needs comprehensive DR with tested procedures.
The investment in DR planning is real. Time to write the plan. Cost of off-site backups. Effort to test periodically. But the cost is small compared to the cost of catastrophic failure without preparation.
Sites that have experienced disasters and recovered well usually had plans. Sites that have experienced disasters and not recovered usually did not. The pattern is consistent enough to take seriously.
If your site does not have a disaster recovery plan, this is one of the more important business continuity investments available. The work is bounded. The protection is real. The peace of mind of knowing you can recover from worst-case scenarios is genuine.
For sites that already have plans, periodic review and testing keeps them effective. The plan that worked five years ago may not work today because so much has changed. The discipline of maintaining the plan over time is what produces reliable recovery when needed. Sites that take disaster recovery seriously stay in business through events that put unprepared sites out of business. The decision to invest in DR is the decision to be in business after the disaster. Make the plan. Keep it current. Hope you never need it. If you do, you will be grateful.
