Why Every SMB Needs an IT Disaster Recovery Plan
A server crashing on Friday evening. A ransomware attack encrypting your client databases. A fire in your server room. These scenarios aren't reserved for large corporations — 82% of SMBs that suffer a major outage without a disaster recovery plan close within 24 months.
An IT disaster recovery plan (DRP) for your SMB isn't a luxury. It's operational insurance that defines precisely how your business restarts after a disaster.
The 2 Fundamental Metrics of Your DRP
Before any implementation, define two key indicators:
- RPO (Recovery Point Objective): how much data can you afford to lose? 1 hour? 24 hours?
- RTO (Recovery Time Objective): how quickly must you be operational again? 4 hours? 1 day?
| SMB Profile | Recommended RPO | Recommended RTO |
|---|---|---|
| E-commerce | < 1 hour | < 2 hours |
| Accounting firm | < 4 hours | < 8 hours |
| Manufacturing SMB | < 24 hours | < 24 hours |
Action step: gather your department heads and ask — "How long can you work without access to system X?" Their answers determine your RPO/RTO targets.
The 5 Pillars of a Solid IT Disaster Recovery Plan for SMBs
1. Critical Asset Mapping
List everything that keeps your business running:
- Servers (physical and virtual)
- Databases (PostgreSQL on Supabase, MySQL, etc.)
- Business applications (ERP, CRM, invoicing software)
- Cloud services (Vercel, OVHcloud, AWS)
- Network access and VPNs
Use a structured spreadsheet or a tool like Notion to keep this map up to date.
2. The 3-2-1 Backup Strategy
The golden rule:
- 3 copies of your data
- 2 different media types (local server + cloud)
- 1 offsite copy (remote datacenter)
# Example: automated PostgreSQL backup to S3
pg_dump -h localhost -U admin my_database | gzip > /tmp/backup_$(date +%Y%m%d).sql.gz
aws s3 cp /tmp/backup_$(date +%Y%m%d).sql.gz s3://my-drp-bucket/backups/
To automate without coding, build an n8n or Make workflow that triggers your backups and notifies you via Slack or email on failure.
3. Failover Infrastructure
For SMBs, the cloud dramatically simplifies failover:
- OVHcloud Public Cloud: preconfigured standby instances you spin up during an incident
- Vercel for web applications — the global CDN provides built-in availability
- Supabase with PostgreSQL replication enabled across regions
Realistic budget: a "cold" standby environment (shut down, manually activated) costs between €50 and €200/month for a typical SMB.
4. Detection and Alert Automation
An untested DRP is a useless DRP. Set up:
- UptimeRobot or Better Uptime to monitor your services (free up to 50 monitors)
- An n8n workflow that verifies your daily backup status
- PagerDuty or Slack alerts to immediately mobilize your technical team
# Simplified n8n check example
Trigger: Cron - every day at 7am
Step 1: HTTP Request → verify today's S3 backup exists
Step 2: IF backup missing → send Slack alert
Step 3: IF backup present → log success to Supabase
5. Documentation and Restart Procedures
Your DRP must be a living document, not a forgotten PDF on a NAS. It should contain:
- The exact restart sequence (which service to restore first)
- Credentials and access stored in a manager like Bitwarden or 1Password
- Emergency contacts: hosting provider, IT partner (like Otomy), telecom operator
- Each person's role during a crisis
Use Claude AI to generate a first draft of your procedure from your asset map, then have your technical team validate it.
Testing: The Step 90% of SMBs Skip
An untested DRP is an unkept promise. Schedule:
- Quarterly restoration test: actually restore a backup to a test environment
- Biannual failover test: simulate an outage and activate your standby infrastructure
- Annual review: update the asset map, contacts, and procedures
Success metric: time your actual recovery and compare it to your RTO target. If the gap exceeds 30%, adjust.
How Much Does a DRP Cost for an SMB?
Contrary to popular belief, an IT disaster recovery plan for SMBs doesn't require an enterprise budget:
| Component | Estimated Monthly Cost |
|---|---|
| Cloud backup (S3/OVH) | €20 – €80 |
| Monitoring (UptimeRobot Pro) | €7 |
| Cold standby infrastructure | €50 – €200 |
| Automation (self-hosted n8n) | €0 (hosted on existing VPS) |
| Expert support (Otomy) | Custom quote |
Total: between €80 and €300/month for complete peace of mind.
Where to Start Today
- Identify your 3 most critical systems — the ones without which you can't invoice
- Verify you have at least one working offsite backup
- Test a restoration this week — not next month
- Document the procedure, even in 10 lines
- Contact a specialist like Otomy to audit your resilience and build a DRP tailored to your budget
The question isn't if an outage will happen, but when. And when it does, the only thing separating your SMB from those that close is a tested and maintained disaster recovery plan.
