A single hard drive failure can destroy years of work. The 3-2-1 strategy can save you from going under.

## What is the 3-2-1 strategy?

- **3** copies of your data (the original plus 2 copies)
- **2** different types of media (local plus cloud)
- **1** copy off site (a remote location)

## Why backups fail

1. **They are never tested** (40% of cases)
2. **Copies sit in the same physical place** (30%)
3. **There is only one backup** (20%)
4. **Backups are stale or corrupt** (10%)

## Backup types by company size

### Small company (1–10 employees)
- Google Drive/OneDrive for documents
- Automatic weekly backup to an external drive
- Monthly copy stored off site
- Cost: €50–100/month

### Medium company (11–50 employees)
- NAS in the office with RAID
- Daily backup to the cloud
- Backup server at a second location
- Cost: €200–500/month

### Large company (50+ employees)
- An enterprise backup system
- Real-time replication
- A secondary data centre
- Cost: €1,000–5,000/month

## Backup frequency by data type

### Critical (hourly)
- Customer database
- Invoicing systems
- Configuration files

### Important (daily)
- Working documents
- Corporate email
- Source code

### Normal (weekly)
- Media files
- Archived documents
- System logs

## Recommended tools

## Disaster recovery plan

### RTO (Recovery Time Objective)
- Critical: 1–4 hours
- Important: 4–24 hours
- Normal: 24–72 hours

### RPO (Recovery Point Objective)
- Critical: 15 minutes
- Important: 1 hour
- Normal: 24 hours

### Recovery procedure

1. **Assess the incident** (15 min)
2. **Activate the plan** (30 min)
3. **Recover critical systems** (1–4 hours)
4. **Verify integrity** (1–2 hours)
5. **Resume operations** (varies)

### Recovery testing

**Monthly:** restore random files
**Quarterly:** a full recovery drill
**Annually:** a complete disaster recovery test

### Legal compliance

- **GDPR**: backing up personal data is mandatory
- **SOX**: 7-year retention for financial data
- **HIPAA**: encrypted backup for medical data

- The backup lives in the same building
- Restoring takes you more than 4 hours
- The process is not documented anywhere
- The team does not know how to recover data
