Backup + Disaster Recovery (DR) = African SME safety nets. 60% of SMEs without DR plan close within 6 months of major incident. Here's the modern 2026 strategy.
TL;DR
- 3-2-1 rule: 3 copies, 2 different supports, 1 offsite.
- RPO (Recovery Point Objective): how much data can be lost.
- RTO (Recovery Time Objective): how much time to restore.
- Tested restore: untested backup = no backup.
RTO / RPO per criticality
| Data type | RPO target | RTO target | Cost |
|---|---|---|---|
| Critical (transactions, payments) | <1 min | <1 hour | $$$$ |
| Important (user data, content) | <1 hour | <4 hours | $$$ |
| Standard (logs, analytics) | <24 hours | <24 hours | $$ |
| Cold (archives) | <7 days | <48 hours | $ |
3-2-1 backup strategy
- 3 copies:
- Live production (1)
- Local fast-restore backup (2)
- Different cloud offsite backup (3)
- 2 different supports:
- Cloud provider A (AWS S3)
- Cloud provider B (Backblaze B2 / DO Spaces)
- 1 offsite:
- Different geographical region
- Ideally different continent
MongoDB Atlas backup
Continuous backup (built-in)
- Snapshot every 6h
- Continuous oplog (RPO = 1 minute)
- Retention 7 days (Standard) to 5 years (custom)
- Point-in-time restore
Manual snapshot + offsite
`bash
# Atlas CLI
atlas backup snapshots create --clusterName myCluster
# Export to AWS S3 / DO Spaces
atlas backup exports create \
--clusterName myCluster \
--bucketName backup-bucket \
--iamRoleArn arn:aws:iam::xxx
`
Atlas backup cost
- M10 cluster : $57/mo
- + Continuous Backup: ~$30-100/mo (per volume)
- + Cross-region backup: +$20-50/mo
PostgreSQL backup (Render / Neon / RDS)
`bash
# Daily backup script
pg_dump --format=custom --compress=9 \
--file=/backup/db_$(date +%Y%m%d).dump \
postgresql://user:pass@host/dbname
# Upload S3
aws s3 cp /backup/db_*.dump s3://backups-bucket/postgres/
# Retention: delete >90 days
aws s3api list-objects --bucket backups-bucket \
--prefix postgres/ \
--query "Contents[?LastModified<='$(date -d '90 days ago' --iso-8601)'].[Key]" \
| xargs -I {} aws s3 rm s3://backups-bucket/{}
`
Better: use WAL-E / WAL-G for continuous archiving + point-in-time recovery.
User upload / file backup
DO Spaces / S3 versioning + cross-region replication:
`bash
# Versioning: keep all versions
aws s3api put-bucket-versioning \

`
Configuration + secrets backup
- Code : Git (already versioned)
- Secrets : 1Password / Doppler periodic exports
- Configs : Infrastructure as Code (Terraform / Pulumi in Git)
- DNS : Cloudflare zonefile exports
- SSL certs : Let's Encrypt auto-regen
Test restore — non-negotiable
Untested backup = no backup.
`bash
# Plan: quarterly
- Pick random backup from last week
- Restore to dedicated staging cluster
- Run smoke tests: login, create, read, delete
- Compare row counts vs prod (delta acceptable)
- Document time taken (measured RTO)
- Delete restored cluster
`
If restore fails / slow: improve backup strategy now, not in crisis.
Disaster Recovery Plan (DRP)
Written document, accessible offline:
`
- Emergency contacts (provider, team, legal)
- Up-to-date architecture diagrams
- Per-scenario runbook:
- DB corruption → restore PITR steps
- Data center outage → fail-over secondary
- Ransomware → isolate, restore clean backup
- Account compromise → revoke + rotate secrets
- Provider bankruptcy → migration plan
- RTO / RPO targets
- Communication plan (clients, employees, press)
- Compliance reporting (CDP / ICR / GDPR)
`
Test DRP 1x/year minimum (table-top exercise).
Common 2026 Africa scenarios
Scenario 1 — Ransomware
- Isolate infected systems
- Identify scope (which DBs/files affected)
- Restore from clean backup (offsite, immutable)
- Forensics: how attacker got in
- Patch + harden
- Resume operations
Scenario 2 — Silent DB corruption
- Detect via monitoring (data integrity checks)
- Identify corruption time
- PITR restore to just before
- Replay valid transactions from logs
- Resume
Scenario 3 — Atlas provider down
- Detect via uptime monitoring
- Check Atlas status page
- If <1h estimated: wait
- If >1h: activate DR cluster (other region)
- Switch DNS / connection strings
- Resume on DR cluster until fix
2026 SME backup cost
| Data volume | Stack | Monthly cost |
|---|---|---|
| 10 GB | Atlas backup + S3 | $30-50 |
| 100 GB | Atlas + cross-region + S3 | $80-150 |
| 1 TB | Atlas + cross-cloud | $200-500 |
| 10 TB | Enterprise multi-region | $1000-3000 |
ROI: backup = insurance. Breach cost 200K-2M €. Backup $50-500/mo.
Common mistakes
- No tested restore — discover invalid backup in crisis.
- Backups in same region as prod — single point of failure.
- No long-term retention — 7 days only.
- No offline backup (immutable) — ransomware encrypts backups too.
- No backup monitoring — silent fails.
- Plaintext secrets in backup — leak risk.
FAQ
Q: Encrypted backup?
A: Always. AES-256 server-side. Keys separate from backup.
Q: How long backup retention?
A: Compliance depends. 1-7 years per sector. SN data legal: 10 years.
Q: Backup automation tools?
A: Restic, BorgBackup (open source). Veeam (enterprise). Cloud-native (AWS Backup, GCP).
Conclusion
2026 Africa SME backup + DR: 3-2-1 + defined RTO/RPO + quarterly tested restore + written DRP. Cost $50-500/mo per scale. Clear ROI vs catastrophic incident. MongoDB Atlas + S3/DO Spaces + cross-region = sufficient modern stack.
