Data Backup Strategies: On-Prem, Cloud, and Hybrid
Data loss is not a question of if — it is a question of when. Hardware fails, people delete things, ransomware encrypts files, and disasters destroy offices. A backup strategy is your insurance policy against all of these.
The 3-2-1 rule
The gold standard for backup strategy is the 3-2-1 rule:
- 3 copies of your data
- 2 different storage media
- 1 copy off-site
This means your live data, a local backup, and an off-site backup. If any single copy is lost or corrupted, you still have two others.
On-premise backup
A local backup to a NAS or backup server in your office.
Pros: Fast backup and recovery, no internet dependency, full control Cons: Vulnerable to physical disasters (fire, flood, theft), requires hardware maintenance
On-premise backup is essential for fast recovery of large datasets. It should be your first line of defense.
Cloud backup
Backup to a cloud storage service (AWS S3, Azure Blob, Backblaze B2).
Pros: Off-site by definition, scalable, no hardware to maintain, protected from local disasters Cons: Slower recovery for large datasets, ongoing cost, dependent on internet connectivity
Cloud backup is your off-site copy. It protects against physical disasters and provides long-term retention.
Hybrid backup
The combination of on-premise and cloud backup. This is the recommended approach for most Jamaican businesses:
- Local backup for fast day-to-day recovery
- Cloud backup for disaster recovery and long-term retention
- Replication from local to cloud automatically
What to back up
- Servers — full image-level backups for bare-metal recovery
- Workstations — critical user data (documents, configurations)
- Databases — application-aware backups that ensure consistency
- Cloud services — Microsoft 365, Google Workspace data (it is your data, not theirs to protect)
- Network configurations — firewall, switch, and router configs
Testing
A backup that has never been tested is a backup that probably does not work. Test recovery:
- Monthly — restore a random file and verify it
- Quarterly — restore a full server to a test environment
- Annually — run a full disaster recovery simulation
