🛡️ RISK BADGE: 🚑 DISASTER RECOVERY
Executive Summary: What is it?
A Backup Strategy is the protocol for copying and archiving data so it can be restored in case of data loss (hack, corruption, or accidental deletion). The "3-2-1 Rule" is the industry standard: 3 copies of data, on 2 different media, with 1 offsite.
CFO / Business Impact: What does it cost/risk?
Existential Risk. 60% of small businesses that lose their data shut down within 6 months. In Docker self-hosting, YOU are the backup provider. There is no "Undo" button unless you built it.
Technical Reality: How does it work?
- Full Snapshots: Capturing a complete image of the server. Easy to restore but more expensive to store.
- Database Dumps: Exporting specific SQL data. Highly efficient and portable across different environments.
- Offsite Storage: Pushing encrypted backups to a remote, air-gapped provider to protect against ransomware.
💡 Executive FAQ
- Question: Is RAID a backup?
- Answer: No. RAID protects against hardware failure (disk crashes) but does not protect against human error or malware.
- Question: How often should we test backups?
- Answer: A backup that hasn't been successfully restored is only a hope. Test your restoration protocol quarterly.
