🛡️ 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?
- Snapshots: Full image of the server (Easy, expensive).
- Dumps: SQL export of just the data (Efficient, portable).
- Offsite: Pushing encrypted backups to S3/Wasabi (Crucial for ransomware protection).
💡 Executive FAQ
- Q: Is RAID a backup?
- A: NO. RAID protects against Hardware Failure (disk crash). It does not protect against Human Error (deleting a file) or Malware. You need offline snapshots.
- Q: How often should we test backups?
- A: A backup that hasn't been tested (restored) is just a hope. Test quarterly.
