Business Continuity & Backup Guide
Resilience Strategy for Modern Threats
Backups are your last line of defence against ransomware, theft, and human error. A backup strategy is not about "saving files"; it is about "recovering business operations" fast enough to survive.
1. The 3-2-1 Rule (The Non-Negotiable Standard)
Any strategy less than this is a gamble, not a backup.
3 Copies of DataYour live data (Copy 1), a local backup for speed (Copy 2), and a cloud backup for disaster (Copy 3).
2 Different Media TypesDon't store backups on the same server as the data. If the power supply kills the server, it kills the backup too. Use NAS + Cloud.
1 Copy Offsite (Immutable)This is critical for ransomware protection. Immutable storage means "Write Once, Read Many". Even if a hacker gets your admin password, they scientifically cannot delete the immutable backup until the timer expires.
2. The "Shared Responsibility" Gap
There is a dangerous myth that "Microsoft backs up my emails". They don't.
- Microsoft ensures the infrastructure works (Uptime).
- You are responsible for the data (Retention).
SaaS Backup SolutionYou MUST use a third-party tool (e.g., SkyKick, Datto, Veeam) to backup Exchange Online, SharePoint, and OneDrive. Microsoft's native recycle bin is temporary (30 days) and does not protect against malicious permanent deletion.
3. Testing: The Only Proof
A backup is Schrödinger's Cat: it both works and doesn't work until you observe it.
Quarterly Fire DrillPick a random folder. Delete it. Try to restore it. Measure how long it took. If it took 4 hours, can the business afford to be down for 4 hours?
Image-Based VerificationFor servers, can you spin up the backup as a virtual machine in the cloud? (Instant Boot). This allows you to work off the backup while the main server is being fixed.
