Backup & Resilience Strategy (BCP/DR) 💾

In today's reality, the question isn't whether your organization will experience data loss, but when. Backup isn't a product - it's your business's insurance policy.

The Gold Standard: The 3-2-1 Rule

This is the universal formula for data resilience:

  • 3 copies: of your critical data.
  • 2 different media: for example, a local server and an external disk or cloud.
  • 1 copy offsite: a geographically isolated backup to protect against physical disasters or ransomware.

🕑 Local Server Backup

Keeping full images of virtual servers. Enables instant file restore and resolves simple hardware failures within minutes.

🕑 Isolated Cloud Backup (Object Storage)

Sending data to the cloud with Immutability (cannot be altered). Even if an attacker breaches the local backup server and deletes everything - the cloud backup stays locked and cannot be deleted.

🕑 Replication

Real-time replication of servers to a secondary site. Unlike backup, replication is designed for DR (Disaster Recovery) and lets you run the business from the secondary site with almost no downtime.

🕑 Periodic Restore Testing

A backup that hasn't been tested doesn't exist. We perform periodic restoration tests to verify the data is intact and usable when it matters most.

🚨 The Big Myth: "We're in the cloud, Google and Microsoft back us up"

This is a critical mistake. The shared responsibility model of cloud providers is clear: they're responsible for availability, you're responsible for the data. Accidental deletion, a corrupted sync, or a disgruntled employee wiping SharePoint folders - none of that is covered by the provider. An external SaaS backup is essential.

📈 Resilience Metrics: RPO and RTO

When we design a backup procedure, we define two targets:

  • RPO (Recovery Point Objective): how much data are we willing to lose? (e.g., hourly backups.)
  • RTO (Recovery Time Objective): how long will it take to get back to full operation after a crash?
