Backup vs Disaster Recovery: The Difference That Matters

Two numbers define your position

Recovery Point Objective is how much data you can afford to lose, measured in time. If backups run nightly, your RPO is up to 24 hours.

Recovery Time Objective is how long the business can operate without the system. It includes sourcing hardware, rebuilding the operating system, restoring data, and verifying the result — not just the restore itself.

Both numbers are business decisions, not technical ones. IT implements them; leadership sets them.

What a complete position looks like

Backups exist in multiple copies, at least one offsite and at least one immutable. Restores are tested on a schedule and the duration is recorded. A written runbook names which systems come back first, where they are restored, and who authorizes the decision.

Without the runbook, recovery depends on whoever is available and how well they remember.

The most common failure

Backup software reports success while writing to a destination that has been full, disconnected, or excluded for months. Nobody notices, because nobody restores.

Verification is not an optional extra. It is the only thing that turns a backup into a protection.
