Backup Is Not Disaster Recovery

A backup is a copy; recovery is a capability

Having backup files does not prove that the business can restore critical systems within an acceptable timeframe. Disaster recovery includes the people, procedures, credentials, dependencies and infrastructure required to turn those copies back into working services.

Two questions matter: RPO and RTO

The Recovery Point Objective defines how much recent data the business can afford to lose. The Recovery Time Objective defines how long the business can tolerate the service being unavailable. Backup frequency and recovery architecture should be designed around those requirements.

Common failure patterns

Typical weaknesses include backups stored only beside the production system, credentials shared with the production environment, no immutable or offline copy, no monitoring of failed jobs and no documented restore procedure.

Test restores, not just backup jobs

A green “backup successful” status only confirms that a job completed. Periodic restore testing verifies that the data is usable, the process is understood and dependencies have not been missed.

Design for business continuity

The correct solution may combine local recovery speed with offsite resilience. The important point is to identify what must be restored first, who is authorised to do it, and what infrastructure is required if the primary site or equipment is unavailable.
