Definition

Backup and recovery is the practice of copying and protecting data and systems so they can be restored after loss, corruption, or disruption. It is a core resilience control that supports business continuity and reduces the impact of incidents like ransomware, accidental deletion, hardware failure, and natural disasters.

Examples

  • A company restores a database from last night’s backup after a failed update corrupts records.
  • After a ransomware incident, an organization rebuilds systems and recovers files from offline backups.

Security is not only about preventing attacks. It is also about being able to recover when something goes wrong. Backups are one of the most practical and powerful controls because they give you a way back from data loss. If your only copy of important data is the live system, then a single mistake, failure, or attack can become a major outage.

Backups matter for everyday incidents like accidental deletion, and they matter for worst-case incidents like ransomware. In both cases, recovery quality depends on how well backups are designed, protected, and tested.

Remember: A backup that has never been tested is a hope, not a plan. Recovery is the proof that backups work.
