A backup creates a recoverable copy of information. Disaster recovery defines how critical services will return after disruption. Both matter: a company may have copies of its files and still be unable to resume an application quickly if the infrastructure, identities or network it depends on are unavailable.
Identify which systems must be recovered first and what the business can tolerate. Recovery point objective (RPO) describes acceptable data loss measured in time. Recovery time objective (RTO) describes the target time for restoring service.
Define protected data, backup frequency, retention, storage locations, access controls and independent copies. A storage array or cloud synchronization alone may not provide the recovery protection needed for every scenario.
Applications may depend on databases, directory services, licensing, network access and external integrations. A recovery plan should account for these dependencies rather than treating each server as isolated.
Restore a representative set of data or applications under controlled conditions. Verify that the information is usable and that recovery procedures meet the agreed objectives. A successful backup notification does not prove recovery readiness.
Agree who declares an incident, who has access to recovery systems, how staff will communicate and how normal operations will resume. Update the plan when systems or business priorities change.
If your organization already has backups but no tested recovery process, start by reviewing your critical applications, current backup schedules and acceptable downtime.
