Recovery operations are the hands-on work of resuming critical activities after a disruption. Where strategy sets the targets, operations carry them out: restoring systems and data, handing services back to their owners, and validating that what has been recovered is actually working and safe to use.

Within the Recovery phase, operations turn plans into restored service. This is where a recovery strategy meets reality, and where sequence and verification matter most. Bringing systems back in the wrong order, or returning them before they are clean, can extend an outage or reintroduce the very problem that caused it. Careful operations avoid both.

In practice, recovery operations restore from trusted backups or standby systems, rebuild affected hosts, and reconnect dependencies in a planned order driven by criticality. Before a system returns to production, teams validate it: confirming data integrity, checking that it is free of adversary presence, and verifying that it performs as expected. Handover transfers responsibility back to business and operations owners with clear communication about state and any residual limitations. Throughout, actions are documented so the organization has an accurate record of what was restored and how.
