In Disaster Recovery scenarios, the Restore service is responsible for restoring data from backups to bring the system back to its operational state. Backup creates the copies, Recovery is the broader process of full system restoration, and Configuration manages settings, but only Restore specifically handles the data restoration aspect.
In disaster recovery (DR), 'restore' specifically refers to the process of retrieving and reinstating data from a backup to bring a system back to a working state. Backup is the act of creating the copy, and recovery is the broader overall process of returning systems to operation, so 'restore' is the term tied directly to bringing data back.
