The additional Veeam capabilities that must be included in the conceptual design for gold level systems are SureBackup and Secure Restore. SureBackup is a feature that allows you to automatically verify the recoverability of your backups by running them in an isolated virtual lab. This can help you meet the requirement of testing the gold tier backups to verify recoverability. Secure Restore is a feature that allows you to scan your backups for malware before restoring them to the production environment. This can help you meet the requirement of scanning all backups for malware before restoring.
