Freeze mode in NetBackup
In certain scenarios, you can enable freeze mode to prevent users from making changes to NetBackup for security reasons. In freeze mode, you cannot change NetBackup configurations and cannot use certain functionality based on the freeze mode options that are configured.
It is recommended that organizations identify scenarios (for example, malware attack) when they need to enable freeze mode, beforehand.
For more information, refer to the NetBackup Security and Encryption Guide.
