NetBackup and NetBackup Appliances Hardening Guide

Configuring immutability using GUI

You can configure immutability using the Access Appliance GUI.

To configure immutability using GUI

  1. Go to Settings > Security management > Immutability. Click Edit.
  2. Choose any of the lockdown modes under Mode Selection. You can choose from Normal, Enterprise and Compliance. The supported features for each mode are listed.
  3. If you choose Enterprise or Compliance mode, you also have to configure the retention time range from which the appliance administrators will be allowed to select when creating backup images.

    These values will also be used as default values while provisioning storage for different use-cases (such as NFS) from GUI.

    Specify the maximum and minimum retention time. These modes also lock down the system and disable immutable data destruction operations. Click Save.

    Note:

    Ensure that the image retention period in backup policies is within the lockdown mode retention time to avoid any error during backup.
