Points to note:

• Before you restore the SDX appliance using the backup file of a different SDX appliance, add the Management Service network settings according to the settings available in the backup file.
• Ensure that the platform variant on which the backup was taken is the same as on which you are trying to restore. Restoring the backup file between two different platform variants is not supported.
• Citrix recommends restoring SDX backup only after the network configuration is set. You can specify the following network settings for the SVM:
  • SVM IP address
  • Hypervisor IP address
  • Subnet mask
  • Gateway

Restore the NetScaler instance

You can restore the NetScaler instance in the SDX appliance to the NetScaler instances that are available in the backup file.

Point to note:A VPX instance fails to restore if:

• The instance does not have a management NIC assigned to it, and
• The instance is managed from the SDX Management Service only through LACP. The restore fails because SDX Management Service cannot restore the channel configurations automatically. To avoid this issue, manually restore the channel configuration to complete the VPX instance restore.

To restore the NetScaler instance in the backup file:

1. On the配置tab, in the navigation pane, expandManagement Service, and then clickBackup Files.
2. In theBackup Filespane, select the backup file and then clickRestore.
3. In theRestoredialog box, selectInstance Restore.
4. Select the NetScaler instances that you want to restore and then clickProceed.
5. (Optional) If the backup file is encrypted, when prompted, type the password and then clickOK.

Note

Ensure that an appropriate XVA, build image, and channel configuration are present on the SDX appliance that runs the instance that is being restored.
