Backup NetScaler configuration
- You cannot use the backup file taken from one appliance to restore a different appliance.
- You can back up and restore appliances in an HA setup, but make sure that you restore to the same appliance from which the backup file was created. For example, if the backup was taken from the primary appliance of the HA pair, when restoring make sure that the appliance you are restoring is the same appliance, even if it is no longer the primary appliance.
- You cannot perform the backup and restore operation on a NetScaler cluster.
Manually
The command below will backup the nsconfig folder including:
- Current saved configuration
- Previous 5 saved configuration
- Licenses
- Certificates
- etc.

GUI
Connect to the NetScaler GUI, go to System then Backup and Restore.
Select Backup.
Enter the name and select Full or Basic, then press select Backup.
- Basic – this level would backup all the important configuration files along with the key log files and downloaded objects used in functional features like Application Firewall and Responder.
- Full – this level covers everything backed up using basic and adds other important files which are less frequently changed like SSL certificates/keys and license files.
The backup was successful.
