Restore by backup file does not work correctly in NetScaler.
Resolution
After restoring the NetScaler using the backup file, restart the device without saving the configuration. Issuing 'save config' before rebooting will overwrite the restored "ns. conf" with the currently running configuration.
So, to restore NetScaler with a backup file, the procedures should be as below:
Upload the backup file.
Restore with the backup file.
Reboot without saving configuration.
Note: If a dialog box appears asking if want to “save the config”, select “No, do not save”. please test in the environment first.
Problem Cause
After restoring with a backup file, only the "ns. conf" file and other setting files on the disk are restored. The running-config would not be restored immediately.
If run "save config" before rebooting the appliance, the running configuration is saved in the "ns. conf" file. As a result, the contents of the restored "ns. conf" file will be overwritten.
