Creating a USB backup

You may create a clone backup while a station is running or stopped. When the controller is powered on, the software continuously monitors the USB port. Putting a USB flash drive in the port triggers backup/restore mode.
Prerequisites:
  • USB backups are enabled on the controller:
    Platform Administration > Advanced Options > USB Backup Enabled property is selected
     
    NOTE: USB backup supports only FAT32 and FAT32X file systems. NTFS is not supported.
     
  • You need a USB flash drive with enough memory to contain the complete platform and station image along with the operating system and all software modules.
     
    CAUTION: Only flash drives (USB sticks ≤128GB) are recommended for backup/restore operations. USB bus powered external hard drives often have higher power requirements and so may not function as expected, possibly resulting in permanent damage to the drive or to the JACE-8000. Plugging in an external hard drive may cause the controller to become unresponsive, requiring a reboot.
     

Perform the following steps:
  1. Confirm that the controller’s power is on.
  2. Insert a USB flash drive into the USB port.
    The backup and restore LED turns on.

    4 Shutdown (initiates an orderly shutdown)
    5 Backup and restore LED
  3. Hold the backup and restore button until the LED flashes at medium speed (100mS on and 100mS off), then release the button.
    The system begins the backup. While backing up, the LED flashes slowly (one second on, one second off).

    When the backup completes, the system prepares the USB flash drive to be removed safely.

     
    NOTE: If the backup is unable to complete successfully, the LED flashes rapidly (200ms on, 200ms off, 200ms on, 3s off), indicating an error. In this case, simply unplug the USB thumb drive, wait for the LED to turn off, then insert the thumb drive and try the backup procedure again. If problems persist, possible causes could be:
    • Insufficient disk space on the thumb drive
    • Write protect enabled on the thumb driver

     
  4. When the backup and restore LED turns off, remove the USB flash drive and store it in a safe place.

The backup image includes the contents of the boot partition, /home/ Niagara, /opt/ Niagara, etc. The name of the resulting image file follows this convention: hostid (unique host ID of the JACE-8000), underscore (_) timestamp, For example:

  • Qnx-TITAN-D01C-CA36–CB10–4E3B_20170912230355
  • Qnx-TITAN-D01C-CA36–CB10–4E3B_20171015212346
