Perform this procedure to back up and restore the contents of the internal compact flash to a USB flash device without entering multiple copy commands. This procedure is useful if you want to copy the complete compact flash contents to another chassis.
Caution
Always use the usb-stop command to safely unplug the USB drive from the USB slot.
Important
Disable logging using the command: no boot config logging.
You must have a USB storage device ready to use that is at least 2 GB. The switch supports USB 1 and 2.
The system verifies that the USB flash device has enough available space to perform the backup operation. If the USB flash device does not have enough available space, the system displays an error message.

The backup action can take up to 10 minutes.
