The VPN Concentrator has two locations for storing image files: the
active location, which stores the image currently running on the system;
and the backup location. Updating the image overwrites the stored image
file in the backup location and makes it the active location for the
next reboot. Updating twice, therefore, overwrites the image file in the
active location; and the current image file is lost. The Manager
displays a warning on this screen if you have already updated the image
without rebooting.
So, it actually doesn't make a copy, it just flags an active location
for next reboot. But in case you have updated the IOS and then want to
revert back to the previous one (which is now presently in the backup
location), then take the following step:
1. Attach a console to the VPN Concentrator.
2. Reboot or power cycle the concentrator.
3. After the "Boot configured XXXMb of RAM" message, look for three dots
and then press Ctrl-G (^G).
4. Select option 5 - Toggle active image from the Boot Menu Options.
5. Select option 1 - Continue to load main code.
