Don't back up the OS.

If you have a valid Service Contract, go to the Cisco website and download the IOS.

You don't have to concern about IOS backup. IOS image is stored on the flash and is decompressed and loaded from the scratch every time you restart your appliance. Running configuration is the only thing you should backup
