Using native IOS on Catalyst 45xx switches, is there a way to perform an automatic backup of the configuration to a TFTP server every 24 hrs? Right now, it is done manually with the write net command to our TFTP server (10.1.1.1). When I go into global config, the command archive is not available. I also checked to see if the IOS could be upgraded, but most of the 45xx only goes to 12.2. Thanks in advance.
