You can use CISCO-CONFIG-COPY-MIB to copy startup or running
configuration to a tftp server or ftp/rcp in new releases.

You also might want to take a look at Rancid.  It pulls the configs into
a CVS tree and can show you differences between each revision history.
It doesn't send out alarms AFAIK, but you should not be stuck in a
position where you have no backup config.
