The following scripts which I run on linux will backup the configurations of CatOS and IOS based switches to the tftp server on the linux host using SNMP.
1) The CatOS version
#!/bin/bash
# This script uses SNMP to download the configuration of the CatOS
# switches, via tftp to the /tftpboot directory
#
# This version (see also saveconfig) operates based on
# the CISCO-STACK-MIB and applies to modules running the Catalyst
# Operating System (OS)
#
# Gavin Newman
#
# The production version of this script exists in the /home/root
# directory and is run via a cron job or as required

2) The IOS version
#!/bin/bash

# and applies to modules running the Cisco IOS Release 12.0 or later
# software.

# directory and is run via a cron job or as required
