Everyone mentioned that installing Rancid is one way. :)

Another is to let the router do it for you.  Put something like this in 
your config, so that any time you save the config or once a day, it'll 
drop a copy on your Linux box's TFTP server:

archive
  path tftp://192.168.1.2/router-confg.txt    ! can be ftp, rcp, scp, sftp also
  write-memory
  time-period 1440

Another way to tftp the config, if you have net-snmp in your Linux distro:
(Yeah, it's a depricated MIB... the newer MIB does ftp, rcp etc but needs 
a a few more lines of shell scripting or Perl to pull it off...)

snmpset -v 1 192.168.1.1 routerwritecomm .1.3.6.1.4.1.9.2.1.55.192.168.1.2 s router-confg.txt

or even this (yuck!):

curl -u user:pass http://192.168.1.1/level/15/exec/-/show/startup-config/CR > router-confg.txt
