It's just fail2ban doing its job...
run 'service iptables stop' to kill it off(temporarily), or unjail the offending IP using fail2ban client command line:
fail2ban-client set $jail unbanip $ip
Replace $jail with the respective jail your IP is locked in and $ip with your IP.
To prevent fail2ban from starting backup on reboot 'chkconfig fail2ban off'
... I will say though, doing this will expose your server to brute force techniques.
