定时自动备份【脚本】

建立执行脚本

vi /home/Network_Config_Backup/start.sh

#!/bin/bash
#使用该脚本前需要安装tftp,xinetd,expect
#取时间戳
BACKUP_DATA=`date +%Y%m%d`
#创建时间戳的备份目录
mkdir -p /home/Network_Config_Backup/$BACKUP_DATA

#TFTP服务根目录授权
chmod 777 /home/Network_Config_Backup/$BACKUP_DATA

log=/data/log/start_${BACKUP_DATA}.log
#修改TFTP根目录
sed -i "s/Network_Config_Backup\/......../Network_Config_Backup\/$BACKUP_DATA/" /etc/xinetd.d/tftp

echo          Cisco使用tftp方式将配置文件上传到服务器 
echo          Huawei、H3C使用窗口记录方式获取配置信息

chmod 777 /home/Network_Config_Backup/start.sh
新建user.passwd存放设备信息

vi /home/Network_Config_Backup/user.passwd
*设备名品牌 IP地址用户名密码*

user.passwd()格式
Huawei-TEST-SW01 Huawei 192.168.1.55 admin admin12345 Cisco-TEST-SW01 Cisco 192.168.1.66 admin admin12345

cd /home/Network_Config_Backup

sh start.sh //执行脚本即可自动备份

修改tftp文件储存位置

vi /etc/xinetd.d/tftp 
service tftp
{     socket_type            = dgram
      protocol               = udp
      wait                   = yes
      user                   = root
      server                 = /usr/sbin/in.tftpd
      server_args            = -s /data2/SW -c
      disable                = no
      per_source             = 11
      cps                    = 100 2
      flags                  = IPv4
}
