随着网络设备的增多，通过人手备份网络设备倍感压力，而且效率低。有编程基础的人可能会通过Python的parimiko 或者netmiko 连接到设备操作 把文件通过ftp 上传到FTP服务器, 在通过定时任务,定期自动备份。这个应该是现阶段主流非人民币网络玩家的最优解决方案。
今天我们来看看oxidized这个被称之为“最好用的”网络备份系统，友好的支持不同厂商。
oxidized简介
oxidized 是一个网络设备备份系统, 轻量级,可扩展,支持超过90多个操作系统。个人觉得它无与伦比的优势, 同时支持h3c,华为,思科。
随着容器化的兴起，部署软件变得的越来越简单，有的已经帮您封装好，你开箱即用就可以了。好了下面，我们看看这个oxidized系统有没有镜像的。

把官方的 oxidized/oxidized 镜像拉下来
[root@node1 ~]# docker pull oxidized/oxidized:latest
下载完启动镜像
[root@node1 data]# docker run --name='oxidized' -itd -v /data/oxidized:/root/.config/oxidized -p 8888:8888/tcp -t oxidized/oxidized
4bbb01b608e38c59469b1056e24c65f1f36f6e65b0734ab1e86b64b4efcf3306
说明一下：挂载本地/data/oxidized目录到容器内的/root/.config/oxidized目录下，将本地8888端口映射到容器的tcp8888端口。
查看是否已经启动完
[root@node1 data]# docker logs oxidized *** Running /etc/my_init.d/00_regen_ssh_host_keys.sh... *** Running /etc/my_init.d/10_syslog-ng.init...

从以上日志看到缺失router.db这个文件，导致启动失败。解决方法在/data/oxidized目录下新建router.db文件，并在router.db随意添加一条记录。后重新启动容器
[root@node1 oxidized]# touch router.db
[root@node1 oxidized]# cat router.db
192.168.1.1:vrp:admin:admin [root@node1 oxidized]# docker restart oxidized oxidized [root@node1 oxidized]#
再次查看日志
[root@node1 data]# docker logs oxidized
......省略

修改配置文件
router.db是记录设备备份配置的本地信息文件
x.x.x.x:device type:username:password 10.10.24.241:ios:admin:password 10.10.28.235:comware:admin:password 10.10.0.107:vrp:admin:password
注解：device对应的是容器目录/var/lib/gems/2.5.0/gems/oxidized-0.26.3/lib/oxidized/model/的文件名
config文件
--- username: username : 用户名 这个参数不用改，会从router.db读取. password: password : 密码 这个参数也不用改，会从router.db读取. model: junos : 模型 这个参数也不用改，会从router.db读取. interval: 3600 : 备份周期 单位是秒，也就是默认一个小时备份一次 log: /home/oxidized/.config/oxidized/logs/oxidized.log:日志 debug: false ：debug模式 threads: 30 :线程 timeout: 20 : 超时 retries: 3 : 重试次数 prompt: !ruby/regexp /^([\w.@-]+[#>]\s?)$/ rest: 127.0.0.1:8888 :web 用到 next_adds_job: false vars: {} groups: {} models: {} pid: "/home/oxidized/.config/oxidized/pid" input: 连接设备模式 default: ssh, telnet debug: false ssh: secure: false output: 导出配置模式 default: file file: directory: "/home/oxidized/.config/oxidized/configs" source: default: csv csv: file: "/home/oxidized/.config/oxidized/router.db" delimiter: !ruby/regexp /:/ map: 这个地方和router.db里面的参数对应 从0开始 name: 0 model: 1 username: 2 password: 3 gpg: false model_map: cisco: ios juniper: junos
把rest:127.0.0.1:888修改成0.0.0.0:8888。重启容器，就可以访问web页面了。
