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。
[root@node1 ~]# docker search oxidized

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

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

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
