隨着網絡設備的增多，通過人手備份網絡設備倍感壓力，而且效率低。有編程基礎的人可能會通過Python的parimiko 或者netmiko 連接到設備操作 把文件通過ftp 上傳到FTP服務器, 在通過定時任務,定期自動備份。這個應該是現階段主流非人民幣網絡玩家的最優解決方案。
今天我們來看看oxidized這個被稱之為“最好用的”網絡備份系統，友好的支持不同廠商。
oxidized簡介
oxidized 是一個網絡設備備份系統, 輕量級,可擴展,支持超過90多個操作系統。個人覺得它無與倫比的優勢, 同時支持h3c,華為,思科。
隨着容器化的興起，部署軟件變得的越來越簡單，有的已經幫您封裝好，你開箱即用就可以了。好了下面，我們看看這個oxidized系統有沒有鏡像的。

把官方的 oxidized/oxidized 鏡像拉下來
[root@node1 ~]# docker pull oxidized/oxidized:latest
下載完啟動鏡像
[root@node1 data]# docker run --name='oxidized' -itd -v /data/oxidized:/root/.config/oxidized -p 8888:8888/tcp -t oxidized/oxidized
4bbb01b608e38c59469b1056e24c65f1f36f6e65b0734ab1e86b64b4efcf3306
說明一下：掛載本地/data/oxidized目錄到容器內的/root/.config/oxidized目錄下，將本地8888端口映射到容器的tcp8888端口。
查看是否已經啟動完
[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...

從以上日志看到缺失router.db這個文件，導致啟動失敗。解決方法在/data/oxidized目錄下新建router.db文件，並在router.db隨意添加一條記錄。后重新啟動容器
[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是記錄設備備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對應的是容器目錄/var/lib/gems/2.5.0/gems/oxidized-0.26.3/lib/oxidized/model/的文件名
config文件

把rest:127.0.0.1:888修改成0.0.0.0:8888。重啟容器，就可以訪問web頁面了。
