华为/H3C交换机配置自动备份到FTP/SFTP

为优化建设内网的网管交换机，实现华为交换机和H3C交换机的配置自动备份，方便回溯以往配置过的CLI命令。此例将备份到FTP/SFTP服务端

注意事项

1、华为交换机的save-configuration的自动备份是以当前配置是否变更为基准，即当前配置没有变化的情况下，不会执行定时备份。此配置与H3C交换机不同
2、H3C交换机的archive configuration的自动备份是强制做定时备份，无论当前配置是否变更都会执行定时备份
3、华为数通智选系列和华为系列的S1730S-A1/A2版本在开机之后不能配置自动备份命令，需提前写好命令并加载到ROM层，使之开机生效

华为交换机配置自动备份

# cpu使用率低于45%, 配置修改时1分钟后自动备份1次, 正确情况下每隔1440分钟自动备份1次（即1天备份1次）
set save-configuration cpu-limit 45 delay 1 interval 1440

# SFTP协议, 备份服务端1.1.1.1, SFTP连接端口12345, SFTP用户是configbackup, SFTP用户密码是abcdefg, SFTP备份路径是/config/Switch
set save-configuration backup-to-server server 1.1.1.1 transport-type sftp port 12345 user configbackup password abcdefg path /config/Switch

H3C交换机配置自动备份

# 实验过的部分交换机型号如下
1. H3C S5024PV3-LI-PWR
2. H3C S5024PV3-EI-PWR
3. H3C S5024PV5

# SCP协议, SCP服务端是1.1.1.1 SCP连接端口12345, SCP备份路径是/config/Switch, 文件前缀是xxx
archive configuration server scp 1.1.1.1 port 12345 directory /config/Switch/ filename-prefix xxx

# SCP用户是configbackup
archive configuration server user configbackup

# SCP用户密码是abcdefg
archive configuration server password simple abcdefg

# SCP备份间隔1440分钟（即1天备份1次）
archive configuration interval 1440
