# 实现脚本自动备份Gitlab档案并同步到远程 #

> 参考：[Gitlab的备份与恢复][Gitlab]

## Gitlab服务器与备份服务器进行密钥配对，免密使用scp传输Gitlab备份文件 ##

> Gitlab Server: 192.168.0.55  
> Bakcup SWerver: 192.168.0.222

*  在Gitlab服务器上生产密钥对

ssh-keygen -t rsa

*  拷贝Gitlab上的公钥上传到备份服务器的指定目录（~/.ssh/authorized\_keys）:默认为当前用户的.ssh/authorized\_keys文件内，笔者使用的是root账户

# 在gitlab上执行，如果端口不是默认的22，采用scp的方式拷贝gitlab公钥
    ssh-copy-id root@192.168.0.222

## 定时执行脚本（crontab） ##

*  编辑/etc/crontab

# 在crontab文件中添加对应定时任务
    # Example of job definition:
    # .---------------- minute (0 - 59)
    # | .------------- hour (0 - 23)
    # | | .---------- day of month (1 - 31)
    # | | | .------- month (1 - 12) OR jan,feb,mar,apr ...
    # | | | | .---- day of week (0 - 6) (Sunday=0 or 7) OR sun,mon,tue,wed,thu,fri,sat
