一 备份gitlab为完整压缩包

# 在目录/var/opt/gitlab/backups/ 创建备份文件
gitlab-rake gitlab:backup:create

/var/opt/gitlab/backups/
1559614181_2019_06_04_10.7.7_gitlab_backup.tar

查看备份文件夹容量

 df -h /var/opt/gitlab/backups

二 恢复gitlab

复制gitlab_backup.tar到对应备份目录下

1 将备份文件权限修改为777

chmod 777 1559614181_2019_06_04_10.7.7_gitlab_backup.tar

2 停止相关数据连接服务

gitlab-ctl stop unicorn
gitlab-ctl stop sidekiq

3 执行命令从备份文件中恢复Gitlab

gitlab-rake gitlab:backup:restore BACKUP=备份文件编号
gitlab-rake gitlab:backup:restore BACKUP=1559614181_2019_06_04_10.7.7
输入2次yes

4 启动Gitlab

sudo gitlab-ctl start

三 定时备份Linux文件到windows

1 设置定时备份

编辑文件 /etc/crontab 最后一行加入，记得加用户名

# 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
# |  |  |  |  |
# *  *  *  *  * user-name  command to be executed

0 2  *  *  6 root /opt/gitlab/bin/gitlab-rake gitlab:backup:create CRON=1

每周六2点，新备份文件会存于备份文件夹 /var/opt/gitlab/backups/

2 设置备份过期时间

设置只保存最近7天的备份，编辑 /etc/gitlab/gitlab.rb

gitlab_rails['backup_keep_time'] = 604800  

sudo gitlab-ctl reconfigure

3 Windows下用sftp+脚本自动下载Linux备份文件夹

3.1 windows安装putty

在http://www.chiark.greenend.org.uk/~sgtatham/putty/download.html下载putty工具包putty-64bit-0.71-installer.msi
，在win安装，则cmd可运行psftp.exe

3.2 建立psftp配置文件和下载脚本

在E:\85gitlab_backup创建2个文件：sftp.txt和gitlab_backup.bat
sftp.txt

lcd E:/85gitlab_backup
get -r /var/opt/gitlab/backups
bye

gitlab_backup.bat

@echo off
psftp  192.168.0.85 -l root -pw root -b  "E:/85gitlab_backup/sftp.txt"

3.3 建立计划任务，定时运行脚本
