1.为了能够备份和恢复，请确保你的系统上安装了Rsync
#Debian/Ubauntu sudo apt-get install rsync # RHEL/Centos sudo yum install rsync2.配置了与备份目标机器之间的免密认证
修改gitlab配置文件：vim /etc/gitlab/gitlab.rb
#指定备份后数据存放的路径、权限、时间配置 gitlab_rails['manage_backup_path'] = true #292行 开启备份功能 gitlab_rails['backup_path'] = "/opt/gitlab_backup" #293行 指定备份的路径 gitlab_rails['backup_archive_permissions'] = 0644 #296行 备份文件的权限 gitlab_rails['backup_keep_time'] = 7776000 #301行 备份保留时间（保留90天 单位：秒 创建备份目录并授权：mkdir /opt/gitlab_backups && chown -R git.git /opt/gitlab_backups/
重新生效Gitlabb配置：gitlab-ctl reconfigure

编写备份脚本，结合crontab实施自动定时备份，比如每天0点、6点、12点、18点各备份一次
编写备份脚本： #!/usr/bin/bash locale_date=`date +%Y-%m-%d_%H:%M:%S` backup_host=192.168.101.133 backup_path=http://www.likecs.com/opt/gitlab_backups/${locale_date} #CRON=1 环境变量CRON=1的作用是如果没有任何错误发生时， 抑制备份脚本的所有进度输出 #BACKUP=${locale_date}改变backup文件名称 例: 2021-06-15_11:22:52_gitlab_backup.tar /opt/gitlab/bin/gitlab-backup create BACKUP=${locale_date} CRON=1 ssh root@${backup_host} ls ${backup_path} > /dev/null 2\>\&1 if [ $? -eq 0 ];then scp ${backup_path}_gitlab_backup.tar root@${backup_host}:${backup_path} scp /etc/gitlab/gitlab-secrets.json root@${backup_host}:${backup_path} scp /etc/gitlab/gitlab.rb root@${backup_host}:${backup_path} else ssh root@${backup_host} mkdir -p ${backup_path} scp ${backup_path}_gitlab_backup.tar root@${backup_host}:${backup_path} scp /etc/gitlab/gitlab-secrets.json root@${backup_host}:${backup_path} scp /etc/gitlab/gitlab.rb root@${backup_host}:${backup_path} fi[root@gitlabdev ~]# chmod +x /opt/gitlab_backups/gitlab_back.sh
加入定时任务： crontab -e #添加定时任务 crontab -l #查看已添加定时任务 [root@gitlabdev ~]# crontab -l 0 0,6,12,18 * * * /bin/bash /opt/gitlab_backups/gitlab_back.sh > /dev/null 2>&1 GItlab只能还原到与备份文件相同的gitlab版本。
