主要配置文件

/etc/gitlab/gitlab-secrets.json：（执行gitlab-ctl reconfigure命令行后生成），包含各类密钥的加密信息
设置备份
# cat /etc/gitlab/gitlab.rb |grep -v "#" |grep -Ev '^$'
gitlab_rails['backup_path'] = "/backups" #备份的目录
gitlab_rails['backup_archive_permissions'] = 0644 #备份包（tar格式压缩包）的权限
gitlab_rails['backup_keep_time'] = 604800 #备份的保留时间，单位是秒 7天【随便搞个吧 反正是全量备份】
# gitlab-ctl reconfigure #重载配置，使之生效
挂载nas

定时备份

[root@gitlab backups]# systemctl restart crond.service
还原数据
特别注意：
- 备份目录和gitlab.rb中定义的备份目录必须一致
- GitLab的版本和备份文件中的版本必须一致，否则还原时会报错。
# cat /etc/gitlab/gitlab.rb |grep "backup_path" |grep -Ev "^$" # 确认备份目录
gitlab_rails['backup_path'] = "/backups"
# ll /backups/ # 确认备份文件
