GitLab默认的配置文件路径：/etc/gitlab/
- /etc/gitlab/gitlab.rb：主配置文件，包含外部URL、仓库目录、备份目录等
- /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

2 - 备份指令备份指令不会备份配置文件，需要手动备份配置目录和相关文件。
默认的备份目录为/var/opt/gitlab/backups/
以下是/etc/gitlab/gitlab.rb文件中Backup Settings部分的内容
379 ### Backup Settings
380 ###! Docs: https://docs.gitlab.com/omnibus/settings/backups.html

3 - 定时备份使用Crontab任务进行定时备份。
[root@test102 ~]# crontab -l no crontab for root [root@test102 ~]# [root@test102 ~]# crontab -e no crontab for root - using an empty one crontab: installing new crontab [root@test102 ~]# [root@test102 ~]# crontab -l 0 2 * * * /opt/gitlab/bin/gitlab-rake gitlab:backup:create CRON=10 2 * * * /opt/gitlab/bin/gitlab-rake gitlab:backup:create CRON=1 [root@test102 ~]#

4 - 备份到云存储从GitLab7.4开始，可以将备份文件上传到远端云存储上。
具体配置和操作，可查看官方文档：
涉及的配置项如下：
393 # gitlab_rails['backup_upload_connection'] = {
394 # 'provider' => 'AWS',
395 # 'region' => 'eu-west-1',
396 # 'aws_access_key_id' => 'AKIAKIAKI',
397 # 'aws_secret_access_key' => 'secret123'
398 # }
399 # gitlab_rails['backup_upload_remote_directory'] = 'my.s3.bucket'
400 # gitlab_rails['backup_multipart_chunk_size'] = 104857600

5 - 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。
