gitlab 备份&恢复

Gitlab 成功运行起来之后，最终的事情就是定期的备份，遇到问题后的还原。

备份配置

默认 Gitlab 的备份文件会创建在/var/opt/gitlab/backups文件夹中，格式为时间戳_日期_版本号_gitlab_backup.tar，例如：1515031353_2018_01_04_10.3.2_gitlab_backup.tar。

修改备份文件夹，需要修改配置文件/etc/gitlab/gitlab.rb中的：

gitlab_rails['backup_path'] = '/your_wish/backups'

然后gitlabctl-reconfigure生效。

手动备份

命令：gitlab-backup create

For GitLab 12.1 and earlier, use

gitlab-rake gitlab:backup:create

会在命令执行的时间点，在你配置的文件夹或者默认文件夹创建一个备份文件。

自动备份

备份恢复

First make sure your backup tar file is in the backup directory described in the gitlab.rb configuration gitlab_rails['backup_path']. The default is /var/opt/gitlab/backups. It needs to be owned by the git user.

cp 11493107454_2018_04_25_10.6.4-ce_gitlab_backup.tar /var/opt/gitlab/backups/
chown git.git /var/opt/gitlab/backups/11493107454_2018_04_25_10.6.4-ce_gitlab_backup.tar

Stop the processes that are connected to the database. Leave the rest of GitLab running:

gitlab-ctl stop unicorn
gitlab-ctl stop sidekiq
# Verify
gitlab-ctl status

Next, restore the backup, specifying the timestamp of the backup you wish to restore:

# This command will overwrite the contents of your GitLab database!
gitlab-backup restore BACKUP=1493107454_2018_04_25_10.6.4-ce

For GitLab 12.1 and earlier, use

gitlab-rake gitlab:backup:restore

Next, restore /etc/gitlab/gitlab-secrets.json if necessary as mentioned above.

Reconfigure, restart and check GitLab:

gitlab-ctl reconfigure
gitlab-ctl restart
gitlab-rake gitlab:check SANITIZE=true

If there is a GitLab version mismatch between your backup tar file and the installed version of GitLab, the restore command will abort with an error. Install the correct GitLab version and try again.
