Gitlab 成功執行起來之後，最終的事情就是定期的備份，遇到問題後的還原。

備份配置

預設 Gitlab 的備份檔案會建立在/var/opt/gitlab/backups資料夾中，格式為時間戳_日期_版本號_gitlab_backup.tar，例如：1515031353_2018_01_04_10.3.2_gitlab_backup.tar。
修改備份資料夾，需要修改配置檔案/etc/gitlab/gitlab.rb中的：

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

然後gitlabctl-reconfigure生效。

手動備份

命令：gitlab-backup create

For GitLab 12.1 and earlier, use

gitlab-rake gitlab:backup:create

會在命令執行的時間點，在你配置的資料夾或者預設資料夾建立一個備份檔案。

自動備份

0 2 * * * /opt/gitlab/bin/gitlab-backup create CRON=1

備份恢復

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

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.
