Backup and Recovery Guide for GitLab under CentOS System

This article details how to backup and restore GitLab on CentOS system to ensure that your GitLab data is safe and reliable.

Backup process

1. Create a backup:

   Use the command gitlab-rake gitlab:backup:create to create a complete backup of GitLab, including all key information such as Git repository, database, users, user groups, keys and permissions.

   The default backup file is stored in the /var/opt/gitlab/backups directory. You can change the backup storage path by modifying gitlab_rails['backup_path'] configuration item in the /etc/gitlab/gitlab.rb file.

   It is recommended to configure automatic backups, such as performing backup tasks in the early hours of every day.

2. Timed backup:

   Use the crontab tool to set up timed backup tasks. For example, a backup command can be executed at 2 a.m. every day.

3. Backup management:

   By modifying the gitlab.rb configuration file, you can manage backup path, retention time and other parameters. Regularly check the integrity and availability of backup files to ensure that backup data can be restored normally.

Recovery process

1. Stop service:

   For data consistency, GitLab service must be stopped before recovery, including unicorn and sidekiq processes.

2. Restore backup:

   Copy the backup file to the /var/opt/gitlab/backups directory.

   Use the command gitlab-rake gitlab:backup:restore to restore the backup. You need to specify the number of the backup file.

   The system will prompt to confirm whether to overwrite the existing data and enter yes to confirm the overwrite.

3. Start the service:

   After the recovery is complete, restart the previously stopped GitLab service.

4. Verification recovery:

   Visit the GitLab web interface to check whether it can be accessed normally.

   Verify data integrity, including warehouses, user data and configurations.

Important tips:

• The GitLab version that restores the backup must be consistent with or higher than the backup version.
• The backup file may contain sensitive information, please keep it safe.
• Regular recovery process tests are performed to ensure backup files are available.
