Let's talk about how gitlab recovers data

With the widespread use of GitLab in the open source community and developers, the increasing importance of GitLab has made it an indispensable part of the development team because it provides a platform for collaborative code development and project management. However, if something goes wrong or is damaged in GitLab, how can we restore GitLab?

This article will introduce how to recover GitLab from Disaster Recovery. In this article, we’ll discuss some of the most common GitLab disasters and explain how to secure your GitLab instance to keep your data safe.

1. Backup GitLab

First of all, it is very important to back up GitLab. Through regular backups, we can ensure that we can recover the data if GitLab fails. In order to back up GitLab, we can use GitLab's own backup program, which can create a tar.gz file containing all GitLab configuration and data. We can create a GitLab backup by running the following command:

sudo gitlab-rake gitlab:backup:create

This command will create a backup file in the GitLab installation root directory. We recommend storing backup files in an external location or uploading them to a cloud storage service in case of a hardware failure or disaster on the GitLab server.

2. Backup and Recovery

If GitLab fails or data is lost, we need to use backup files for recovery. We can restore GitLab from the backup file using the following command:

sudo gitlab-rake gitlab:backup:restore BACKUP=

where "backup_file" is the name of the backup file we created . We can use this command to restore GitLab database and code repository.

3. Database recovery

GitLab data is stored in the PostgreSQL database. If there is a problem with the GitLab database, we need to perform database recovery. We can restore the GitLab database by following the steps below.

First, stop all services of the GitLab server:

sudo gitlab-ctl stop unicorn
sudo gitlab-ctl stop sidekiq
sudo gitlab-ctl stop nginx

Then, back up the database data:

sudo gitlab-rake gitlab:backup:create

Next, we need to restore the database from the backup:

sudo gitlab-rake gitlab :db:drop
sudo gitlab-rake gitlab:db:create
sudo gitlab-rake gitlab:backup:restore BACKUP=

After restoring from the backup file, we need to restart Start all GitLab services:

sudo gitlab-ctl start

4. Git repository recovery

GitLab's code repository is located at /var/opt/gitlab /git-data/repositories directory, if the repository becomes corrupted, we can use the backup to restore it. We can restore the GitLab repository by following the steps:

First, stop all services of the GitLab server:

sudo gitlab-ctl stop unicorn
sudo gitlab-ctl stop sidekiq
sudo gitlab-ctl stop nginx

Then, backup the repository data:

sudo gitlab-rake gitlab:backup:create

Next, we need to restore the storage from the backup Library:

sudo rm -rf /var/opt/gitlab/git-data/repositories/.git
sudo gitlab-rake gitlab:backup:restore BACKUP=

Where "project_name" is the name of the repository we need to restore, and "backup_file" is the name of the backup file we created.

After restoring from the backup file, we need to restart all GitLab services:

sudo gitlab-ctl start

Summary:

In this article, We covered how to recover GitLab from disaster. Backing up GitLab is very important, we recommend backing up GitLab regularly and storing the backup data in a reliable location. Additionally, GitLab’s data can be quickly restored by using GitLab’s backup and restore program. If you encounter a problem with your GitLab server, by using these steps to recover, you can ensure the normal operation of GitLab and keep your data safe.
