Preparing Your Environment for Backup

Choosing a Suitable GitLab Instance

Selecting the right GitLab instance is crucial for a smooth backup and restoration process. When considering an instance on AWS, it’s important to assess the size of your user base and the complexity of your projects. Reference architectures for different scales, from a single node instance for up to 1,000 users to larger setups for up to 50,000 users, provide guidance on the infrastructure needed.

  • For small teams or individual use:
    • Single node GitLab instance
  • For medium to large teams:
    • Multi-node GitLab instance with dedicated resources

Italics are used for emphasis when necessary.

Ensure that the chosen instance aligns with your operational requirements and has the capacity to handle your current and future workload.

Configuring GitLab involves user management, repository management, CI/CD, migration from cloud to self-hosted, security considerations, and limitations. Requires technical expertise for self-hosting.

Verifying AWS Region and Backup Storage

Before proceeding with the restoration of your GitLab instance, it’s crucial to ensure that your AWS environment is correctly configured. Verify that the destination GitLab instance is located in the same AWS region where your backups are stored. This is essential for a seamless restoration process as AWS backups can only be restored within their respective regions.

To configure your AWS backup settings, follow these steps:

  • Configure AWS Backup for continuous and snapshot backups of RDS and S3 data.
  • Set up AWS Backup to replicate backups to a separate region for added redundancy.
  • After the initial scheduled backup, create on-demand backups as necessary.

Ensure that the IAM role used for restoration has the appropriate permissions, including policies for backup and restore operations specific to S3.

Lastly, fill in the storage details form with your S3 and IAM user information, ensuring that Access Control Lists are enabled if existing buckets are used. This preparation is key to a smooth restoration of your GitLab repositories and databases.

Matching GitLab Versions and Types

Ensuring that the version of GitLab you are restoring from a backup matches the version you are restoring to is crucial. Version mismatches can lead to data corruption or loss, so it’s important to verify this before proceeding. Check both the source and target GitLab instances for their respective versions.

When dealing with different GitLab types, such as GitLab Community Edition (CE) and GitLab Enterprise Edition (EE), compatibility is key. You cannot restore a backup from EE to CE, as EE contains additional features that are not present in CE. Use the following list to guide you:

  • CE to CE: Compatible
  • EE to EE: Compatible
  • EE to CE: Not compatible
  • CE to EE: Compatible (with possible limitations)

Remember to also consider any custom configurations or integrations that may be specific to your GitLab setup. These need to be replicated or adapted to the new environment to ensure a seamless restoration process.

Configuring Repository Storages

Before initiating a backup, it’s crucial to ensure that your destination GitLab instance mirrors the repository storages of the source. This alignment is key to a seamless restoration process. If your backup includes blobs in object storage, the corresponding configurations must be in place. Similarly, for file system blobs, NFS should be configured to match the source setup.

GitLab Ultimate users may have additional storages or complex configurations, which should be carefully replicated on the destination instance. Here’s a quick checklist to help you align your repository storages:

  • Verify that all repository storages from the source are present on the destination.
  • Configure object storage for blobs if they were used in the source.
  • Set up NFS for file system blobs to ensure accessibility.

Remember, additional storages on the destination are acceptable, but the core storages must be consistent with the source.

To back up Git repositories effectively, configure a server-side backup destination on all Gitaly nodes and include the destination bucket in your object storage data backups. This preparation will facilitate a full backup of your Git data, focusing on the repositories while skipping the PostgreSQL data when necessary.

Creating a Complete GitLab Backup

Creating a Complete GitLab Backup

Navigating to the GitLab Directory

Before initiating a backup, it’s crucial to navigate to the correct GitLab directory where the application code and data reside. This is typically found at /usr/share/webapps/gitlab or /var/lib/gitlab, depending on your installation. Ensure you’re operating in the directory that contains the config and log subdirectories to avoid any backup inconsistencies.

For GitLab Premium users, additional features may be available to assist with the backup process. It’s important to consult the official documentation for any premium-specific procedures.

To access the GitLab directory, you can use the following commands:

  1. Change to the GitLab user (if applicable):
    sudo su - gitlab
  2. Navigate to the application directory:
    cd /usr/share/webapps/gitlab or cd /var/lib/gitlab

Remember, the exact path may vary based on your system’s configuration and the method used during the GitLab installation. Always verify the path before proceeding with the backup.

Executing the Backup Command

Once you’re in the GitLab directory, it’s time to execute the backup command. Ensure you run the command as the git user to avoid any permission issues. The command will look something like this:

sudo -u git BACKUP=timestamp_gitlab_backup.tar bundle exec rake gitlab:backup:create

After the command completes, you’ll receive a backup ID, which is crucial for the restoration process. For instance, if the output is Backup 1708568263_2024_02_22_16.9.0-ce is done., the backup ID is 1708568263_2024_02_22_16.9.0-ce. Make a note of this ID.

It’s essential to verify that the backup was successful and that the data has been stored correctly. Check the backup directory or bucket to ensure the backup file is present and correctly named.

If you’re planning to perform an incremental backup, remember to specify the INCREMENTAL=yes flag and provide the PREVIOUS_BACKUP ID when running the backup command again.

Handling Special Cases with PgBouncer and Patroni Clusters

When dealing with PgBouncer and Patroni clusters, it’s crucial to ensure that your backup and restore processes account for the specific configurations and requirements of these systems. Backups must be consistent across all nodes to prevent any data discrepancies during the restoration phase.

For PgBouncer, a connection pooler, you’ll need to temporarily disable new connections to avoid conflicts. Here’s a simple checklist to follow:

  • Pause traffic to PgBouncer.
  • Perform the backup.
  • Resume traffic once the backup is complete.

Patroni, which handles automatic failover and high-availability, requires a bit more attention. Ensure that the backup is taken from the primary node and that the cluster is in a healthy state before proceeding. After the backup, Patroni’s replication settings might need reconfiguration to reflect the restored state.

It’s essential to verify that the backup includes all necessary components such as configuration files, databases, and repositories. Incomplete backups can lead to a failed restoration process.

Lastly, remember to configure database credentials for accessibility and redundancy. GitLab provides powerful tools for database management and migration, offering seamless workflows, collaboration, and version control.

Restoring Your GitLab Backup

Restoring Your GitLab Backup

Identifying the Backup File

Once you’ve completed a backup, the next critical step is to identify the backup file you’ll use for restoration. This file is typically a .tar archive, containing all the necessary components of your GitLab instance. To locate your backup file, you’ll need to access the backup directory specified in your gitlab.rb configuration, usually found at /var/opt/gitlab/backups. Ensure the file is owned by the git user to avoid permission issues during the restore process.

The backup file’s name includes the backup ID, which is crucial for the restoration command. For example, a file named 11493107454_2018_04_25_10.6.4-ce_gitlab_backup.tar indicates the backup ID and the GitLab version it was created with.

Follow these steps to prepare for restoration:

  1. Download the backup .tar file from its storage location to the backup directory.
  2. Verify the ownership of the file using sudo chown git:git /path/to/backup_file.
  3. Note the backup ID, as you will need it to initiate the restore process.

Overwriting the GitLab Database

Once you’ve identified the backup file, the next critical step is to overwrite the existing GitLab database with the backup. This is a delicate operation and should be approached with caution. Ensure that all services that access the database are stopped before proceeding to prevent any data corruption or loss.

To overwrite the GitLab database, follow these steps:

  1. Start by stopping all GitLab services except for PostgreSQL:
    sudo gitlab-ctl stop

  2. Next, restore the database using the backup file:
    sudo gitlab-backup restore BACKUP=timestamp_of_backup

  3. After the restoration, start all the GitLab services:
    sudo gitlab-ctl start

Remember to check the database configuration for any changes, especially if you’re working with a version of GitLab that has recently updated its database configuration syntax. The database.yml file may require updates to match the new structure.

It’s crucial to verify that the database restoration has completed successfully before making GitLab available to users again. Any discrepancies can lead to significant issues down the line.

Dealing with GitLab Version Mismatches

When restoring a GitLab backup, it’s crucial to ensure that the GitLab version of your backup matches the version of the instance you’re restoring to. Version mismatches can lead to data corruption or loss, and must be handled with care. If you encounter a version discrepancy, follow these steps:

  1. Identify the version of your backup by checking the backup filename, which typically includes the version number.
  2. Find your GitLab version on the destination instance by navigating to the ‘Help’ page or using the command line.
  3. If the versions do not match, you may need to upgrade or downgrade the destination instance before proceeding with the restore.

Remember, it’s better to prevent issues than to fix them. Always double-check the version compatibility before initiating a restore.

In some cases, you might need to perform an intermediate upgrade to align the versions. This process involves restoring the backup to a temporary GitLab instance with the same version as the backup, then upgrading that instance to match the destination version. Once aligned, you can proceed with the final restoration.

Restoring Git Repositories

Restoring Git Repositories

Ensuring Sufficient Storage Space

Before initiating the restoration of your GitLab repositories, it’s crucial to ensure that your system has sufficient storage space. This step is vital to prevent any interruptions due to space constraints during the restoration process. To estimate the required space, consider the size of your backup files and the additional overhead for the restoration operation.

  • Check the size of the backup file
  • Account for extra space needed during restoration
  • Monitor disk space usage throughout the process

It’s recommended to have at least as much free space as the size of the backup file, plus an additional 10-20% to accommodate the restoration overhead.

Failure to secure enough storage can lead to incomplete restoration or data corruption. Therefore, it’s essential to perform a thorough check and clean up any unnecessary files prior to proceeding. This proactive approach will help ensure a smooth and successful restoration of your GitLab data.

Restoring Object Storage Data

When it comes to restoring object storage data, it’s crucial to understand that each bucket in AWS is backed up separately and can be restored individually to an existing or new bucket. This granularity allows for precise restoration of artifacts, uploads, packages, registry, and LFS objects.

For those using Google Cloud Storage (GCS), the process involves creating backup buckets and configuring Storage Transfer Service jobs to copy data from GitLab’s object storage buckets. These jobs can be scheduled to run daily, ensuring a regular backup routine. However, be aware that this method may retain deleted files from GitLab in the backup, potentially leading to unnecessary storage usage post-restore.

It’s important to verify the success of incremental backups, as they add data to object storage. Regular checks and configurations, such as setting up cron jobs for daily backups, are essential for maintaining the integrity of your backup system.

Here’s a quick checklist to ensure your object storage data is restored correctly:

  • Verify each AWS bucket backup integrity.
  • Create and configure GCS backup buckets.
  • Schedule and monitor Storage Transfer Service jobs.
  • Check for orphaned files to prevent storage waste.
  • Confirm the success of incremental backups.

Running the Restore Command

Once you’ve ensured sufficient storage space and restored object storage data, it’s time to run the restore command. This is a critical step that will overwrite the contents of your GitLab database, so proceed with caution. Use the following command, replacing BACKUP with the ID of the backup you wish to restore:

sudo gitlab-backup restore BACKUP=1556571328_2019_04_29_11.10.2

Remember, if your installation uses PgBouncer or is part of a Patroni cluster, additional parameters are required.

After executing the command, verify that the process completes without errors. In case of a GitLab version mismatch, the restore command will abort with an error message. To resolve this, install the correct GitLab version and attempt the restore again.

For Linux package installations, select a Rails node to perform the restore. This node typically runs Puma or Sidekiq, which are essential for the restoration process.

Post-Restoration Configuration

Restoring Backed Up Secrets

After ensuring that your GitLab instance is prepared for restoration, the next critical step is to restore the backed up secrets. These secrets are vital for the operation of your GitLab instance and include sensitive information such as passwords, tokens, and encryption keys. It’s essential to handle this data with care to maintain the security and functionality of your system.

To restore secrets, particularly when dealing with /etc/gitlab/gitlab-secrets.json, verify that the database values can be decrypted. This is crucial if you’re restoring to a different server or if you’ve just restored the secrets file. For Linux package installations, execute sudo gitlab-rake gitlab:doctor:secrets on a Puma or Sidekiq node. For Helm chart installations on Kubernetes, run the same command within the Toolbox pod.

Ensure that the restored secrets match the requirements of the target GitLab instance. Any mismatch in the secrets can lead to service disruptions or loss of data integrity.

If your secrets are stored and managed externally, such as in AWS Secret Manager, make sure to follow your established backup strategy. This might involve automatic replication to multiple regions and a script to back up secrets. Always store your configuration and secrets files in a secure, restricted object storage account to prevent unauthorized access.

Remember, the successful restoration of secrets is a foundational step in the recovery of your GitLab environment. Without it, subsequent steps may fail, and the integrity of your GitLab instance could be compromised.

Enabling Fast SSH Key Lookup

To enhance the performance of SSH operations within GitLab, enabling fast SSH key lookup is crucial. This optimization reduces the time taken to authenticate SSH sessions, especially when dealing with a large number of users and keys. The process involves editing the /etc/ssh/sshd_config file to ensure that the GitLab user is properly configured and that the AuthorizedKeysFile directive points to the correct location.

GitLab documentation provides a comprehensive guide on this topic, which can be found at their official documentation page. It’s important to follow these instructions carefully to avoid any disruptions in service.

Ensure that the PubkeyAuthentication option is set to yes and that the AuthorizedKeysFile is %h/.ssh/authorized_keys.

After making the necessary changes, remember to restart the sshd.service to apply the new configuration. Testing the SSH keys with ssh -T git@your_server can confirm if the setup is correct. If you encounter any issues, the gitlab-shell.log at /var/lib/gitlab/log/ is a good place to start troubleshooting.

Verifying Data Integrity with Rake Tasks

After restoring your GitLab instance, it’s crucial to verify the integrity of your data. GitLab’s Rake tasks provide a comprehensive suite of checks to ensure everything is in order. For instance, you can use gitlab:check to perform a general health check of your GitLab environment, which includes tests, deployments, and logs, contributing to system stability and security.

To verify specific components, you can run the following commands:

  • gitlab:artifacts:check to check the integrity of build artifacts
  • gitlab:lfs:check for verifying Large File Storage objects
  • gitlab:uploads:check to ensure that uploads are intact

For Helm chart installations, these tasks should be executed on the GitLab Rails node to avoid long execution times. Remember to use the SANITIZE=true option with gitlab:check to prevent sensitive data from being displayed in the output.

It’s a good practice to regularly monitor these aspects of your GitLab instance, not just after a restoration. This proactive approach helps in maintaining a secure and stable environment.

Incremental Backup and Restoration

Incremental Backup and Restoration

Taking an Incremental Backup of Git Data

Incremental backups are essential for maintaining an up-to-date and efficient backup system. Boldly speaking, they save time and storage space by only updating the changes made since the last full backup. To perform an incremental backup of your Git data, follow these steps:

  1. Ensure you have a full backup of your Git data. Use the REPOSITORIES_SERVER_SIDE=true flag and skip the PostgreSQL data with SKIP=db.
  2. Run the backup command again, this time specifying the incremental backup and a backup ID. For example:
    sudo gitlab-backup create REPOSITORIES_SERVER_SIDE=true SKIP=db INCREMENTAL=yes PREVIOUS_BACKUP=1708568263_2024_02_22_16.9.0-ce
    

Remember, the PREVIOUS_BACKUP value is a placeholder and currently not used by the command due to an existing issue.

To automate this process, consider adding a cron job that schedules full backups monthly and incremental backups daily. This ensures a balance between backup comprehensiveness and resource utilization.

Specifying the Backup ID for Incremental Backups

Once you’ve completed a full backup, noting the backup ID is crucial for the incremental backup process. This ID uniquely identifies your backup and is required for subsequent incremental backups. For instance, if the output of your backup command is 2024-02-22 02:17:47 UTC -- Backup 1708568263_2024_02_22_16.9.0-ce is done., the backup ID would be 1708568263_2024_02_22_16.9.0-ce.

To initiate an incremental backup, you’ll use a command similar to the following, replacing PREVIOUS_BACKUP with your noted backup ID:

sudo gitlab-backup create REPOSITORIES_SERVER_SIDE=true SKIP=db INCREMENTAL=yes PREVIOUS_BACKUP=1708568263_2024_02_22_16.9.0-ce

Remember, the PREVIOUS_BACKUP value is a placeholder and is not actively used by the command. However, it’s a mandatory parameter due to current GitLab requirements, with discussions ongoing to potentially remove this necessity in the future.

When setting up your GitLab CI/CD, consider the incremental backup as part of your pipeline’s ‘stages’ and ‘jobs’. This ensures that your backup strategy is integrated into your development workflow, providing a seamless safety net for your repositories.

Restoring from an Incremental Backup

Restoring from an incremental backup is a critical step in ensuring that your GitLab data is up-to-date with the latest changes. Ensure that you have the ID of the incremental backup you wish to restore, as this will be required during the restoration process. The command to restore an incremental backup is similar to a full backup but includes additional flags to specify the incremental nature.

To perform the restoration, use the following command, replacing BACKUP_ID with your specific backup ID:

sudo gitlab-backup restore BACKUP=BACKUP_ID

Remember, this action will overwrite the contents of your GitLab database, so proceed with caution.

After the restoration, it’s essential to verify that all data has been correctly restored and that there are no discrepancies. Testing restore procedures periodically can help you become familiar with the process and reduce the risk of errors during an actual recovery scenario.
