Backing up and restoring GitLab

An application data backup creates an archive file that contains the database, all repositories and all attachments.

You can only restore a backup to exactly the same version and type (CE/EE) of GitLab on which it was created. The best way to migrate your repositories from one server to another is through backup restore.

Requirements

In order to be able to backup and restore, you need two essential tools installed on your system.

Rsync

If you installed GitLab:

Using the Omnibus package, you're all set.

From source, make sure rsync is installed:

# Debian/Ubuntu
sudo apt-get install rsync

# RHEL/CentOS
sudo yum install rsync

Tar

Backup and restore tasks use tar under the hood to create and extract archives. Ensure you have version 1.30 or above of tar available in your system. To check the version, run:

tar --version

Backup timestamp

NOTE: Note: In GitLab 9.2 the timestamp format was changed from EPOCH_YYYY_MM_DD to EPOCH_YYYY_MM_DD_GitLab_version, for example 1493107454_2018_04_25 would become 1493107454_2018_04_25_10.6.4-ce.

The backup archive will be saved in backup_path, which is specified in the config/gitlab.yml file. The filename will be [TIMESTAMP]_gitlab_backup.tar, where TIMESTAMP identifies the time at which each backup was created, plus the GitLab version. The timestamp is needed if you need to restore GitLab and multiple backups are available.

For example, if the backup name is 1493107454_2018_04_25_10.6.4-ce_gitlab_backup.tar, then the timestamp is 1493107454_2018_04_25_10.6.4-ce.

Creating a backup of the GitLab system

GitLab provides a simple command line interface to backup your whole instance. It backs up your:

Database
Attachments
Git repositories data
CI/CD job output logs
CI/CD job artifacts
LFS objects
Container Registry images
GitLab Pages content

CAUTION: Warning: GitLab does not back up any configuration files, SSL certificates, or system files. You are highly advised to read about storing configuration files.

Use this command if you've installed GitLab with the Omnibus package:

sudo gitlab-rake gitlab:backup:create

Use this if you've installed GitLab from source:

sudo -u git -H bundle exec rake gitlab:backup:create RAILS_ENV=production

If you are running GitLab within a Docker container, you can run the backup from the host:

docker exec -t <container name> gitlab-rake gitlab:backup:create

If you are using the GitLab helm chart on a Kubernetes cluster, you can run the backup task using backup-utility script on the gitlab task runner pod via kubectl. Refer to backing up a GitLab installation for more details:

kubectl exec -it <gitlab task-runner pod> backup-utility

Storing configuration files

A backup performed by the raketask GitLab provides does not store your configuration files. The primary reason for this is that your database contains encrypted information for two-factor authentication, the CI/CD 'secure variables', etc. Storing encrypted information along with its key in the same place defeats the purpose of using encryption in the first place.

CAUTION: Warning: The secrets file is essential to preserve your database encryption key.

At the very minimum, you must backup:

For Omnibus:

/etc/gitlab/gitlab-secrets.json
/etc/gitlab/gitlab.rb

For installation from source:

/home/git/gitlab/config/secrets.yml
/home/git/gitlab/config/gitlab.yml

For Docker installations, you must back up the volume where the configuration files are stored. If you have created the GitLab container according to the documentation, it should be under /srv/gitlab/config.

You may also want to back up any TLS keys and certificates, and your SSH host keys.

If you use Omnibus GitLab, see some additional information to backup your configuration.

In the unlikely event that the secrets file is lost, see the troubleshooting section.

Backup options

The command line tool GitLab provides to backup your instance can take more options.

Backup strategy option

Introduced in GitLab 8.17.

The default backup strategy is to essentially stream data from the respective data locations to the backup using the Linux command tar and gzip. This works fine in most cases, but can cause problems when data is rapidly changing.

When data changes while tar is reading it, the error file changed as we read it may occur, and will cause the backup process to fail. To combat this, 8.17 introduces a new backup strategy called copy. The strategy copies data files to a temporary location before calling tar and gzip, avoiding the error.

A side-effect is that the backup process with take up to an additional 1X disk space. The process does its best to clean up the temporary files at each stage so the problem doesn't compound, but it could be a considerable change for large installations. This is why the copy strategy is not the default in 8.17.

To use the copy strategy instead of the default streaming strategy, specify STRATEGY=copy in the Rake task command. For example:

sudo gitlab-rake gitlab:backup:create STRATEGY=copy

Backup filename

By default a backup file is created according to the specification in the Backup timestamp section above. You can however override the [TIMESTAMP] part of the filename by setting the BACKUP environment variable. For example:

sudo gitlab-rake gitlab:backup:create BACKUP=dump

The resulting file will then be dump_gitlab_backup.tar. This is useful for systems that make use of rsync and incremental backups, and will result in considerably faster transfer speeds.

Rsyncable

To make sure the generated archive is intelligently transferable by rsync, the GZIP_RSYNCABLE=yes option can be set. This will set the --rsyncable option to gzip. This is only useful in combination with setting the Backup filename option.

Note that the --rsyncable option in gzip is not guaranteed to be available on all distributions. To verify that it is available in your distribution you can run gzip --help or consult the man pages.

sudo gitlab-rake gitlab:backup:create BACKUP=dump GZIP_RSYNCABLE=yes

Excluding specific directories from the backup

You can choose what should be exempt from the backup up by adding the environment variable SKIP. The available options are:

db (database)
uploads (attachments)
repositories (Git repositories data)
builds (CI job output logs)
artifacts (CI job artifacts)
lfs (LFS objects)
registry (Container Registry images)
pages (Pages content)

Use a comma to specify several options at the same time:

All wikis will be backed up as part of the repositories group. Non-existent wikis will be skipped during a backup.

For Omnibus GitLab packages:

sudo gitlab-rake gitlab:backup:create SKIP=db,uploads

For installations from source:

sudo -u git -H bundle exec rake gitlab:backup:create SKIP=db,uploads RAILS_ENV=production

Uploading backups to a remote (cloud) storage

Starting with GitLab 7.4 you can let the backup script upload the '.tar' file it creates. It uses the Fog library to perform the upload. In the example below we use Amazon S3 for storage, but Fog also lets you use other storage providers. GitLab imports cloud drivers for AWS, Google, OpenStack Swift, Rackspace and Aliyun as well. A local driver is also available.

Using Amazon S3

For Omnibus GitLab packages:

Add the following to /etc/gitlab/gitlab.rb:

gitlab_rails['backup_upload_connection'] = {
  'provider' => 'AWS',
  'region' => 'eu-west-1',
  'aws_access_key_id' => 'AKIAKIAKI',
  'aws_secret_access_key' => 'secret123'
  # If using an IAM Profile, don't configure aws_access_key_id & aws_secret_access_key
  # 'use_iam_profile' => true
}
gitlab_rails['backup_upload_remote_directory'] = 'my.s3.bucket'

Reconfigure GitLab for the changes to take effect

Digital Ocean Spaces

This example can be used for a bucket in Amsterdam (AMS3).

Add the following to /etc/gitlab/gitlab.rb:

gitlab_rails['backup_upload_connection'] = {
  'provider' => 'AWS',
  'region' => 'ams3',
  'aws_access_key_id' => 'AKIAKIAKI',
  'aws_secret_access_key' => 'secret123',
  'endpoint'              => 'https://ams3.digitaloceanspaces.com'
}
gitlab_rails['backup_upload_remote_directory'] = 'my.s3.bucket'

Reconfigure GitLab for the changes to take effect

NOTE: Note: If you see 400 Bad Request by using Digital Ocean Spaces, the cause may be the usage of backup encryption. Remove or comment the line that contains gitlab_rails['backup_encryption'] since Digital Ocean Spaces doesn't support encryption.

Other S3 Providers

Not all S3 providers are fully-compatible with the Fog library. For example, if you see 411 Length Required errors after attempting to upload, you may need to downgrade the aws_signature_version value from the default value to 2 due to this issue.

For installations from source:

Edit home/git/gitlab/config/gitlab.yml:

  backup:
    # snip
    upload:
      # Fog storage connection settings, see http://fog.io/storage/ .
      connection:
        provider: AWS
        region: eu-west-1
        aws_access_key_id: AKIAKIAKI
        aws_secret_access_key: 'secret123'
        # If using an IAM Profile, leave aws_access_key_id & aws_secret_access_key empty
        # ie. aws_access_key_id: ''
        # use_iam_profile: 'true'
      # The remote 'directory' to store your backups. For S3, this would be the bucket name.
      remote_directory: 'my.s3.bucket'
      # Turns on AWS Server-Side Encryption with Amazon S3-Managed Keys for backups, this is optional
      # encryption: 'AES256'
      # Turns on AWS Server-Side Encryption with Amazon Customer-Provided Encryption Keys for backups, this is optional
      #   This should be set to the base64-encoded encryption key for Amazon S3 to use to encrypt or decrypt your data.
      #   'encryption' must also be set in order for this to have any effect.
      #   To avoid storing the key on disk, the key can also be specified via the `GITLAB_BACKUP_ENCRYPTION_KEY` environment variable.
      # encryption_key: '<base64 key>'
      # Specifies Amazon S3 storage class to use for backups, this is optional
      # storage_class: 'STANDARD'

Restart GitLab for the changes to take effect

If you are uploading your backups to S3 you will probably want to create a new IAM user with restricted access rights. To give the upload user access only for uploading backups create the following IAM profile, replacing my.s3.bucket with the name of your bucket:

{
  "Version": "2012-10-17",
  "Statement": [
    {
      "Sid": "Stmt1412062044000",
      "Effect": "Allow",
      "Action": [
        "s3:AbortMultipartUpload",
        "s3:GetBucketAcl",
        "s3:GetBucketLocation",
        "s3:GetObject",
        "s3:GetObjectAcl",
        "s3:ListBucketMultipartUploads",
        "s3:PutObject",
        "s3:PutObjectAcl"
      ],
      "Resource": [
        "arn:aws:s3:::my.s3.bucket/*"
      ]
    },
    {
      "Sid": "Stmt1412062097000",
      "Effect": "Allow",
      "Action": [
        "s3:GetBucketLocation",
        "s3:ListAllMyBuckets"
      ],
      "Resource": [
        "*"
      ]
    },
    {
      "Sid": "Stmt1412062128000",
      "Effect": "Allow",
      "Action": [
        "s3:ListBucket"
      ],
      "Resource": [
        "arn:aws:s3:::my.s3.bucket"
      ]
    }
  ]
}

Using Google Cloud Storage

If you want to use Google Cloud Storage to save backups, you'll have to create an access key from the Google console first:

Go to the storage settings page https://console.cloud.google.com/storage/settings
Select "Interoperability" and create an access key
Make note of the "Access Key" and "Secret" and replace them in the configurations below
Make sure you already have a bucket created

For Omnibus GitLab packages:

Edit /etc/gitlab/gitlab.rb:

gitlab_rails['backup_upload_connection'] = {
  'provider' => 'Google',
  'google_storage_access_key_id' => 'Access Key',
  'google_storage_secret_access_key' => 'Secret'
}
gitlab_rails['backup_upload_remote_directory'] = 'my.google.bucket'

Reconfigure GitLab for the changes to take effect

For installations from source:

Edit home/git/gitlab/config/gitlab.yml:

  backup:
    upload:
      connection:
        provider: 'Google'
        google_storage_access_key_id: 'Access Key'
        google_storage_secret_access_key: 'Secret'
      remote_directory: 'my.google.bucket'

Restart GitLab for the changes to take effect

Specifying a custom directory for backups

Note: This option only works for remote storage. If you want to group your backups you can pass a DIRECTORY environment variable:

sudo gitlab-rake gitlab:backup:create DIRECTORY=daily
sudo gitlab-rake gitlab:backup:create DIRECTORY=weekly

Uploading to locally mounted shares

You may also send backups to a mounted share (NFS / CIFS / SMB / etc.) by using the Fog Local storage provider. The directory pointed to by the local_root key must be owned by the git user when mounted (mounting with the uid= of the git user for CIFS and SMB) or the user that you are executing the backup tasks under (for omnibus packages, this is the git user).

The backup_upload_remote_directory must be set in addition to the local_root key. This is the sub directory inside the mounted directory that backups will be copied to, and will be created if it does not exist. If the directory that you want to copy the tarballs to is the root of your mounted directory, just use . instead.

NOTE: Note: Since file system performance may affect GitLab's overall performance, we do not recommend using EFS for storage. See the relevant documentation for more details.

For Omnibus GitLab packages:

Edit /etc/gitlab/gitlab.rb:

gitlab_rails['backup_upload_connection'] = {
  :provider => 'Local',
  :local_root => '/mnt/backups'
}

# The directory inside the mounted folder to copy backups to
# Use '.' to store them in the root directory
gitlab_rails['backup_upload_remote_directory'] = 'gitlab_backups'

Reconfigure GitLab for the changes to take effect.

For installations from source:

Edit home/git/gitlab/config/gitlab.yml:

backup:
  upload:
    # Fog storage connection settings, see http://fog.io/storage/ .
    connection:
      provider: Local
      local_root: '/mnt/backups'
    # The directory inside the mounted folder to copy backups to
    # Use '.' to store them in the root directory
    remote_directory: 'gitlab_backups'

Restart GitLab for the changes to take effect.

Backup archive permissions

The backup archives created by GitLab (1393513186_2014_02_27_gitlab_backup.tar) will have owner/group git:git and 0600 permissions by default. This is meant to avoid other system users reading GitLab's data. If you need the backup archives to have different permissions you can use the 'archive_permissions' setting.

For Omnibus GitLab packages:

Edit /etc/gitlab/gitlab.rb:

gitlab_rails['backup_archive_permissions'] = 0644 # Makes the backup archives world-readable

Reconfigure GitLab for the changes to take effect.

For installations from source:

Edit /home/git/gitlab/config/gitlab.yml:

backup:
  archive_permissions: 0644 # Makes the backup archives world-readable

Restart GitLab for the changes to take effect.

Configuring cron to make daily backups

NOTE: Note: The following cron jobs do not backup your GitLab configuration files or SSH host keys.

For Omnibus GitLab packages:

Edit /etc/gitlab/gitlab.rb:

## Limit backup lifetime to 7 days - 604800 seconds
gitlab_rails['backup_keep_time'] = 604800

Reconfigure GitLab for the changes to take effect.

Note that the backup_keep_time configuration option only manages local files. GitLab does not automatically prune old files stored in a third-party object storage (e.g., AWS S3) because the user may not have permission to list and delete files. We recommend that you configure the appropriate retention policy for your object storage. For example, you can configure the S3 backup policy as described here.

To schedule a cron job that backs up your repositories and GitLab metadata, use the root user:

sudo su -
crontab -e

There, add the following line to schedule the backup for everyday at 2 AM:

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

You may also want to set a limited lifetime for backups to prevent regular backups using all your disk space.

For installations from source:

Edit home/git/gitlab/config/gitlab.yml:

backup:
  ## Limit backup lifetime to 7 days - 604800 seconds
  keep_time: 604800

Restart GitLab for the changes to take effect.

sudo -u git crontab -e # Edit the crontab for the git user

Add the following lines at the bottom:

# Create a full backup of the GitLab repositories and SQL database every day at 4am
0 4 * * * cd /home/git/gitlab && PATH=/usr/local/bin:/usr/bin:/bin bundle exec rake gitlab:backup:create RAILS_ENV=production CRON=1

The CRON=1 environment setting tells the backup script to suppress all progress output if there are no errors. This is recommended to reduce cron spam.

Restore

GitLab provides a simple command line interface to restore your whole installation, and is flexible enough to fit your needs.

The restore prerequisites section includes crucial information. Make sure to read and test the whole restore process at least once before attempting to perform it in a production environment.

You can only restore a backup to exactly the same version and type (CE/EE) of GitLab that you created it on, for example CE 9.1.0.

Restore prerequisites

You need to have a working GitLab installation before you can perform a restore. This is mainly because the system user performing the restore actions ('git') is usually not allowed to create or delete the SQL database it needs to import data into ('gitlabhq_production'). All existing data will be either erased (SQL) or moved to a separate directory (repositories, uploads).

To restore a backup, you will also need to restore /etc/gitlab/gitlab-secrets.json (for Omnibus packages) or /home/git/gitlab/.secret (for installations from source). This file contains the database encryption key, CI/CD variables, and variables used for two-factor authentication. If you fail to restore this encryption key file along with the application data backup, users with two-factor authentication enabled and GitLab Runners will lose access to your GitLab server.

You may also want to restore any TLS keys, certificates, or SSH host keys.

Depending on your case, you might want to run the restore command with one or more of the following options:

BACKUP=timestamp_of_backup - Required if more than one backup exists. Read what the backup timestamp is about.
force=yes - Does not ask if the authorized_keys file should get regenerated and assumes 'yes' for warning that database tables will be removed, enabling the "Write to authorized_keys file" setting, and updating LDAP providers.

If you are restoring into directories that are mountpoints you will need to make sure these directories are empty before attempting a restore. Otherwise GitLab will attempt to move these directories before restoring the new data and this would cause an error.

Restore for installation from source

# Stop processes that are connected to the database
sudo service gitlab stop

bundle exec rake gitlab:backup:restore RAILS_ENV=production

Next, restore /home/git/gitlab/.secret if necessary as mentioned above.

Restart GitLab:

sudo service gitlab restart

Restore for Omnibus GitLab installations

This procedure assumes that:

You have installed the exact same version and type (CE/EE) of GitLab Omnibus with which the backup was created.
You have run sudo gitlab-ctl reconfigure at least once.
GitLab is running. If not, start it using sudo gitlab-ctl start.

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.

sudo cp 11493107454_2018_04_25_10.6.4-ce_gitlab_backup.tar /var/opt/gitlab/backups/
sudo 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:

sudo gitlab-ctl stop unicorn
sudo gitlab-ctl stop sidekiq
# Verify
sudo 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!
sudo gitlab-rake gitlab:backup:restore BACKUP=1493107454_2018_04_25_10.6.4-ce

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

Restart and check GitLab:

sudo gitlab-ctl restart
sudo 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.

Restore for Docker image and GitLab helm chart installations

For GitLab installations using the Docker image or the GitLab helm chart on a Kubernetes cluster, the restore task expects the restore directories to be empty. However, with docker and Kubernetes volume mounts, some system level directories may be created at the volume roots, like lost+found directory found in Linux operating systems. These directories are usually owned by root, which can cause access permission errors since the restore rake task runs as git user. So, to restore a GitLab installation, users have to confirm the restore target directories are empty.

For both these installation types, the backup tarball has to be available in the backup location (default location is /var/opt/gitlab/backups).

For docker installations, the restore task can be run from host:

docker exec -it <name of container> gitlab-rake gitlab:backup:restore

The GitLab helm chart uses a different process, documented in restoring a GitLab helm chart installation.

Alternative backup strategies

If your GitLab server contains a lot of Git repository data you may find the GitLab backup script to be too slow. In this case you can consider using filesystem snapshots as part of your backup strategy.

Example: Amazon EBS

A GitLab server using omnibus-gitlab hosted on Amazon AWS. An EBS drive containing an ext4 filesystem is mounted at /var/opt/gitlab. In this case you could make an application backup by taking an EBS snapshot. The backup includes all repositories, uploads and Postgres data.

Example: LVM snapshots + rsync

A GitLab server using omnibus-gitlab, with an LVM logical volume mounted at /var/opt/gitlab. Replicating the /var/opt/gitlab directory using rsync would not be reliable because too many files would change while rsync is running. Instead of rsync-ing /var/opt/gitlab, we create a temporary LVM snapshot, which we mount as a read-only filesystem at /mnt/gitlab_backup. Now we can have a longer running rsync job which will create a consistent replica on the remote server. The replica includes all repositories, uploads and Postgres data.

If you are running GitLab on a virtualized server you can possibly also create VM snapshots of the entire GitLab server. It is not uncommon however for a VM snapshot to require you to power down the server, so this approach is probably of limited practical use.

Additional notes

This documentation is for GitLab Community and Enterprise Edition. We backup GitLab.com and make sure your data is secure, but you can't use these methods to export / backup your data yourself from GitLab.com.

Issues are stored in the database. They can't be stored in Git itself.

To migrate your repositories from one server to another with an up-to-date version of GitLab, you can use the import rake task to do a mass import of the repository. Note that if you do an import rake task, rather than a backup restore, you will have all your repositories, but not any other data.

Troubleshooting

Restoring database backup using omnibus packages outputs warnings

If you are using backup restore procedures you might encounter the following warnings:

psql:/var/opt/gitlab/backups/db/database.sql:22: ERROR:  must be owner of extension plpgsql
psql:/var/opt/gitlab/backups/db/database.sql:2931: WARNING:  no privileges could be revoked for "public" (two occurrences)
psql:/var/opt/gitlab/backups/db/database.sql:2933: WARNING:  no privileges were granted for "public" (two occurrences)

Be advised that, backup is successfully restored in spite of these warnings.

The rake task runs this as the gitlab user which does not have the superuser access to the database. When restore is initiated it will also run as gitlab user but it will also try to alter the objects it does not have access to. Those objects have no influence on the database backup/restore but they give this annoying warning.

For more information see similar questions on postgresql issue trackerhere and here as well as stack overflow.

When the secrets file is lost

If you have failed to back up the secrets file, then users with 2FA enabled will not be able to log into GitLab. In that case, you need to disable 2FA for everyone.

The secrets file is also responsible for storing the encryption key for several columns containing sensitive information. If the key is lost, GitLab will be unable to decrypt those columns. This will break a wide range of functionality, including (but not restricted to):

In the case of CI/CD, variables, you might experience some weird behavior, like stuck jobs or 500 errors. In that case, you can try removing contents of the ci_group_variables and ci_project_variables tables from the database.

CAUTION: Warning: Use the following commands at your own risk, and make sure you've taken a backup beforehand.

Enter the Rails console:

For Omnibus GitLab packages:

sudo gitlab-rails dbconsole

For installations from source:

sudo -u git -H bundle exec rails dbconsole RAILS_ENV=production

Check the ci_group_variables and ci_variables tables:
```
SELECT * FROM public."ci_group_variables";
SELECT * FROM public."ci_variables";
```
Those are the variables that you need to delete.

Drop the table:

DELETE FROM ci_group_variables;
DELETE FROM ci_variables;

You may need to reconfigure or restart GitLab for the changes to take effect.

You should now be able to visit your project, and the jobs will start running again.

A similar strategy can be employed for the remaining features - by removing the data that cannot be decrypted, GitLab can be brought back into working order, and the lost data can be manually replaced.
