Restore GitLab
GitLab provides a command line interface to restore your entire installation, and is flexible enough to fit your needs.
The restore prerequisites section includes crucial information. Be sure to read and test the complete restore process at least once before attempting to perform it in a production environment.
You can restore a backup only to the exact same version and type (CE/EE) of GitLab that you created it on (for example CE 9.1.0).
If your backup is a different version than the current installation, you must downgrade your GitLab installation before restoring the backup.
Restore prerequisites
You need to have a working GitLab installation before you can perform a
restore. This is because the system user performing the restore actions (git
)
is usually not allowed to create or delete the SQL database needed to import
data into (gitlabhq_production
). All existing data is either erased
(SQL) or moved to a separate directory (such as repositories and uploads).
To restore a backup, you must 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 Runner
loses access to your GitLab server.
You may also want to restore your previous /etc/gitlab/gitlab.rb
(for Omnibus packages)
or /home/git/gitlab/config/gitlab.yml
(for installations from source) and
any TLS keys, certificates (/etc/gitlab/ssl
, /etc/gitlab/trusted-certs
), or
SSH host keys.
Starting with GitLab 12.9, if an untarred backup (like the ones made with
SKIP=tar
) is found, and no backup is chosen with BACKUP=<timestamp>
, the
untarred backup is used.
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
: Doesn't ask if theauthorized_keys
file should get regenerated, and assumes 'yes' for warning about database tables being removed, enabling theWrite to authorized_keys file
setting, and updating LDAP providers.
If you're restoring into directories that are mount points, you must ensure these directories are empty before attempting a restore. Otherwise, GitLab attempts to move these directories before restoring the new data, which causes an error.

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 ensure 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
. The backup file 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 puma
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-backup restore BACKUP=11493107454_2018_04_25_10.6.4-ce
Users of GitLab 12.1 and earlier should use the command gitlab-rake gitlab:backup:restore
instead.
Some known non-blocking error messages may appear.
WARNING:
gitlab-rake gitlab:backup:restore
doesn't set the correct file system
permissions on your Registry directory. This is a known issue.
In GitLab 12.2 or later, you can use gitlab-backup restore
to avoid this
issue.
If there's a GitLab version mismatch between your backup tar file and the installed version of GitLab, the restore command aborts with an error message. Install the correct GitLab version, and then try again.
WARNING: The restore command requires additional parameters when your installation is using PgBouncer, for either performance reasons or when using it with a Patroni cluster.
Next, restore /etc/gitlab/gitlab-secrets.json
if necessary,
as previously mentioned.
Reconfigure, restart and check GitLab:
sudo gitlab-ctl reconfigure
sudo gitlab-ctl restart
sudo gitlab-rake gitlab:check SANITIZE=true
In GitLab 13.1 and later, check database values can be decrypted
especially if /etc/gitlab/gitlab-secrets.json
was restored, or if a different server is
the target for the restore.
sudo gitlab-rake gitlab:doctor:secrets
For added assurance, you can perform an integrity check on the uploaded files:
sudo gitlab-rake gitlab:artifacts:check
sudo gitlab-rake gitlab:lfs:check
sudo gitlab-rake gitlab:uploads:check
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, such as the 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 the git
user. 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:
# Stop the processes that are connected to the database
docker exec -it <name of container> gitlab-ctl stop puma
docker exec -it <name of container> gitlab-ctl stop sidekiq
# Verify that the processes are all down before continuing
docker exec -it <name of container> gitlab-ctl status
# Run the restore. NOTE: "_gitlab_backup.tar" is omitted from the name
docker exec -it <name of container> gitlab-backup restore BACKUP=11493107454_2018_04_25_10.6.4-ce
# Restart the GitLab container
docker restart <name of container>
# Check GitLab
docker exec -it <name of container> gitlab-rake gitlab:check SANITIZE=true
Users of GitLab 12.1 and earlier should use the command gitlab-rake gitlab:backup:create
instead.
WARNING:
gitlab-rake gitlab:backup:restore
doesn't set the correct file system
permissions on your Registry directory. This is a known issue.
In GitLab 12.2 or later, you can use gitlab-backup restore
to avoid this
issue.
The GitLab Helm chart uses a different process, documented in restoring a GitLab Helm chart installation.
Restore for installation from source
First, ensure your backup tar file is in the backup directory described in the
gitlab.yml
configuration:
## Backup settings
backup:
path: "tmp/backups" # Relative paths are relative to Rails.root (default: tmp/backups/)
The default is /home/git/gitlab/tmp/backups
, and it needs to be owned by the git
user. Now, you can begin the backup procedure:
# Stop processes that are connected to the database
sudo service gitlab stop
sudo -u git -H bundle exec rake gitlab:backup:restore RAILS_ENV=production

Restoring only one or a few projects or groups from a backup
Although the Rake task used to restore a GitLab instance doesn't support restoring a single project or group, you can use a workaround by restoring your backup to a separate, temporary GitLab instance, and then export your project or group from there:
- Install a new GitLab instance at the same version as the backed-up instance from which you want to restore.
- Restore the backup into this new instance, then export your project or group. Be sure to read the Important Notes on either export feature's documentation to understand what is and isn't exported.
- After the export is complete, go to the old instance and then import it.
- After importing the projects or groups that you wanted is complete, you may delete the new, temporary GitLab instance.
A feature request to provide direct restore of individual projects or groups is being discussed in issue #17517.
Restore options
The command line tool GitLab provides to restore from backup can accept more options.
Disabling prompts during restore
During a restore from backup, the restore script may ask for confirmation before
proceeding. If you wish to disable these prompts, you can set the GITLAB_ASSUME_YES
environment variable to 1
.
For Omnibus GitLab packages:
sudo GITLAB_ASSUME_YES=1 gitlab-backup restore
For installations from source:
sudo -u git -H GITLAB_ASSUME_YES=1 bundle exec rake gitlab:backup:restore RAILS_ENV=production
Excluding tasks on restore
Introduced in GitLab 14.10.
You can exclude specific tasks on restore by adding the environment variable SKIP
, whose values are a comma-separated list of the following options:
-
db
(database) -
uploads
(attachments) -
builds
(CI job output logs) -
artifacts
(CI job artifacts) -
lfs
(LFS objects) -
terraform_state
(Terraform states) -
registry
(Container Registry images) -
pages
(Pages content) -
repositories
(Git repositories data) -
packages
(Packages)
For Omnibus GitLab packages:
sudo gitlab-backup restore BACKUP=timestamp_of_backup SKIP=db,uploads
For installations from source:
sudo -u git -H bundle exec rake gitlab:backup:restore BACKUP=timestamp_of_backup SKIP=db,uploads RAILS_ENV=production
Restore specific repository storages
Introduced in GitLab 15.0.
When using multiple repository storages,
repositories from specific repository storages can be restored separately
using the REPOSITORIES_STORAGES
option. The option accepts a comma-separated list of
storage names.
For example, for Omnibus GitLab installations:
sudo gitlab-backup restore BACKUP=timestamp_of_backup REPOSITORIES_STORAGES=storage1,storage2
For example, for installations from source:
sudo -u git -H bundle exec rake gitlab:backup:restore BACKUP=timestamp_of_backup REPOSITORIES_STORAGES=storage1,storage2
Restore specific repositories
Introduced in GitLab 15.1.
You can restore specific repositories using the REPOSITORIES_PATHS
option.
The option accepts a comma-separated list of project and group paths. If you
specify a group path, all repositories in all projects in the group and
descendent groups are included. The project and group repositories must exist
within the specified backup.
For example, to restore all repositories for all projects in Group A (group-a
), and the repository for Project C in Group B (group-b/project-c
):
-
Omnibus GitLab installations:
sudo gitlab-backup restore BACKUP=timestamp_of_backup REPOSITORIES_PATHS=group-a,group-b/project-c
-
Installations from source:
sudo -u git -H bundle exec rake gitlab:backup:restore BACKUP=timestamp_of_backup REPOSITORIES_PATHS=group-a,group-b/project-c
