+# Get started administering GitLab **(FREE)**
+
+Get started with GitLab administration. Configure your organization and its authentication, then secure, monitor,
+and back up GitLab.
+
+## Authentication
+
+Authentication is the first step in making your installation secure.
+
+- [Enforce two-factor authentication (2FA) for all users](../security/two_factor_authentication.md). We highly recommended 2FA for self-managed instances.
+- Ensure users do the following:
+  - Choose a strong, secure password. If possible, store it in a password management system.
+  - If it is not configured for everyone, enable [two-factor authentication (2FA)](../user/profile/account/two_factor_authentication.md) for your account.
+    This one-time secret code is an additional safeguard that keeps intruders out, even if they have your password.
+  - Add a backup email. If you lose access to your account, the GitLab Support team can help you more quickly.
+  - Save or print your recovery codes. If you can't access your authentication device, you can use these recovery codes to sign in to your GitLab account.
+  - Add [an SSH key](../ssh/index.md) to your profile. You can generate new recovery codes as needed with SSH.
+  - Enable [personal access tokens](../user/profile/personal_access_tokens.md). When using 2FA, you can use these tokens to access the GitLab API.
+
+## Projects and groups
+
+Organize your environment by configuring your groups and projects.
+
+- [Projects](../user/project/working_with_projects.md): Designate a home for your files and code or track and organize issues in a business category.
+- [Groups](../user/group/index.md): Organize a collection of users or projects. Use these groups to quickly assign people and projects.
+- [Roles](../user/permissions.md): Define user access and visibility for your projects and groups.
+
+<i class="fa fa-youtube-play youtube" aria-hidden="true"></i>
+Watch an overview of [groups and projects](https://www.youtube.com/watch?v=cqb2m41At6s).
+
+Get started:
+
+- Create a [project](../user/project/working_with_projects.md#create-a-project).
+- Create a [group](../user/group/index.md#create-a-group).
+- [Add members](../user/group/index.md#add-users-to-a-group) to the group.
+- Create a [subgroup](../user/group/subgroups/index.md#creating-a-subgroup).
+- [Add members](../user/group/subgroups/index.md#membership) to the subgroup.
+- Enable [external authorization control](../user/admin_area/settings/external_authorization.md#configuration).
+
+**More resources**
+
+- Learn more about [running multiple Agile teams](https://www.youtube.com/watch?v=VR2r1TJCDew).
+- Sync group memberships [by using LDAP](../administration/auth/ldap/index.md#group-sync).
+- Manage user access with inherited permissions. Use up to 20 levels of subgroups to organize both teams and projects.
+  - Learn more about [inherited permissions](../user/project/members/index.md#inherited-membership).
+  - View [nested category examples](../user/group/subgroups/index.md#overview).
+
+## Import projects
+
+You may need to import projects from external sources like GitHub, Bitbucket, or another instance of GitLab. Many external sources can be imported into GitLab.
+
+- Review the [GitLab projects documentation](../user/project/index.md#project-integrations).
+- Consider [repository mirroring](../user/project/repository/repository_mirroring.md)—an [alternative to project migrations](../ci/ci_cd_for_external_repos/index.md).
+- Check out our [migration index](../user/project/import/index.md) for documentation on common migration paths.
+- Schedule your project exports with our [import/export API](../api/project_import_export.md#schedule-an-export).
+
+### Popular project imports
+
+- [GitHub Enterprise to self-managed GitLab](../integration/github.md#enabling-github-oauth): Enabling OAuth makes it easier for developers to find and import their projects.
+- [Bitbucket Server](../user/project/import/bitbucket_server.md#limitations): There are certain data limitations.
+  For assistance with these data types, contact your GitLab account manager or GitLab Support about our professional migration services.
+
+## GitLab instance security
+
+Security is an important part of the onboarding process. Securing your instance protects your work and your organization.
+
+While this isn't an exhaustive list, following these steps gives you a solid start for securing your instance.
+
+- Use a long root password, stored in a vault.
+- Install trusted SSL certificate and establish a process for renewal and revocation.
+- [Configure SSH key restrictions](../security/ssh_keys_restrictions.md#restrict-allowed-ssh-key-technologies-and-minimum-length) per your organization's guidelines.
+- [Disable new sign-ups](../user/admin_area/settings/sign_up_restrictions.md#disable-new-sign-ups).
+- Require email confirmation.
+- Set password length limit, configure SSO or SAML user management.
+- Limit email domains if allowing sign-up.
+- Require two-factor authentication (2FA).
+- [Disable password authentication](../user/admin_area/settings/sign_in_restrictions.md#password-authentication-enabled) for Git over HTTPS.
+- Set up [email notification for unknown sign-ins](../user/admin_area/settings/sign_in_restrictions.md#email-notification-for-unknown-sign-ins).
+- Configure [user and IP rate limits](https://about.gitlab.com/blog/2020/05/20/gitlab-instance-security-best-practices/#user-and-ip-rate-limits).
+- Limit [webhooks local access](https://about.gitlab.com/blog/2020/05/20/gitlab-instance-security-best-practices/#webhooks).
+- Set [rate limits for protected paths](../user/admin_area/settings/protected_paths.md).
+
+## Monitor GitLab performance
+
+After you've established your basic setup, you're ready to review the GitLab monitoring services. Prometheus is our core performance monitoring tool.
+Unlike other monitoring solutions (for example, Zabbix or New Relic), Prometheus is tightly integrated with GitLab and has extensive community support.
+
+- [Prometheus](../administration/monitoring/prometheus/index.md) captures
+  [these GitLab metrics](../administration/monitoring/prometheus/gitlab_metrics.md#metrics-available).
+- Learn more about GitLab [bundled software metrics](../administration/monitoring/prometheus/index.md#bundled-software-metrics).
+- Prometheus and its exporters are on by default. However, you need to [configure the service](../administration/monitoring/prometheus/index.md#configuring-prometheus).
+- Learn more about [GitLab architecture](../development/architecture.md).
+- Find out why [application performance metrics](https://about.gitlab.com/blog/2020/05/07/working-with-performance-metrics/) matter.
+- Create a [self-monitoring project](../administration/monitoring/gitlab_self_monitoring_project/index.md) to track the health of your instance.
+- Integrate Grafana to [build visual dashboards](https://youtu.be/f4R7s0An1qE) based on performance metrics.
+
+### Components of monitoring
+
+- [Web servers](../administration/monitoring/prometheus/gitlab_metrics.md#puma-metrics): Handles server requests and facilitates other back-end service transactions.
+  Monitor CPU, memory, and network IO traffic to track the health of this node.
+- [Workhorse](../administration/monitoring/prometheus/gitlab_metrics.md#metrics-available): Alleviates web traffic congestion from the main server.
+  Monitor latency spikes to track the health of this node.
+- [Sidekiq](../administration/monitoring/prometheus/gitlab_metrics.md#sidekiq-metrics): Handles background operations that allow GitLab to run smoothly.
+  Monitor for long, unprocessed task queues to track the health of this node.
+
+## Back up your GitLab data
+
+GitLab provides backup methods to keep your data safe and recoverable. Whether you use a self-managed or a GitLab SaaS database, it's crucial to back up your data regularly.
+
+- Decide on a backup strategy.
+- Consider writing a cron job to make daily backups.
+- Separately backup the configuration files.
+- Decide what should be left out of the backup.
+- Decide where to upload the backups.
+- Limit backup lifetime.
+- Run a test backup and restore.
+- Set up a way to periodically verify the backups.
+
+### Back up a GitLab self-managed instance
+
+The routine differs, depending on whether you deployed with Omnibus or the Helm chart.
+
+When you backing up an Omnibus (single node) GitLab server, you can use a single Rake task.
+
+Learn about [backing up Omnibus or Helm variations](../raketasks/backup_restore.md#back-up-gitlab).
+This process backs up your entire instance, but does not back up the configuration files. Ensure those are backed up separately.
+Keep your configuration files and backup archives in a separate location to ensure the encryption keys are not kept with the encrypted data.
+
+#### Restore a backup
+
+You can restore a backup only to **the exact same version and type** (Community Edition/Enterprise Edition) of GitLab on which it was created.
+
+- Review the [Omnibus backup and restore documentation](https://docs.gitlab.com/omnibus/settings/backups).
+- Review the [Helm Chart backup and restore documentation](https://docs.gitlab.com/charts/backup-restore).
+
+### Back up GitLab SaaS
+
+Backups of GitLab databases and filesystems are taken every 24 hours, and are kept for two weeks on a rolling schedule. All backups are encrypted.
+
+- GitLab SaaS creates backups to ensure your data is secure, but you can't use these methods to export or back up your data yourself.
+- Issues are stored in the database. They can't be stored in Git itself.
+- You can use the project export option in:
+  - [The UI](../user/project/settings/import_export.md#exporting-a-project-and-its-data).
+  - [The API](../api/project_import_export.md#schedule-an-export).
+- [Group export](../user/group/settings/import_export.md) does *not* export the projects in it, but does export:
+  - Epics
+  - Milestones
+  - Boards
+  - Labels
+  - Additional items
+
+For more information about GitLab SaaS backups, see our [Backup FAQ page](https://about.gitlab.com/handbook/engineering/infrastructure/faq/#gitlabcom-backups).
+
+### Alternative backup strategies
+
+In some situations the Rake task for backups may not be the most optimal solution. Here are some
+[alternatives](../raketasks/backup_restore.md) to consider if the Rake task does not work for you.
+
+#### Option 1: File system snapshot
+
+If your GitLab server contains a lot of Git repository data, you may find the GitLab backup script to be too slow. It can be especially slow when backing up to an offsite location.
+
+Slowness typically starts at a Git repository data size of around 200 GB. In this case, you might consider using file system snapshots as part of your backup strategy.
+For example, consider a GitLab server with the following components:
+
+- Using Omnibus GitLab
+- Hosted on AWS with an EBS drive containing an ext4 file system mounted at `/var/opt/gitlab`.
+
+The EC2 instance meets the requirements for an application data backup by taking an EBS snapshot. The backup includes all repositories, uploads, and PostgreSQL data.
+
+In general, if you're running GitLab on a virtualized server, you can create VM snapshots of the entire GitLab server.
+It is common for a VM snapshot to require you to power down the server.
+
+#### Option 2: GitLab Geo
+
+Geo provides local, read-only instances of your GitLab instances.
+
+While GitLab Geo helps remote teams work more efficiently by using a local GitLab node, it can also be used as a disaster recovery solution.
+Learn more about using [Geo as a disaster recovery solution](../administration/geo/disaster_recovery/index.md).
+
+Geo replicates your database, your Git repositories, and a few other assets.
+Learn more about [replication limitations](../administration/geo/replication/datatypes.md#limitations-on-replicationverification).

+
+## API and rate limits for self-managed GitLab
+
+Rate limits prevent denial-of-service or brute-force attacks. In most cases, you can reduce the load on your application
+and infrastructure by limiting the rate of requests from a single IP address.
+
+Rate limits also improve the security of your application.
+
+### Configure rate limits for self-managed GitLab
+
+You can make changes to your default rate limits from the Admin Area. For more information about configuration, see the [Admin Area page](../security/rate_limits.md#admin-area-settings).
+
+- Define [issues rate limits](../user/admin_area/settings/rate_limit_on_issues_creation.md) to set a maximum number of issue creation requests per minute, per user.
+- Enforce [user and IP rate limits](../user/admin_area/settings/user_and_ip_rate_limits.md) for unauthenticated web requests.
+- Review the [rate limit on raw endpoints](../user/admin_area/settings/rate_limits_on_raw_endpoints.md). The default setting is 300 requests per minute for raw file access.
+- Review the [import/export rate limits](../user/admin_area/settings/import_export_rate_limits.md) of the six active defaults.
+
+For more information about API and rate limits, see our [API page](../api/index.md).
+
+## API and rate limits for GitLab SaaS
+
+Rate limits prevent denial-of-service or brute-force attacks. IP blocks usually happen when GitLab.com receives unusual traffic
+from a single IP address. The system views unusual traffic as potentially malicious based on rate limit settings.
+
+Rate limits also improve the security of your application.
+
+### Configure rate limits for GitLab SaaS
+
+You can make changes to your default rate limits from the Admin Area. For more information about configuration, see the [Admin Area page](../security/rate_limits.md#admin-area-settings).
+
+- Review the rate limit page.
+- Read our [API page](../api/index.md) for more information about API and rate limiting.
+
+### GitLab SaaS-specific block and error responses
+
+- [403 forbidden error](../user/gitlab_com/index.md#gitlabcom-specific-rate-limits): If the error occurs for all GitLab SaaS requests, look for an automated process that could have triggered a block. For more assistance, contact GitLab support with your error details, including the affected IP address.
+- [HAProxy API throttle](../user/gitlab_com/index.md#haproxy): GitLab SaaS responds with HTTP status code 429 to API requests that exceed 10 requests per second, per IP address.
+- [Protected paths throttle](../user/gitlab_com/index.md#protected-paths-throttle): GitLab SaaS responds with HTTP status code 429 to POST requests at protected paths that exceed 10 requests per minute, per IP address.
+- [Git and container registry failed authentication ban](../user/gitlab_com/index.md#git-and-container-registry-failed-authentication-ban): GitLab SaaS responds with HTTP status code 403 for one hour if it receives 30 failed authentication requests in three minutes from a single IP address.
