## Backups
[See our backup strategy](https://about.gitlab.com/handbook/engineering/infrastructure/production/#backups).
There are several ways to perform backups of your content on GitLab.com.
To back up an entire project on GitLab.com, you can export it either:
Projects can be backed up in their entirety by exporting them either [through the UI](../project/settings/import_export.md) or [API](../../api/project_import_export.md#schedule-an-export), the latter of which can be used to programmatically upload exports to a storage platform such as AWS S3.
- [Through the UI](../project/settings/import_export.md).
- [Through the API](../../api/project_import_export.md#schedule-an-export). You
can also use the API to programmatically upload exports to a storage platform,
such as Amazon S3.
With exports, be sure to take note of [what is and is not](../project/settings/import_export.md#exported-contents), included in a project export.
With exports, be aware of [what is and is not](../project/settings/import_export.md#exported-contents)
included in a project export.
Since GitLab is built on Git, you can back up **just** the repository of a project by [cloning](../../gitlab-basics/start-using-git.md#clone-a-repository) it to another machine. Similarly, if you need to back up just the wiki of a repository it can also be cloned and all files uploaded to that wiki are included [if they were uploaded after 2020-08-22](../project/wiki/index.md#create-a-new-wiki-page).
