# Repository Mirror
|
||
|
||
Repository mirroring allows for the mirroring of repositories to and from external sources. You can use it to mirror branches, tags, and commits between repositories.

||
## Use cases
|
||
|
||
The following are some possible use cases for repository mirroring:
|
||
|
||
- You migrated to Gitea but still need to keep your project in another source. In that case, you can simply set it up to mirror to Gitea (pull) and all the essential history of commits, tags, and branches are available in your Gitea instance.
|
||
- You have old projects in another source that you don’t use actively anymore, but don’t want to remove for archiving purposes. In that case, you can create a push mirror so that your active Gitea repository can push its changes to the old location.
|
||
|
||
## Pulling from a remote repository
|
||
|
||
For an existing remote repository, you can set up pull mirroring as follows:
|
||
|
||
1. Select **New Migration** in the **Create...** menu on the top right.
|
||
2. Select the remote repository service.
|
||
3. Enter a repository URL.
|
||
4. If the repository needs authentication fill in your authentication information.
|
||
5. Check the box **This repository will be a mirror**.
|
||
6. Select **Migrate repository** to save the configuration.
|
||
|
||
The repository now gets mirrored periodically from the remote repository. You can force a sync by selecting **Synchronize Now** in the repository settings.
|
||
|
||
## Pushing to a remote repository
|
||
|
||
For an existing repository, you can set up push mirroring as follows:
|
||
|
||
1. In your repository, go to **Settings** > **Repository**, and then the **Mirror Settings** section.
|
||
2. Enter a repository URL.
|
||
3. If the repository needs authentication expand the **Authorization** section and fill in your authentication information.
|
||
4. Select **Add Push Mirror** to save the configuration.
|
||
|
||
The repository now gets mirrored periodically to the remote repository. You can force a sync by selecting **Synchronize Now**. In case of an error a message displayed to help you resolve it.
|
||
|
||
:exclamation::exclamation: **NOTE:** This will force push to the remote repository. This will overwrite any changes in the remote repository! :exclamation::exclamation:
