# Pushing an image to an Amazon ECR private repository
<a name="image-push"></a>

You can push your Docker images, manifest lists, and Open Container Initiative (OCI) images and compatible artifacts to your private repositories.

Amazon ECR provides a way to replicate your images to other repositories. By specifying a replication configuration in your private registry settings, you can replicate across Regions in your own registry and across different accounts. For more information, see [Private registry settings in Amazon ECR](registry-settings.md).

**Note**  
If you push an image that is currently archived, that image will be automatically restored and removed from the archive. For more information about archiving and restoring images, see [Archiving an image in Amazon ECR](archive_restore_image.md).

When registry blob mounting is enabled and mounting parameters are included, Amazon ECR automatically checks for existing layers in your registry during push operations. If a layer already exists in another repository within the same registry, Amazon ECR will mount the existing layer instead of uploading a duplicate. For more information, see [Blob mounting in Amazon ECR](blob-mounting.md).
