 # Set a retention policy for untagged manifests
 
-Azure Container Registry gives you the option to set a *retention policy* for stored image manifests that don't have any associated tags (*untagged manifests*). When a retention policy is enabled, untagged manifests in the registry are automatically deleted after a number of days you set. This feature prevents the registry from filling up with artifacts that aren't needed and helps you save on storage costs.

+Azure Container Registry gives you the option to set a *retention policy* for stored image manifests that don't have any associated tags (*untagged manifests*). When a retention policy is enabled, untagged manifests in the registry are automatically deleted after a number of days you set. This feature prevents the registry from filling up with artifacts that aren't needed and helps you save on storage costs. If  the `delete-enabled` attribute of an untagged manifest is set to `false`, the manifest can't be deleted, and the retention policy doesn't apply.
 
 You can use the Azure Cloud Shell or a local installation of the Azure CLI to run the command examples in this article. If you'd like to use it locally, version 2.0.74 or later is required. Run `az --version` to find the version. If you need to install or upgrade, see [Install Azure CLI][azure-cli].

 By default, no retention policy is set in a container registry. To set or update a retention policy, run the [az acr config retention update][az-acr-config-retention-update] command in the Azure CLI. You can specify a number of days between 0 and 365 to retain the untagged manifests. If you don't specify a number of days, the command sets a default of 7 days. After the retention period, all untagged manifests in the registry are automatically deleted.
 
-The retention policy doesn't apply to any untagged manifest that has the `delete-enabled` attribute set to `false`, or the `write-enabled` attribute set to `true`. For information about locked images and manifests, see [Lock a container image in an Azure container registry](container-registry-image-lock.md).
