-> If you don't configure {% data variables.product.prodname_registry %} on the staging instance before restoring your production backup, your staging instance will use your production instance's external storage, which could result in loss of data. We strongly recommended that you use different external storage for your staging instance.
-
-1. Review the backup you will restore to the staging instance.
-   * If you took the backup with {% data variables.product.prodname_enterprise_backup_utilities %} 3.5 or later, the backup includes the configuration for {% data variables.product.prodname_registry %}. Continue to the next step.
-   * If you took the backup with {% data variables.product.prodname_enterprise_backup_utilities %} 3.4 or earlier, configure {% data variables.product.prodname_registry %} on the staging instance. For more information, see [AUTOTITLE](/admin/packages/getting-started-with-github-packages-for-your-enterprise).

-     ghe-config secrets.packages.azure-container-name "AZURE CONTAINER NAME"
-     ghe-config secrets.packages.azure-connection-string "CONNECTION STRING"
