[deprecated] I18n.enforce_available_locales
just FYI
gitlab-rake gitlab:backup:create > /dev/null
[deprecated] I18n.enforce_available_locales will default to true in the future. If you really want to skip validation of your locale you can set I18n.enforce_available_locales = false to avoid this message.
