 Superset uses [Scarf](https://about.scarf.sh/) by default to collect basic telemetry data upon installing and/or running Superset. This data helps the maintainers of Superset better understand which versions of Superset are being used, in order to prioritize patch/minor releases and security fixes.
 We use the [Scarf Gateway](https://docs.scarf.sh/gateway/) to sit in front of container registries, and the [scarf-js](https://about.scarf.sh/package-sdks) package to track `npm` installations.
 Scarf purges PII and provides aggregated statistics. Superset users can easily opt out of analytics in various ways documented [here](https://docs.scarf.sh/gateway/#do-not-track) and [here](https://docs.scarf.sh/package-analytics/#as-a-user-of-a-package-using-scarf-js-how-can-i-opt-out-of-analytics). Additional opt-out instructions for Docker users are available on the [Docker Installation](https://superset.apache.org/docs/installation/installing-superset-using-docker-compose) page.

+### Does Superset have an archive panel or trash bin from which a user can recover deleted assets?
+
+No. Currently, there is no way to recover a deleted Superset dashboard/chart/dataset/database from the UI. However, there is an [ongoing discussion](https://github.com/apache/superset/discussions/18386) about implementing such a feature.
+
+Hence, it is recommended to take periodic backups of the metadata database. For recovery, you can launch a recovery instance of a Superset server with the backed-up copy of the DB attached and use the Export Dashboard button in the Superset UI (or the `superset export-dashboards` CLI command). Then, take the .zip file and import it into the current Superset instance.
+
+Alternatively, you can programmatically take regular exports of the assets as a backup.
