**Currently, dumps consist of the following Metabase artifacts:**

- Collections
- Collections (except for personal collections)
- Dashboards
- Saved questions
- Segments and Metrics defined in the Data Model
- Public sharing settings for questions and dashboards

- Admin Panel settings, except for permissions
- Database connection settings
- Data Model settings

- Permission settings
- User accounts or settings
- Alerts on saved questions
- Personal Collections or their contents (except for the user specified with the `--user` flag; see below)
- Archived items
