28 Site Backup/Restore

The Site Backup/Restore adds Site Backup and Site Restore panels to the
site admin sidebar, allowing superusers to:

Download compressed backups of the PostgreSQL database and media folder directly to their browser (no files stored on the server).

Upload previously downloaded backups to restore the site — with
  automatic rollback if anything goes wrong. Read the instructions and warnings carefully before you perform a site restore, as this action will completely overwrite the current site.
