For creating a backup, the following steps need to be performed:

1. In the database management screen, click on the Backup Database link next to the database you want to back up:

2. Fill in the form:
   • Master Password: This is the master password of the Odoo server.
   • Backup Format: Always use zip for a production database, as it is the only real full backup format. Only use the pg_dump format for a development database when you don't really care about the file store.

3. Click on the Backup button. The backup file will then be downloaded to your browser.
