Overrides the default backup method of Odoo and adds the Content-Length header in the backup response.

Add this module to server_wide_modules.

## Further Explanation

WITHOUT backup_size_header: You go to the database manager, take a backup of a large database, the worker times out. You end up with a broken backup file, but you don't know that, because your browser doesn't know how large the file is supposed to be. You might get the sense that everything went fine and you have a full backup.

WITH backup_size_header: You take a backup, Odoo sends the Content-Length HTTP header to your browser, so your browser knows how large file it expects to receive. Odoo times out, and your browser tells you that the download failed. You don't have the false sense of having successfully downloaded the backup file.
