How to backup database only (without uploads) from console?

Is there a way to backup database only from console?

./launcher enter app
discourse backup

fails while trying to include uploads:

Yes, you can take db only backup from rails console with below commands.

./launcher enter app
rails c
> BackupRestore::Backuper.new(Discourse.system_user.id, with_uploads: false)

Hmm, this didn’t produce the backup file. Manual backup works as expected though.

Are there any logs I should examine?

Command output:

Ah, I forgot to add .run in the end. It should be BackupRestore::Backuper.new(Discourse.system_user.id, with_uploads: false).run

I got interested in the subject and read a lot of threads. My conclusion is that it is even safe to restore copies straight from the console to avoid bugs - generally how to do it correctly ?
