dbbackup with django/docker/celery/celery-beat not working: no error but no file stored?

Bug Report

Try to implement a periodic postgresql database backup using django/docker/celelry/celery-beat but can not find my file

Describe the bug

I can create 'manually' a dbbackup file using python manage.py dbbackup and can recover the backup file default-PRT-063-2020-12-29-174901.dump in backup folder as specified in settings

but when I try to use celery and call_command('dbbackup'), seems to works as I have no error (see below)
but I could not find the file anywhere (locally or in my docker container)

I notice that file extension is not the same .dump (manually) and .psql (call_command)

below are trace and all seems to be OK

celery_1 | Backing Up Database: db_dev

If you have a separate container for your celery workers, the backup files are most likely being dumped in there.
