Einrichtung des Hochladens von Dateien und Bildern zu S3

The linked thread mentions a PR to remove a migrate_from_s3 task, and I have seen no reason to believe it has been added back later, but I wanted to check if this was still the case. I am considering migrating to MinIO and am a bit concerned with making it a dependency.

I wonder if this could provide a workaround for what I mentioned above. Include that setting, make a backup, disable S3 settings, and restore the backup.
