Fore some reason it is not possible to backup Minio app to another Minio app.
The backup/update process starts then stalls and eventually, after 4 hours, it crashes and spits out the error message below.

(Hovering hover this app tells me that it is making a backup.)

Even if I change backup to local filesystem the Minio app won't be backed up nor updated.
I started an update yesterday at ~1245 and today at 07:30 it is still "updating".

How can I debug this? Which logs should I parse? How do I stop a backup job?
