Is there anything in mediacenter_backup currently? What does ll /mnt/ext/Backup/mediacenter_backup show?
Sonarr is running as your user? What does ps aux | grep sonarr show?

Is /mnt/ext/Backup an physical drive attached to that host or a network share? If a network share, NFS or SMB?

Thank you for your reply.
But the “ll” return was posted in the image, all with 777 permissions for testing, even so, it was unsuccessful.

However, on 03/20, I received a message that the update occurred automatically and successfully through my bot that monitors Telegram.
