Hello, @papahausa . Could you please temporarily enable Plesk debug mode, reproduce the issue, and let us know what's logged under /var/log/plesk/PMM/ backup-<YYYY-MM-DD-hh-mm-ss-nnn> /backup.log? Thank you in advance.

Thank you. Unfortunately, I cannot see any specific warnings or errors in the log file in order to attempt to identify the reason for the issue. Could you please execute the following command on the server:

ls -la /var/lib/psa/dumps/.discovered/backup_info_2505120206_2505130206

Thank you. Does the issue happen only for scheduled backups, please? If you attempt to manually create a backup does it also return the same warning? Could you also execute:

crontab -e
