The Ibn Sina Pharmacies' nightly backups stopped without a single alert

The Ibn Sina Pharmacies (four pharmacies in Tangier and Tetouan) manage stock and prescriptions on srv-gestion-01 (Ubuntu 24.04, MariaDB). Every night at 02:30, a cron job runs /usr/local/bin/sauvegarde-base.sh: it dumps the database into /sauvegardes, then copies it to the Tetouan NAS with rclone.

This morning, the pharmacist wanted to restore an invoice: the most recent file dates from 6 October, and the NAS has received nothing since late September. Nobody received any alert.

History: on 1 October, Yassine installed rclone and added the copy to the NAS. On 7 October, Salma re-uploaded an edited version of the script from her PC with WinSCP.

Find out why the job fails, fix it and prove it will work tonight, under cron's conditions.
