Se mejoró lo siguiente: - se añadió "set -euo pipefail" para asegurar que el script falle en cuanto algo no funcione - se creara un registro log en /var/log/backup.log - se utiliza el UUID en el mount del disco para evitar errores de montaje - se agrego "mkdir -p" en la creación de carpetas para evita problemas si faltan directorios padres. - se añadió umount -l "$backup_path" para evitar errores si el disco está ocupado
