Tengo un script de shell de copia de seguridad simple que se ejecuta diariamente a la 1:00 AM. Utiliza rsync para copiar doce directorios diferentes en el disco duro externo de mi computadora con Windows. Aquí hay un ejemplo:
rsync -a --delete-after --progress --stats "$HOME/Downloads" "/Volumes/Backups/MacBook Pro"
Solía funcionar bien, pero un día el kernel entró en pánico. Luego al día siguiente. Y luego el siguiente. Hice algunos problemas y descubrí que el pánico del kernel solo se produce cuando el directorio "$ HOME / Documents" está incluido en la lista de directorios de los que se realizará una copia de seguridad. Pero esto es lo extraño: si ejecuto el script de copia de seguridad manualmente, el script lo hace completamente sin un pánico en el kernel. ¿Algunas ideas? Aquí está el informe:
