Me gustaría utilizar Borg Backup como solución de copia de seguridad (copia de seguridad en un servidor remoto). Borg ofrece un script sh muy conveniente que, según dicen, se puede ejecutar como un trabajo cron.

Ejecuto Debian Bullseye.

¿Cómo puedo hacer que se ejecute en cron?

AquíEs una descripción similar del problema, sin embargo, mi repositorio está cifrado.
