He estado usando deja dup como copia de seguridad durante años en esta misma computadora. Recientemente actualicé mis discos duros externos que uso para realizar copias de seguridad, pero comencé a realizar copias de seguridad incrementales con éxito. Después de aproximadamente un mes de realizar copias de seguridad, parece que toda la copia de seguridad (años de duración) está rota. Solicita repetidamente la contraseña al intentar realizar una copia de seguridad o restaurar y no llega a ninguna parte. Aquí está el resultado que obtengo cuando configuro DEJA_DUP_DEBUG=1

¿Mi única opción es simplemente iniciar las copias de seguridad de nuevo? Siento que esto es inaceptable ya que si es posible que esto vuelva a suceder, no podré restaurar nada. Sé que mi frase de contraseña es correcta, ya que nunca se cambió y está almacenada tanto en mi memoria como en mi llavero (y la he ingresado manualmente muchas veces sin éxito). ¿Es su solución de respaldo más confiable que la duplicidad? ¿Estoy perdiendo el tiempo cifrando mis copias de seguridad? Gracias por tu ayuda, estoy bastante frustrado.
ACTUALIZACIÓN: Acabo de iniciar una nueva copia de seguridad desde cero. Oh bien.
