La copia de seguridad de Time Machine falla silenciosamente. El registro dice "Copia de seguridad cancelada".

1

Desde hace unos días, la mayoría de los intentos de Time Machine para hacer una copia de seguridad de mi Mac se cancelan silenciosamente. Aquí está la situación:

  • Las copias de seguridad automáticas de Time Machine están activadas.
  • La preparación de las copias de seguridad se inicia según lo programado, ya que se puede ver haciendo clic en el elemento de la barra de menú de Time Machine.
  • El procedimiento de respaldo se cancela sin previo aviso.

La última copia de seguridad exitosa ahora tiene 48 horas, aunque mi Mac ha estado en casa todo el día y tenía muchas posibilidades de hacer una copia de seguridad.

Estoy en 10.14.2. Uso un Time Capsule MB277 de 2008 o 2009 a través de WiFi. Esta es la salida de syslog relacionada con Time Machine de un intento fallido de hacer una copia de seguridad manual de mi máquina:

Las copias de seguridad de Time Machine no son compatibles con afp en Mojave, iirc. Intente eliminar el destino de la copia de seguridad y agregarlo nuevamente.

Tengo un problema con Time Machine en High Sierra. El disco que estoy copiando está formateado como APFS. Time Machine tuvo problemas con eso, me dijeron. Tal vez se ha solucionado en Mojave. No lo sé.

Intente borrar un poco de espacio en la unidad de origen que está intentando hacer una copia de seguridad.

He visto registros de Time Machine similares a este cuando Time Machine tiene problemas para organizar las cosas dentro del espacio disponible en la unidad de origen. A menudo se necesitan varios GB (no sé por qué). Entonces, si puede hacer que su unidad tenga más de 40 GB de espacio libre, hágalo.

Por cierto, usando log stream --predicate 'subsystem == "com.apple.TimeMachine"' --info --debuglíneas de etiquetas que se consideran errores un poco más claramente.
