Backup KO sous Mojave

Bonjour,

Je n'arrive plus à faire de sauvegarde avec Time Machine. La sauvegarde se plante avant même de commencer.

Voici l'erreur rencontrée après avoir passer la commande :

log show --predicate 'subsystem == "com.apple.TimeMachine"' --info --last 48h | grep Error

log show --predicate 'subsystem == "com.apple.TimeMachine"' --info --last 48h | grep Error

Avez vous une idée du problème ? J'ai fait une réparation du disque mais la sauvegarde plante toujours avant même de commencer.

Merci pour votre réponse
