Situation réelle de la question

J'essaie de créer une image disque compressée d'une sauvegarde Time Machine (qui est stockée sur un disque dur externe) sur Yosemite.

hdiutil échoue au premier lien symbolique qu'il rencontre. Avant l'échec, il y a également une erreur d'authentification suivie d'une invite de mot de passe de l'interface graphique. Si je refuse l'authentification, il se produit ce qui suit :

hdiutil create -srcfolder `tmutil latestbackup` -ov -verbose -o backup.dmg

CodeResources est le premier lien symbolique que le processus rencontre.

0: group:everyone deny write,delete,append,writeattr,writeextattr,chown

J'ai trouvé le même problème discuté aquí mais ils ne parviennent jamais à déterminer quel est le problème du lien symbolique qui fait échouer copy-helper.

Pourquoi les hdiutil demande les droits de propriété, et pourquoi échoue-t-il sur ce lien symbolique ?

J'ai rencontré le même problème en essayant la même chose sur Mojave. Il semble que les ACL sur les liens symboliques ne soient pas pris en charge lorsque l'on travaille dans les limites des images de disque. J'ai cependant trouvé une solution de contournement :

  1. Créez une image vide suffisamment grande pour contenir la sauvegarde.

  2. ditto le répertoire de sauvegarde dans l'image sparse montée. Il émettra la même plainte sur le fait que l'opération n'est pas prise en charge sur ces liens symboliques, mais il le copiera quand même et traitera cette erreur comme un simple avertissement et continuera.

  3. Une fois l'opération terminée, démontez l'image éparse et utilisez l'Utilitaire de disque pour la convertir en une image compressée.
