Eu configurei um compartilhamento Samba para backups do Time Machine de acordo comeste guia.
Meu Mac reconhece o compartilhamento corretamente, mas o backup inicial falha com a mensagem de erro genérica de que nenhum backup pôde ser criado no meu compartilhamento.
A execução log stream --style syslog --predicate 'senderImagePath contains[cd] "TimeMachine"' --infofornece o seguinte log:
MacBook-Air-2:~ xxx$ log stream --style syslog --predicate 'senderImagePath contains[cd] "TimeMachine"' --info

O estranho é que, ao contrário do log, um pacote esparso chamado 74F8F302-361C-4490-9E35-1F2598F9D16E/A76BCEEB-A3BD-5D63-82F4-8AEBB2F5ACBA.sparsebundleé criado no meu compartilhamento. Portanto, as permissões de gravação definitivamente não são o problema.

Acontece que a configuração que tentei não funciona com unidades formatadas em HFS+. Reformatar a unidade com ext4 faz com que o erro desapareça e o backup seja realmente iniciado.
