我已經根據以下內容設定了用於時間機器備份的 Samba 共享本指南。
我的 Mac 可以正確識別共享，但初始備份失敗，並顯示一般錯誤訊息：無法在我的共享上建立備份。
運行log stream --style syslog --predicate 'senderImagePath contains[cd] "TimeMachine"' --info給出以下日誌：
MacBook-Air-2:~ xxx$ log stream --style syslog --predicate 'senderImagePath contains[cd] "TimeMachine"' --info

奇怪的是：與日誌相反，74F8F302-361C-4490-9E35-1F2598F9D16E/A76BCEEB-A3BD-5D63-82F4-8AEBB2F5ACBA.sparsebundle實際上在我的共享中創建了一個名為的稀疏包。所以寫入權限絕對不是問題。

答案1
事實證明，我嘗試的配置不適用於 HFS+ 格式的磁碟機。使用 ext4 重新格式化磁碟機可以使錯誤消失，從而真正開始備份。
