macos - fruit_pwrite_meta_netatalk：ad_pwrite 失败 - 通过 SMB 进行 Time Machine 备份

Question

我正在尝试将 SMB 用于 Time Machine 备份。我目前使用的是 macOS 10.15.5、Samba 4.11.6-Ubuntu 和 Ubuntu 20.04 LTS。

这是我的conf：

[timemachine]
   comment = Time Machine
   path = /mnt/HD/Backup/timemachine
   browseable = yes
   writeable = yes
   create mask = 0600
   directory mask = 0700
   spotlight = yes
   vfs objects = catia fruit streams_xattr
   fruit:aapl = yes
   fruit:time machine = yes
   fruit:time machine max size = 750G

我可以成功地将共享注册为时间机器磁盘，但是当它尝试备份时出现此错误：

[2020/07/17 05:53:28.442317,  0] ../../source3/modules/vfs_fruit.c:4637(fruit_pwrite_meta_netatalk)
  fruit_pwrite_meta_netatalk: ad_pwrite [071FEBFA-ACF7-5694-9FB6-A02D91AE7861.sparsebundle:AFP_AfpInfo] failed

如果我通过 Finder 挂载共享，我可以成功创建文件和文件夹。

你有什么线索吗？谢谢
