我真的同意这个。我的目标是前面带有可选标签的快照以及未标记的快照在 Windows 中显示为以前的副本，例如文件名，例如：

/mnt/pool1/.snapshots/Backup/GMT-2023.07.16-12.53.26
/mnt/pool1/.snapshots/Backup/Sometagname_GMT-2023.07.16-12.53.26
/mnt/pool1/.snapshots/Backup/anothertagname23_GMT-2023.07.16-12.53.26

如果我按如下方式设置 smb.conf，Windows 将按预期看到未标记的卷影副本。

shadow:snapdir = /mnt/pool1/.snapshots/Backup
shadow:basedir = /mnt/pool1/Backup  
shadow:sort = desc
shadow:format = GMT-%Y.%m.%d-%H.%M.%S
shadow:localtime = yes

我已经尝试了我能想象到的正则表达式和设置的每种组合，但我找不到达到此目的的shadow:snapprefix和shadow:delimiter的值。例如，以下是我尝试过的一些组合：

shadow:format = %Y.%m.%d-%H.%M.%S
shadow:localtime = yes
shadow:snapprefix = ^[A-Za-z0-9]\{0,\}\(_\)\{0,1\}\(GM\)\{1\}
shadow:delimiter = T-
shadow:format = %Y.%m.%d-%H.%M.%S

shadow:format = GMT-%Y.%m.%d-%H.%M.%S
shadow:localtime = yes
shadow:snapprefix = ^[A-Za-z0-9]*\(_\)?
shadow:delimiter = GMT-
shadow:format = GMT-%Y.%m.%d-%H.%M.%S

任何帮助将非常感激，因为我已经花了几个小时来研究组合和在线搜索！

我正在使用 Samba 设置 Ubuntu 服务器。文件系统是 BTRFS，我似乎无法让 Windows 从快照中查看以前的版本。

我的 smb.conf 有这个共享：

[Backup]
    path = /mnt/pool1/backup
    comment = Share for backups
    writeable = yes
    delete readonly = yes
    browseable = yes

    vfs object = recycle shadow_copy2

    recycle:repository = /mnt/pool1/backup/.recycle/%U
    recycle:touch = Yes
    recycle:keeptree = Yes
    recycle:versions = Yes
    recycle:noversions = *.tmp,*.temp,*.o,*.obj,*.TMP,*.TEMP
    recycle:exclude = *.tmp,*.temp,*.o,*.obj,*.TMP,*.TEMP
    recycle:excludedir = /.recycle,/tmp,/temp,/TMP,/TEMP

    shadow:snapdir = /mnt/pool1/snapshots/backup
    shadow:basedir = /mnt/pool1/backup
    shadow:sort = desc
    shadow:format = GMT-%Y.%m.%d-%H.%M.%S

目录结构如下：BTRFS卷挂载在/mnt/pool1，共享和快照目录位于该级别：

ll /mnt/pool1
total 20
drwxr-xr-x 1 root root    98 Jul 14 09:14 ./
drwxr-xr-x 4 root root  4096 Jul 14 09:13 ../
drwxrwxr-x 1 root users   74 Jul 14 11:28 backup/
drwxrwxr-x 1 root users    0 Jul 13 16:50 docker/
drwxrwxr-x 1 root users    0 Jul 13 16:49 homes/
drwxrwxr-x 1 root users    0 Jul 13 16:51 install/
drwxrwxr-x 1 root users    0 Jul 13 16:51 media/
drwxrwxr-x 1 root users   80 Jul 13 16:58 snapshots/
drwxrwxr-x 1 root users    0 Jul 13 16:51 timemachine/

ll /mnt/pool1/snapshots
total 16
drwxrwxr-x 1 root users  80 Jul 13 16:58 ./
drwxr-xr-x 1 root root   98 Jul 14 09:14 ../
drwxrwxr-x 1 root users 184 Jul 14 11:55 backup/
drwxrwxr-x 1 root users   0 Jul 13 16:58 docker/
drwxrwxr-x 1 root users   0 Jul 13 16:58 homes/
drwxrwxr-x 1 root users   0 Jul 13 16:58 install/
drwxrwxr-x 1 root users   0 Jul 13 16:58 media/
drwxrwxr-x 1 root users   0 Jul 13 16:58 timemachine/

使用的结构是快照目录每个共享都有一个子目录。您可以在我已有的快照上看到文件名：

tree -a
.
├── backup
│   ├── .recycle
│   │   └── ubuntu
│   │       └── File from windows - Copy.txt
│   ├── File from windows.txt
│   └── test.txt
├── docker
├── homes
├── install
├── media
├── snapshots
│   ├── backup
│   │   ├── GMT-2023.07.14-09.19.31
│   │   │   └── test.txt
│   │   ├── GMT-2023.07.14-09.30.57
│   │   │   └── test.txt
│   │   ├── GMT-2023.07.14-09.57.41
│   │   │   └── test.txt
│   │   └── GMT-2023.07.14-10.48.31
│   │       └── test.txt
│   ├── docker
│   ├── homes
│   ├── install
│   ├── media
│   └── timemachine
└── timemachine

我在日志中找不到任何内容可以帮助调查此问题，并且似乎没有任何方法可以从服务器端诊断问题所在。谁能建议这里可能出了什么问题或者我如何获得更多诊断信息？非常感谢，亚瑟
