I'm using a docker image of BackupPC 4.4 which has smbclient 4.14. My
backups have been SMB failing on a Win 10 client and I'm trying to
figure out why.
My command line is:
/usr/bin/smbclient \\\\MACHINE\\Documents -U USER%PASSWORD -E -d 5 -c
tarmode\ full\ nosystem\ nohidden -mSMB2 -TcX - '*My*'
The result I get is:
tar:716 do_list fail NT_STATUS_ACCESS_DENIED
tar:633 tar_process done, err = 1
In the increased debugging log, I see:
tar:923 +++ \Fax\Inbox
tar:976 get_file skip dir \Fax\Inbox
NT_STATUS_ACCESS_DENIED listing \My Music\*
NT_STATUS_ACCESS_DENIED listing \My Pictures\*
NT_STATUS_ACCESS_DENIED listing \My Videos\*
dos_clean_name [\OneNote Notebooks\.]
unix_clean_name [\OneNote Notebooks\.]
When I list the share, I can see those directories are hidden and are
likely legacy junctions:
My Music DHSrn 0 Sun Mar 21 07:05:29
2021
My Pictures DHSrn 0 Sun Mar 21 07:05:29
2021
My Videos DHSrn 0 Sun Mar 21 07:05:29

As you can see in my command line, I've attached to disable system and
hidden files and even excluded anything with My in it. None of this
seems to work.
I'm not a developer but have been around code for a while so I tried to
look at the smbclient source code. I can see here in clitar.c [1] line
716 the error. This comes from the do_list() function which passes the
get_file_callback function. In that function I see that it should be
attempting to exclude system and hidden files but my guess is the
listing is the problem before it even calls in the callback in client.c
[2].
Is there something else I can do to exclude these files?

I'm not quite sure what you're trying to do ... if I'm reading this
right, you're trying to exclude a junction point called "My Music" (for
example). It's neither a system nor a hidden file, so that won't
exclude it.
Normally, you'd just add such junction points to
$Conf{BackupFilesExclude}. You might want to list what you've tried
here, the traditional path to exclude is '\\Users*Documents\\\\My
Music', and so on.
