Re: [BackupPC-users] $Conf{BackupFilesExclude}?

This is due to the behavior of smbclient.  Here's an explanation
of how to make it work.

You sent me offlist your config file and XferLOG file.  Thanks.

The problem is that if you use wildcards (in particular "*") in
excludes, smbclient will only do the right thing if you use the
Windows-style directory separator '\' instead of '/'.

Therefore, instead of using something like this:

    $Conf{BackupFilesExclude} = {
      '*' => [
        '/Documents and Settings/*/Local Settings/Temporary Internet Files/',
        '/Documents and Settings/*/Local Settings/Temp/',
        '/Documents and Settings/*/NTUSER.DAT',
        '/Documents and Settings/*/ntuser.dat.LOG',
      ],
    };

you should use this:

    $Conf{BackupFilesExclude} = {
      '*' => [
        '\\Documents and Settings\\*\\Local Settings\\Temporary Internet Files',
        '\\Documents and Settings\\*\\Local Settings\\Temp',
        '\\Documents and Settings\\*\\NTUSER.DAT',
        '\\Documents and Settings\\*\\ntuser.dat.LOG',
      ],
    };

Also, you shouldn't include the trailing \ at the end of a
directory path.  You should either use:

    '\\FOO'

or

    '\\FOO\\*'

The first will exclude \FOO and all its contents.  The latter will
include the directory \FOO but similarly exclude its contents.

You can experiment with what works or doesn't work by manually
running smbclient, eg:

    setenv PASSWD XXXXXXX
    /usr/bin/smbclient \\\\HOST\\SHARE -I IPADDR -U USERNAME -E -N -d 1 \
            -c tarmode\ full -TcrX - \
            \\Documents\ and\ Settings\\\*\\Local\ Settings\\Temporary\ 
Internet\ Files \
            \\Documents\ and\ Settings\\\*\\Local\ Settings\\Temp \
            \\Documents\ and\ Settings\\\*\\NTUSER.DAT \
            \\Documents\ and\ Settings\\\*\\ntuser.dat.LOG \
        | tar tvf -

Note the additional escaping for the shell.  (Also, the -I IPADDR is
optional depending on your configuration.)
