if you're using rsync(d), then, yes, what you enter as $Conf{RsyncShareName}
is the (list of) share name(s). You need to use *either* these *exact* values
as keys in BackupFilesExclude or the literal value * for "all shares for which
there is no matching key". For example,

(i.e. $Conf {RsyncShareName} = [ '/home', '/var' ]), then the following
(alternative) examples would give you meaningful excludes:

# 1.) exclude /home/cache, no excludes under /var
$Conf {BackupFilesExclude} = {
        '/home' => [ '/cache' ],
};

# 2.) exclude /home/cache and /var/cache
$Conf {BackupFilesExclude} = {
        '*' => [ '/cache' ],
};

# 3.) exclude /home/foo and /var/cache (note how the * entry matches /var
#     because there is no explicit entry for /var, and how it doesn't match
#     /home because there is an explicit entry)
$Conf {BackupFilesExclude} = {
        '/home' => [ '/foo' ],
        '*' => [ '/cache' ],
};

# 4.) exclude /home/cache and /var/cache (note how the /home/ entry doesn't
#     match /home because it is not literally identical, even though file
#     system semantics would suggest otherwise)
$Conf {BackupFilesExclude} = {
        '/home/' => [ '/foo' ],
        '*' => [ '/cache' ],
};

Since you *appear* to have $Conf{RsyncShareName} = '/home', it would be

$Conf {BackupFilesExclude} = {
        '/home' => [
                '/theplans/log',
                '/run/positions/trace',
                '/hun/res/received'
        ]
};

presuming you also want to exclude the directories. If you want to get them
and only exclude the contents of the directories, add the '/*' as you did
above.

Excludes and includes are always specific to the XferMethod used. For more
details on what you can do with rsync(d), see the rsync man page. For tar and
smb, the syntax may differ, though in the simple case (only fixed paths, no
wildcards) it should work much the same (though smb always seems to cause
confusion with the path separators).

Hope that helps.

Holger
