yes.

No.

You need to use the "share" name as hash key. Since you're using XferMethod
tar, chances are your "share" is "/", so you'd have

  $Conf{BackupFilesExclude} = {
    '/' => [
      '/proc',
      '/sys',
      '/tmp'
    ],
    '/whatever/share/you/mean/by/backup' => [
      '/media'
    ]
  };

You *can* use '*' as hash key if you want the excludes to apply to every share
not explicitly given an exclude list, but it seems better practise (and less
error prone) to explicitly list excludes by share like you did.

Regards,
Holger
