[Comm] Bacula и regex | wild в наборе файлов

Доброго времени суток.

Пробую при помощи Bacula 3.0.3 забрать бекапы репозиториев (они сделаны 
отдельным скриптом). Все файлы имеют вид SVN*gz.
Не получается скопировать только их - жадная Бакула копирует всё в 
целевой папке. Создаётся впечатление, что RegEx и Wild не работают на 
включение файлов в бекап.

Попытка 1:

# This is the backup of the SVN
FileSet {
   Name = "SVNDump"
   Include {
     Options {
         signature = MD5
         RegEx = "^/tmp/SVN.*gz$"
         }
     File = "/tmp"
    }
}

Проверяю:

estimate job=BackupSVN listing client=storeFd001

...

drwxrwxrwt 7 root root 240 2010-01-18 15:32:13 /tmp

2000 OK estimate files=15 bytes=33,633

Хм.... если добавить exclude = yes , регулярное выражение начинает работать:

Привожу отрывок из документации:
Now, lets assume you only want to backup .Z and .gz files and nothing 
else. This is a bit trickier because Bacula by default will select 
everything to backup, so we must exclude everything but .Z and .gz 
files. If we take the first example above and make the obvious 
modifications to it, we might come up with a FileSet that looks like this:

FileSet {
   Name = "Full Set"
   Include {                    !!!!!!!!!!!!
      Options {                    This
         wildfile = "*.Z"          example
         wildfile = "*.gz"         doesn't
                                   work
      }                          !!!!!!!!!!!!
      File = /myfile
   }
}

The *.Z and *.gz files will indeed be backed up, but all other files 
that are not matched by the Options directives will automatically be 
backed up too (i.e. that is the default rule).

To accomplish what we want, we must explicitly exclude all other files. 
We do this with the following:
FileSet {
   Name = "Full Set"
   Include {
      Options {
         wildfile = "*.Z"
         wildfile = "*.gz"
      }
      Options {
         Exclude = yes
         RegexFile = ".*"
      }
      File = /myfile
   }
}
The "trick" here was to add a RegexFile expression that matches all 
files. It does not match directory names, so all directories in /myfile 
will be backed up (the directory entry) and any *.Z and *.gz files 
contained in them. If you know that certain directories do not contain 
any *.Z or *.gz files and you do not want the directory entries backed 
up, you will need to explicitly exclude those directories. Backing up a 
directory entries is not very expensive.

Огромное спасибо! Заработало:

FileSet {
   Name = "SVNDump"
   Include {
     Options {
         signature = MD5
         Wildfile = "/tmp/SVN*gz"
         }
     Options {
         Exclude = yes
         RegexFile = ".*"
         RegexDir = ".*"
     }

     File = "/tmp"
    }
}

Стыд и позор моей невнимательности =\
