Well you know people here will say they don't use the ubb backup because their board is very large and it takes to long, Backup crashes because file is to large(Bla,bla,bla)
But I think for people new at least it would be a useful tool until they get their feet wet.
It could be just a simple stand alone script using the config.inc.php file. Which has everything needed.
And by the way the backup does not save that file either just the tables.
