Is this database MyISAM or Innodb? With MyISAM you just need to copy
the directory and change its name (of course), with Innodb, you can
use mysqldump, and then redirect the resulting file into your server.
Of course, you should ALWAYS copy your data dir, and have some kind of
backup for emergency purposes. There's also a tool (can't remember its
name) for innodb hotcopy... You can search for it.
