If the database tables are destroyed then nothing can be recuperated from there. Your best hope is that your host has a recent backup.

my question is can I make my site or phpbb have its own database for copy or dump for make it save on me hard drive.
As I mentioned before, you can probably make backups through your host control panel. And phpBB has it's own ACP section which allows you to make backups and download them. The thing is that backups aren't made automatically. Someone, usually the site administrator, has to initiate that.

I don't understand what you are trying to say. perhaps you mean "before" your site is reinstalled?
Never rely on your host to take care of your site.
Always make your own backups (at regular intervals) adn keep a working copy of your site on PC (using personal server software).
What you need to do now is to ask your host to put back the latest backup of your site (and perhaps ask them if they have taken measures to block future hacking attempts).
