My first words are "try to do your best RESISTANT". I think of course your database must be backup in some ways like RAID (Redundant Array of Independent Disks). But the difficult thing is that how can you restore your website. Is it all gone away or luckily you still have backup it too? The server can easy start again, but the website could be difficult to open again. In any case, I still look forward for your efforts of reopening the website and server.
