Topic: DB Backup Idea
Well i just came up with thise idea,
So basicly every hour your sites DB is backed up and a file is deleted from 48 hours ago (or whatever time you set) if your site is hacked, you can open the backups and see them in your site (you can navagate through hours using a button on top of the header).
Also if you want to add something to the DB you would have to enter a password in the admin block and add the file into the DB within 1 minute of each other.
Although PunBB is already extremly secure this would make it almost hack safe.
