As you most likely have noticed a few topics and posts have been lost because of DB corruption.
The info below is quoted form the Technical Bazaar:
So from a cursory inspection, something went
wrong with the DB. The post data seems to be present, but some of the
other tables are apparently corrupted. It might be possible to save a
bunch of data if you put enough work into it, but my recommendation
would be to just restore from last night's backup, to get the site up
again as quickly as possible with some data loss. The backup is dated
2:25 AM server time, which I assume is before the DB got messed up.
