After validating a new link I tried building pages. I got an error message about the device being full. The db was wiped clean, the back up was wiped clean. The backup of the entire site the server makes is empty. I had no copy of the db at home. I lost it all. Even the counter file was zeroed. Catagories remained.

I'm pretty sure this was a case of really bad timing and a server problem, not a Links problem. I will always keep a backup copy of links off the server from now on.
