Luckily I did back up in July so I at least have my photograhs from Japan. My first reaction was one of relief that I had at saved those irreplaceable photos.
Then I remembered that my back-up was done in July of 2002, so I don't have any of the photographs of the cats (except for those I have on my webpage so that they could be linked in livejournal).
I also lost several personal journal entries, conversations, passwords, tax documents, and personal sentimental things that I really should have backed-up since July.
I'm going to go vacuum something.
