Everything gets erased. What do you do?

Hypothetical situation here. All of your Achievements, Game memories, Online ranks/unlocks and Profiles get mysteriously erased and no one can do anything to fix it. What do you do? Do you go back and get everything back, start over and redo everything that has been undone or do you give up and find a new hobby?

if you were connected to Live, you wont lose your achievements, they have everyone's profiles backed up on probably 3 or 4 server banks. game saves, thats your job to hold on to.

Most achievements I have are from games I don't even own, so I wouldn't bother playing them over again. I really don't even actively go after achievements anyway. Unless they actually sound like an enjoyable challenge, I just let the achievements unlock passively.

I wouldnt play the games i already played over again just for some achievements.I play to actually just play the game.The acheivements just make things interesting for me,thats why i like to do them.

Id be pretty pissed for some games i am half way through and not have all the achievements yet.I maybe would do some of those over again.

I lost some of my achievements because of some problem with either getting a new Xbox or Xbox Live, I can't remember, but I just knuckled down and tried to retrieve them.
