Suddenly,
 There's not half the files there used to be,
 And there's a milestone hanging over me
 The system crashed so suddenly.

 I pushed something wrong
 What it was I could not say.
 Now all my data's gone
 and I long for yesterday-ay-ay-ay.

 Yesterday,
 The need for back-ups seemed so far away.
 I knew my data was all here to stay,
 Now I believe in yesterday.
