Yesterday Computer Song

Do you know the song "Yesterday"? Then sing along to this computer version. Yesterday, All those backups seemed a waste of pay. Now my database has gone away. Oh I believe in yesterday. 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.
