YESTERDAY - by bill gates

Yesterday, All those backups seemed a waste of pay.
Now my database has gone away.
Oh I believe in yesterday.
Suddenly, Theres not half the files there used to be,
And theres a milestone hanging over me
The system crashed so suddenly.
I pushed something wrong
What it was I could not say.
Now all my datas 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,
I believe in yesterday.
