Sing this to the tune of the Beatles' "Yesterday" : 

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 millstone 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. 
Oh, I believe in yesterday.
