Thanks to Leisl Ashbaugh at OSU CCME for sharing this:

Do you know the song "Yesterday"? Then sing along to this computer version.

If you don't know it see the youtube video below.

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.
