Yesterday: A DBA's backup song
(To be sung to the tune of 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 deadline
hanging over me
The system crashed so suddenly.
I pushed something wrong
What it was I could not say
Now my data's gone
and I long for yesterday-ay-ay-ay.
Yesterday,
The need for back-ups seemed so far away.
Thought all my data was here to stay,
Now I believe in yesterday.
Sorry, couldn't resist.
Seriously. Get a good beginners book about Linux adminstration and try to be more paranoid when it comes to important data.
