Yesterday, I managed to delete the primary database that we use at work.  I won’t go in to how this happened, other than to say: Fuck you MySQL Workbench.  I was trying to get a map of the table relations within the database.  Needless to say, it didn’t work.  After the immediate pants-wiping, I restored the database from the backup. But the backup was from the previous morning, as the current backup hadn’t finished.  Unfortunately, I couldn’t find the files from the mornings backup.

In short, losing data sucks.  How often do database “pros” backup their data?

This code is MySQL specific, but should be applicable anywhere, really.
