A few years ago:

In the process of transferring MySQL data to a new disk, I accidentally rm'ed the actual MySQL directory, instead of the symlink that I had previously set up for it.

My guts felt like dropping through to the floor.

In a panic, I asked my colleague: "What did those databases contain?"

C: "Raw data of load tests that were made last week."

Me: "Oh.. does that mean that they aren't needed anymore?"

C: "They already got the results, but might need to refer to the raw data later... why?"

Me: "Uh, I accidentally deleted all the MySQL files... I'm in Big Trouble, aren't I?"

C: "Hmm... with any luck, they might forget that the data even exists. I got your back on this one, just in case."

Luck was indeed on my side, as nobody ever asked about the data again.
