How much backup is too much backup? As a person who spends most of her waking hours searching for lost items, I believe in backup. I wish regular life had a search engine. Last year I bought a 2 tetrabyte external hard drive. (Mathematically speaking, I think that means a gazillion-willion bytes, more that a mortal could possibly use.) I admit I was smug about my backup. To free up space on my hard drive (I have an extraordinary number of images stored), I would just transfer files to the external hard drive and put the originals in the trash.
It will come as no surprise to anyone but myself that my external hard drive died. The tech said, 'well you have backup for it, right?'
'Back up for my backup? How could I, every damn portal on the computer is filled, where would I plug in another back up?'
'No,' he replied, 'backed up on your computer.' This rapidly devolved into a bad "who's on first?" routine.
It has not been a good day.
