Yes, I back things up. Regularly. However, on this particular occasion, I was mid work on thousands of images when, by some moronic motion, I threw away the entire photographic folder that I had worked all summer on. Added new categories, sorted and sorted... arranged, and started to upload the work here. Made it to "Ornamental" folder (alphabetical folder sorting.. so yeah, on the O section) and that when I threw the folder away. Not only did I throw it away, but I emptied the recycle bin without a thought. As a matter of fact, I didn't notice I did this for 2 days. I was about to proceed to upload that O category, when I realized I couldn't find it, nor any of the other categories.
I tried to reclaim the thrown out folder with various programs, but that didn't work either. It was too late, the info was already being written over.
Now, as I said, I have back up... but It's all the work before I worked so hard on it. Basic loss of 3 months of work. I was submitting here daily until then.. and I'm just now working up to getting back at it. Sigh...
But, i've come to realize that no matter the format, film, slide, digital, print.. anything can happen to rob you of your work. Easy come... easy go... I try to be Zen about it.
