Again and again I am convinced of the correctness of Murphy's Law.
I never had problems with my camera, but I used it to make a simple pics of my city, cat etc. Most of them aren't interesting even for me, so I simply delete it.
Week ago I tried to make a couple of fetish pic for completing the requests. I prepared the scene, lighting etc, and... and I see that my camera's battery is low, and I can't find the charger. It always laid on my desk (for three years), and now... after two days of search I can't find it

My bondage collection is damaged. And what pictures are damaged the most? The most valuable, of course: my first renders, not the usual paysites bondage crap.
And my DAZ studio content is damaged too. I can't find again some of the very valuable props and textures. So if you're working with DAZ/Poser/Carrara... simply DO BACKUPS of the valuble props source.
