Keeping backup copies of your work

A recent HDR image.

At present I've been doing a lot of HDR (Hyper Dynamic Range) photography documenting some of the abandoned places around the Piedmont, Virginia area.

It go me to thinking that when you have multiple copies of an image you need to keep a good backup as you work.

Most of my HDR work involves combining three images and then three or four edited Tiff files before I make the final prints. What this means is that I will have somewhere around 12 different images before I arrive at the final print. If I ever want to restart the process I need to keep everything!!

What this means is it's important to backup at least once or twice a week in order not to get into a jam.
