I wanted to share a very recent experience I had that reinforced the importance of backing up your image files throughout a shoot.
I recently did a two day shoot in studio for a project. The shoot involved a 5 light setup, several different backdrops, and a large number of various props as well as 10 models. On both days we started shooting at 11 am and didn't wrap up until midnight - we had about a 1 hour break between models for makeup and set changes.
During the breaks I was very diligent about downloading my cards to my laptop, and then backing up the laptop files to a portable USB hard drive before I reformatted the card for the next shoot. At then end of the 2nd day of shooting, we packed up everything and, closed the studio and I bid adieu to the last model and my assistant.
I came back to my office, opened my laptop, and began to keyword the photos before transferring them to my desktop for cataloging and processing. I noticed there was about 2200 photos from the two days of shooting. Just as I started to work on the images, my laptop began acting erratically, so I rebooted it to start afresh, but then laptop refused to start up, couldn't be restored, and the software diagnostic CD stated the hard-drive could not be restored. Three days later, the laptop is still down and it looks like the hard-drive will need to be erased and the operating system software will need to be reinstalled.
Because I had all the files on an external hard-drive, though, I was able to connect that to my desk top computer, transfer and backup all the files, and begin to work on them with no time lost because of the laptop failure. This is the first time this has happened to me, but I'm sure glad I had a good backup work-flow in place and I thought I'd share my experience here as a cautionary tale.
