I save everything on my hard drive and then to an additional portable hard drive once a week.
Another thing that I do that you might want to try is I opened up a G Mail account (Google) that you get a unbelievable amount of space on.
Everytime I email a
inspection report, I'll also BCC a copy to my G mail account. That way if I'm out and need to access my reports I can go easily to that account and resend something or make a change if need be. I also put each inspection report along with the pictures in a zip folder with the buyers name, the address so it can be easily found and put in the email to myself. I'm using their space at Google for a back-up you might say.
Its free, take advantage of it.
